title: Biochar alters hydraulic conductivity and inhibits nutrient leaching in two agricultural soils

description: Biochar is purported to provide agricultural benefits when added to the soil, through changes in soil water hydraulic conductivity (Ksat), and increased nutrient retention through chemical or physical means. Despite increased interest and investigation, there remains uncertainty regarding the ability of biochar to deliver these agronomic benefits due to differences in biochar feedstock, production method, production temