description: We present solution of self-consistent equations for the N3LO nuclear energy density functional. We derive general expressions for the mean fields expressed as differential operators depending on densities and for the densities expressed in terms of derivatives of wave functions. These expressions are then specified to the case of spherical symmetry. We also present the computer program HOSPHE (v1.00), which solves the self-consistent equations by using the expansion of single-particle wave functions on the spherical harmonic oscillator basis.

title: Anti-Semitic Folklore Motif Index
Creators: name: Bell, Sita
Publisher: name: Utah State University
Year: 2009

description: Anti-Semitism, or Jew hatred, much of which is expressed and communicated through folklore, has a long history and continues unabated today. Incendiary opinions, deadly misconceptions, and insidious accusations have plagued Jews throughout history. Anti-Semitic expressions and incidents are scattered throughout countless texts, but no single comprehensive reference work that compiles all forms of anti-Semitic folklore motifs exists. This thesis attempts to fill that gap by supplying an index of anti-Semitic motifs. To establish a baseline of already catalogued anti-Semitic motifs, all six volumes of Stith Thompson's Motif-Index of Folklore-Literature: A Classification of Narrative Elements in Folktales, Ballads, Myths, Fables, Mediaeval Romances, Exempla, Fabliaux, Jest-Books and Local Legends were scanned and any relevant motifs listed were archived in a card index. Approximately 250 more previously unidentified motifs were documented from historical materials, published books and articles, artifacts, and personal communications. All motifs used in this study were developed from English sources, or from English speakers borrowing from other languages and cultures. The procedure to categorize the folklore motifs is based on a numbering system developed by folklorist Stith Thompson in 1955. Using Thompson's classifications of motifs as a base, the approximately 250 newly identified anti-Semitic folklore motifs I discovered have been integrated with Thompson motifs. Anti-Semitic materials covered begin with the Middle Ages and continue to the present day. Although not comprehensive, this motif index incorporates examples of anti-Semitic folklore from all genres, making motifs and examples easily accessible for anyone who wishes to analyze historical and current anti-Semitism. Indexing anti-Semitic folklore in a single reference work based on a universal folklore indexing system creates a body of information to be used as a resource tool for education and research of anti-Semitism. Furthermore, the index can easily be expanded as more material comes to light.

description: Bi2Se3 is one of a handful of known topological insulators. Here we show that copper intercalation in the van der Waals gaps between the Bi2Se3 layers, yielding an electron concentration of ~ 2 x 10^20cm-3, results in superconductivity at 3.8 K in CuxBi2Se3 for x between 0.12 and 0.15. This demonstrates that Cooper pairing is possible in Bi2Se3 at accessible temperatures, with implications for study of the physics of topological insulators and potential devices.

title: Carbohydrate Derivatives in Antibiotics Research
Creators: name: Liang, Yi
Publisher: name: Utah State University
Year: 2009

description: In this study, we investigated the potential applications of carbohydrates in the development of new antibiotics. To tackle the problem of multidrug-resistant variants of M. tuberculosis (MDR-TB), we investigated the biosynthesis pathways of trehalose, which has contributed to significant drug resistance. Some new methods were developed for the synthesis of potential inhibitors (6-azido-trehalose and 6,6'-diazido-trehalose) that have been designed to imitate the intermediate molecule (trehalose 6-phosphate, TPP) of OtsA-OtsB pathway. At the same time, some new antibacterial agents based on trehalose have been synthesized. Members of the 1,2,3-triazole family have shown interesting biological properties. Steroid derivatives have been developed in antibiotics area. Therefore click reaction was utilized to build a 1,2,3-triazole ring and combine cholesterol with different carbohydrate moieties. A series of new compounds has been synthesized and their bioactivities have been tested.

Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: We present theoretical results on the deterministic and stochastic motion of a dumbbell carried by a uniform flow through a three-dimensional spatially periodic potential. Depending on parameters like the flow velocity, there are two different kinds of movement: transport along a potential valley and stair-like motion oblique to the potential trenches. The crossover between these two regimes, as well as the deflection angle, depends on the size of the dumbbell. Moreover, thermal fluctuations cause a resonance-like variation in the deflection angle as a function of the dumbbell extension.

Nucleation of cracks in a brittle sheet

description: We use molecular dynamics to study the nucleation of cracks in a two dimensional material without pre-existing cracks. We study models with zero and non-zero shear modulus. In both situations the time required for crack formation obeys an Arrhenius law, from which the energy barrier and pre-factor are extracted for different system sizes. For large systems, the characteristic time of rupture is found to decrease with system size, in agreement with classical Weibull theory. In the case of zero shear modulus, the energy opposing rupture is identified with the breakage of a single atomic layer. In the case of non-zero shear modulus, thermally activated fracture can only be studied within a reasonable time at very high strains. In this case the energy barrier involves the stretching of bonds within several layers, accounting for a much higher barrier compared to the zero shear modulus case. This barrier is understood within adiabatic simulations.
title: A Qualitative Exploration of the School Experiences of Middle-School Students in the Era of No Child Left Behind
Creators: name: Hamilton, Charles H
Publisher: name: Utah State University
Year: 2009

description: Since the inception of the most recent iteration of the Elementary and Secondary Education Act of 1965, No Child Left Behind (NCLB) has drawn widespread study and discussion. The majority of the research concerning NCLB has reported the perspective of teachers and administrative staff in public schools. The purpose of this research study was to add to the literature the voices of students. Participants in this qualitative research study were six students at Galaxy Junior High. These six students were interviewed multiple times. Based on a qualitative data analysis of their interview transcripts, and follow-up communications, four main categories of student experiences emerged: motivation in school, teaching methods, learning strategies, and connecting school and life. Participants discussed what motivates them in school, including intrinsic as well as extrinsic motivators; the method in which teachers teach; how they learn in school through the use of both bookwork and homework; and how school is the gateway to their future.
PEDOT:PSS microwave structures : fabrication, electromagnetic properties and applications
Creators: name: Dordanihaghighi, Marzieh
Publisher: name: University of British Columbia
Year: 2025

description: Electronic waste has become an environmental concern with the advent of the Internet of Things (IoT) and the new generation of wireless technologies due to the substantial increase in the manufacturing of metal based electronic components. The trend towards smaller and more powerful devices requires materials that offer both high performance and environmental sustainability, highlighting Intrinsically Conductive Polymers (ICPs) as key candidates for future technological advancements. Among different ICPs, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) stands out as a candidate due to its unique physical and electrical properties. Despite the progress made in PEDOT:PSS microwave structures, the detailed microwave behavior of this material and its interaction with electromagnetic waves have remained unexplored. This thesis delves into the electromagnetic properties of PEDOT:PSS-based structures within the microwave regime, investigating factors that influence their microwave responses, and evaluating their performances in different applications. This research is structured into two primary streams: wired and wireless microwave structures. In the first stream, the study examines the electromagnetic properties of PEDOT:PSS microstrip lines with variable thicknesses from 2 μm to 16 μm, and PEDOT:PSS patch resonators doped with various concentrations of dimethyl sulfoxide (DMSO) from 0 wt.% to 8 wt.%. The experimental setup involves measuring the microwave response of these structures across different frequency bands and validating the results with simulations in various software. The findings reveal that the thickness of the PEDOT:PSS layer significantly impacts the propagation efficiency of microwave signals, and the dopant concentration influences the material’s sensitivity to relative humidity changes. In the second stream, the study investigates the absorbing capabilities of multilayer PEDOT:PSS thin films and explores the use of PEDOT:PSS patterned surfaces for sensing applications. The research demonstrates that multilayer structures with varying distances from the electromagnetic source and different layer arrangements exhibit distinct reflection responses. Additionally, the PEDOT:PSS patch resonator array shows promising results as a microwave-absorbing surface and a sensitive element for humidity detection. The split ring resonator composed of DMSO-doped PEDOT:PSS and silver nanowires effectively distinguishes between different standard liquids based on their complex permittivity and can be implemented as a flexible structure for a wide range of non-intrusive sensing applications. This comprehensive study advances the understanding of PEDOT:PSS’s behavior in the microwave regime and underscores its suitability and tunability for various microwave applications.

description: We present results on a free-space atom interferometer operating on the first order magnetically insensitive |F=1,mF=0> -> |F=2,mF=0> transition of Bose-condensed 87Rb atoms. A pulsed atom laser is output-coupled from a Bose-Einstein condensate and propagates through a sequence of two internal state beam splitters, realized via coherent Raman transitions between the two interfering states. We observe Ramsey fringes with a visibility close to 100% and determine the current and the potentially achievable interferometric phase sensitivity. This system is well suited to testing recent proposals for generating and detecting squeezed atomic states.

Comparison theorems for the Dirac equation with spin-symmetric and pseudo-spin-symmetric interactions

description: A single Dirac particle is bound in d dimensions by vector V(r) and scalar S(r) central potentials. The spin-symmetric S=V and pseudo-spin-symmetric S = - V cases are studied and it is shown that if two such potentials are ordered V^{(1)} \le V^{(2)}, then corresponding discrete eigenvalues are all similarly ordered E_{κν}^{(1)} \le E_{κν}^{(2)}. This comparison theorem allows us to use envelope theory to generate spectral approximations with the aid of known exact solutions, such as those for Coulombic, harmonic-oscillator, and Kratzer potentials. The example of the log potential V(r) = v\ln(r) is presented. Since $V(r)$ is a convex transformation of the soluble Coulomb potential, this leads to a compact analytical formula for lower-bounds to the discrete spectrum. The resulting ground-state lower-bound curve E_{L}(v) is compared with an accurate graph found by direct numerical integration.

description: Poly[tris(dimethylformamide)(μ3-2,4,6-triiodol-1,3,5-benzene tricarboxylic acid)-praseodymium (III)] {Pr(TIBTC)(DMF)3}n (1) (H3TIBTC = 2,4,6-triiodo-1,3,5-benzene tricarboxylic acid) was synthesized by the reaction of Pr(NO3)3·6H2O and H3TIBTC at 85°C in a pyrex vial. 1 was characterized by elemental analysis, IR, UV–vis, TGA, PXRD, and atomic force microscopy analytical means. Each of the central Pr ions and the three carboxyl groups from the same ligand constitute a SBU, which is then joined by a carboxyl group to form a building block. In order to further explore the functional properties of 1, we used this compound for adsorption experiments. It is found that 1 can effectively adsorb anionic dyes in aqueous solutions.

Creators: name: Drakos, Nicole
Publisher: name: Zenodo
Year: 2021
Subjects: Challenges for theory, modeling, and synthetic observations

description: Ultra-deep surveys, such as the Hubble Ultra Deep Field (HUDF) and the Hubble Frontier Fields (HFF), have probed the faint end of galaxy luminosity functions (LFs) out to redshift ~ 10, and helped us understand the evolution of galaxies and their role in reionization. Limitations to these previous surveys include their small fields of view that were insufficient to probe the environment and clustering of galaxies and their small samples of galaxies at the high-redshift faint-end of the LF. In contrast, the upcoming Roman Space Telescope (RST) will image a much larger field of view than previous facilities, and can conduct ultra-deep surveys that cover areas more than ~100 times the size of the HUDF. To study the science return of RST ultra-deep fields, we have developed a mock catalog that includes galaxy positions, redshifts and SEDs. Mock catalogs are crucial to test processing and analysis tools, and to identify potential observational biases, and are therefore instrumental for planning extragalactic astrophysics investigations. In this presentation, we describe the construction of the RST Ultra Deep Field mock catalog and our plans to make the catalog public.
COSMOS2020 a stepping stone for the next generation of galaxy surveys
Creators: name: Weaver, John R.
Publisher: name: Zenodo

Subjects: Challenges for theory, modeling, and synthetic observations

description: COSMOS is one of the most valuable fields of observation for extragalactic science, due in part to continued investment in multi-chromatic observation. It is then no surprise that it has played a pivotal role in our understanding of galaxy evolution, especially at early times where sources are too faint to be studied en masse by comparably shallow, wide-field surveys. Now in the decade of groundbreaking optical-NIR facilities such as the Nancy Roman Space Telescope, alongside JWST, LSST, and Euclid, the stage is set to probe deeper into the Universe than ever before. COSMOS is the natural stepping stone in this progressively deeper investigation and has been selected as one of the primary calibration fields for forthcoming surveys. It is for these reasons why we must continue to innovate. We present COSMOS2020, the latest installment of catalogs to map COSMOS, now at unprecedented optical-NIR depths in excess of 28 mags over 2 deg2. A total of 37 bands of photometry are newly extracted for 1M sources using bleeding-edge profile-fitting photometry provided by The Tractor. We find intensely competitive measurements compared to an identical extraction with SExtractor, benchmarked by photometric redshift accuracy below 2% at i < 24. Incredibly, we show that The Tractor provides the incredibly robust high-redshift photometry with remarkably little photometric redshift bias, underscoring the transformative role of profile-fitting photometry in the next generation of galaxy surveys.
Modeling Nebular Emission in Cosmological Galaxy Formation Simulations

Subjects: Challenges for theory, modeling, and synthetic observations

description: Nebular line emission diagnostics have been instrumental in studying the galaxy properties over the years. As we move into the era of next generation telescopes giving us a wider access to the high redshift universe the applicability of these diagnostics are put into question. We are working on developing a self consistent model of nebular emission using state of the art cosmological hydrodynamic galaxy formation simulation (SIMBA) and photoionization code (CLOUDY). We have adopted a novel approach where we have developed the first-ever model for calculating the nebular emission line spectrum on a particle-by-particle basis for cosmological galaxy formation simulations which is a significant step forward from more commonly-used lookup-table methods. We have already developed a basic framework and shown in a pilot study that it can reproduce the observed SDSS-DR8 BPT curve. In this talk, I will be going over the modeling details and results from the pilot study as well as some preliminary diagnostic calibration for high redshift galaxies.

description: The spectral emission of neutrinos from a plasma in nuclear statistical equilibrium (NSE) is investigated. Particular attention is paid to the possible emission of high energy (>10 MeV) neutrinos or antineutrinos. A newly developed numerical approach for describing the abundances of nuclei in NSE is presented. Neutrino emission spectra, resulting from general Fuller, Fowler, Newman (FFN) conditions, are analyzed. Regions of T-rho-Ye space favoring detectability are selected. The importance of critical Y_e values with zero net rate of neutronization (Ye dot) is discussed. Results are provided for the processing of matter under conditions typical for thermonuclear and core-collapse supernovae, pre-supernova stars, and neutron star mergers.

title: Hydraulics of IDEal Drip Irrigation Systems
Creators: name: Thompson, Evan J
Publisher: name: Utah State University
Year: 2009

description: The hydraulics of IDEal drip irrigation system components were analyzed under controlled laboratory conditions and the results can be applied to the design of IDEal systems. The hydraulic loss coefficient for the lateral-submain connector valves was determined based on laboratory measurements. It was found that the hydraulic loss due to friction in the lay-flat laterals can be accurately estimated with standard friction loss equations using a smaller effective diameter based on the wall thickness and inlet pressure head. The equivalent length barb loss, expressed as an equivalent length of lateral, was calculated for button emitters, as well as for micro-tubes inserted to lengths of 5 and 10 cm. It was concluded that the barb loss is essentially constant over the micro-tube insertion range of 5-10 cm. The head-discharge relationship and coefficient of manufacturer's variation of pre-punched lateral holes (without emitters), button emitters, and micro-tubes were characterized. Finally, several IDEal drip irrigation systems in the Central Rift Valley of Ethiopia were evaluated in the field. Recommendations were given for future research and improvements in the manufacturing, installation, operation, and maintenance of IDEal drip irrigation equipment.

Studying Morphology & Quenching of Galaxies in the NGRST Era using Interpretable Convolutional Neural Networks
Creators: name: Ghosh, Aritra
Publisher: name: Zenodo
Year: 2021
Subjects: Challenges for theory, modeling, and synthetic observations

description: The traditional methods of obtaining morphological classifications of galaxies are not scalable to the large data volumes expected from future surveys like NGRST. To overcome this, we have developed a publicly available convolutional neural network (CNN) called Galaxy Morphology Network (GaMorNet) that classifies galaxies according to their bulge-to-total light ratio. GaMorNet does not need a large amount of real data for training and can be applied to datasets with a range of signal-to-noise ratios and spatial resolutions. We have used GaMorNet to study the quenching of star formation in ∼100,000 (z∼0) SDSS and ∼20,000 (z∼1) CANDELS galaxies using morphology-separated color-mass diagrams. We first trained GaMorNet on simulations of galaxies and then transfer-learned using ∼25% of each data set to achieve misclassification rates of ≲5%. Using the GaMorNet classifications, we find that bulge- and disk-dominated galaxies have distinct color-mass diagrams. For both datasets, disk-dominated galaxies peak in the blue cloud, across a broad range of masses, consistent with the slow exhaustion of star-forming gas. In contrast, bulge-dominated galaxies are mostly red, with much smaller numbers down toward the blue cloud, suggesting rapid quenching and fast evolution across the green valley. We have also used a combination of different CNN visualisation techniques to investigate GaMorNet’s decision-making process, making our results interpretable and robust.

description: The paper is devoted to the problem of classification of extremal positive maps acting between $B(K)$ and $B(H)$ where $K$ and $H$ are Hilbert spaces. It is shown that every positive map with the property that $\rank ϕ(P)\leq 1$ for any one-dimensional projection $P$ is a rank 1 preserver. It allows to characterize all decomposable extremal maps as those which satisfy the above condition. Further, we prove that every extremal positive map which is 2-positive turns out to automatically completely positive. Finally we get the same conclusion for such extremal positive maps that $\rank ϕ(P)\leq 1$ for some one-dimensional projection $P$ and satisfy the condition of local complete positivity. It allows us to give a negative answer for Robertson's problem in some special cases.

title: Nitrogen and Phosphorus Dynamics as Applied to Water Quality Under Management Intensive Grazing
Creators: name: Thacker, Vaughn J
Publisher: name: Utah State University
Year: 2009

description: Contamination of freshwater systems by nutrients has been studied extensively in the eastern U.S. Little research on the fate of nutrients in grazing conditions has been done in the western U.S. Western agriculture is often irrigated and research addressing the potential for leaching under these conditions is warranted. This study used Management Intensive Grazing (MIG) and eight grass-legume mixtures to evaluate the management and forage choice in relation to nitrogen and phosphorus leaching to ground water. Soil water samples were taken weekly through the growing season from 2001 through 2003. Water samples were analyzed for nitrate, ammonia, and phosphate. Soils were described and a textural discontinuity was discovered in two of the six soil profiles described. Data were analyzed by treatment, grass, legume, and soils by treatment. Three-year nitrate-N means were found to be in a range of 4.50 to 48.10 and 2.11 to 49.5 mg NO3 - -N L-1, at 60 cm and 90 cm, respectively. The amount of leaching depended on the grass-legume mixture as well as the soil characteristics. Significant differences were found between grasses (P=0.0001) with tall fescue leaching the least and orchardgrass leaching the most. Differences in leaching under legumes were also found to be significant (P=0.001), with white clover always leaching more than birdsfoot trefoil when significant differences were observed. Ammonia leaching was nonsignificant at a studywide analysis. Phosphorus treatment concentrations ranged from 0.025 to 0.41 mg PO4- -P L-1 and were significantly different (P=0.001). A comparison by grass type indicated that perennial ryegrass leached significantly higher concentrations of P (P=0.01) at 60 cm than the other grasses, but found no difference at 90 cm. No significant differences were found between legumes at either depth. Leaching of P was less affected by the soil textural discontinuity than nitrogen leaching. Soil differences affect leaching in varying degrees. Nitrate was affected most strongly by soil differences. These differences were more strongly evident at 60 cm than 90 cm. Soils affected phosphorus leaching differently than nitrate, and were more strongly affected at 90 cm than at 60 cm. Ammonia was not affected by soil characteristics.
title: Development of a Survey Measuring Visitor Satisfaction and Service Quality of Cultural and Natural Sites in Belize
Creators: name: Wiberg, Dustin S.
Publisher: name: Utah State University
Year: 2009

description: The literature suggests that a correlation exists between visitor satisfaction and a visitor's choice to re-experience a product. The higher one's satisfaction level, the more likely he/she is to experience the product again and/or provide positive word-of-mouth advertising to friends and family. The Tian-Cole and Crompton model was chosen because of its acknowledgment and explanation of the differences between Visitor Satisfaction (VS) and Service Quality (SQ) and how their relationship influences satisfaction and contributes to Future Destination Selection. In addition to identifying a theoretical framework that explains why visitors return, it was necessary to identify a survey methodology to be used in developing the Mountain Pine Ridge Forest Reserve (MPRFR) visitor satisfaction surveys. It was determined that a combination of the Relative Performance Assessment (RPA) and Customer Service Questionnaire (CSQ) was an appropriate survey framework for a visitor satisfaction survey. As a result of the research, two visitor satisfaction surveys were developed: Intercept Survey and Mail-back Survey. The Intercept Survey will be administered at a MPRFR site. It was designed to be concise and not take much of the visitor's time. This survey will be used to gather general information about visitor characteristics and level of satisfaction while at a site. The Mail-back Survey will be sent to the visitor after their trip so more time can be devoted to answering a more detailed visitor satisfaction survey. This survey asks visitors to indicate what site characteristics are important to them and then rate their satisfaction with each item. Instruments from the report entitled "A Front Country Visitor Study for Grand Staircase-Escalante National Monument" were used as an example of how to format a visitor satisfaction survey and how to use the collected data as a managerial tool. The two main objectives of this research were accomplished and have established a foundation upon which subsequent research efforts will begin. This work serves as a catalyst to improving Belizean site planning, design, and management by better understanding what site characteristics contribute to visitor satisfaction.

description: We report on 0.3-10 keV X-ray observations by the Chandra X-ray Observatory of the fields of 22 sources that were discovered as hard X-ray (20-100 keV) sources by the INTEGRAL satellite (IGR sources). The purpose of the Chandra observations is to localize the sources and to measure their soft X-ray spectra in order to determine the nature of the sources. We find very likely Chandra counterparts for 18 of the 22 sources. We discuss the implications for each source, considering previous results and new optical or IR identifications, and we identify or suggest identifications for the nature of 16 of the sources. Two of the sources, IGR J14003-6326 and IGR J17448-3232, are extended on arcminute scales. We identify the former as a pulsar wind nebula (PWN) with a surrounding supernova remnant (SNR) and the latter as a SNR. In the group of 242 IGR sources, there is only one other source that has previously been identified as a SNR. We confirm a previous identification of IGR J14331-6112 as an High-Mass X-ray Binary (HMXB), and we suggest that IGR J17404-3655, IGR J16287-5021, IGR J17354-3255, IGR J17507-2647, IGR J17586-2129, and IGR J13186-6257 are candidate HMXBs. Our results indicate or confirm that IGR J19267+1325, IGR J18173-2509, and IGR J18308-1232 are Cataclysmic Variables (CVs), and we suggest that IGR J15529-5029 may also be a CV. We confirm that IGR J14471-6414 is an Active Galactic Nucleus (AGN), and we also suggest that IGR J19443+2117 and IGR J18485-0047 may be AGN. Finally, we found Chandra counterparts for IGR J11098-6457 and IGR J18134-1636, but more information is required to determine the nature of these two sources.

description: A family of exact solutions is presented which represents a rigidly rotating cylinder of dust in a background with a negative cosmological constant. The interior of the infinite cylinder is described by the Godel solution. An exact solution for the exterior solution is found which depends both on the rotation of the interior and on its radius. For values of these parameters less than a certain limit, the exterior solution is shown to be locally isomorphic to the Linet-Tian solution. For values larger than another limit, it is shown that the exterior solution extends into a region which contains closed timelike curves. At large distances from the source, the space-time is shown to be asymptotic locally to anti-de Sitter space.

Effects of a low soil biochar application rate on nutrient dynamics in a coarse textured agricultural soil

description: Biochar is an agricultural soil amendment, used both as a carbon sequestration tool and to alter soil physical and chemical properties, and in turn, water and nutrient dynamics. Commonly, studied biochar application rates exceed 10 t/ha, a rate that represents both a large environmental draw and economic investment for farmers. The objective of this study was to evaluate the effects of a low, more realistic biochar application rate (3 t/ha) on leachate, soil, and crop nutrient dynamic in a coarse texture soil. To do so, field and greenhouse studies were conducted over two growing seasons each. In spring 2022 biochar was applied in its “pristine” state, and a “charged” state after being mixed with nutrient-rich slurry dairy manure. Spring wheat (Triticum aestivum L.) was grown at Totem Plant Science Field Station (Vancouver, BC) in both 2022 and 2023, with nutrient concentrations in soil and wheat, along with yield, measured after each season. In the first year, there was an increase in soil K with charged biochar and decreased yield with pristine biochar, relative to the control (no treatment application). By the second year, there were no differences in yields, and only an increase in total soil N was observed with charged biochar. The findings of the field study were complemented by the greenhouse study, in which spring wheat was grown in treatment-amended field soil in columns, and leachates were collected. Similar to the field study, the year one greenhouse study showed an increase in available soil K with both biochar treatments and lower yield with pristine biochar treatment. In the second year there was a temporary increase in leached K with charged biochar, while yield changes from year one did not persist to year two. Ultimately, charging biochar ameliorated the negative impact of pristine biochar on crop response in year one, although by year two, the impact of charging was less pronounced. These studies suggest that a more realistic application rate of 3 t/ha of biochar can significantly affect nutrient dynamics with the charging of biochar leading to predominantly positive outcomes.
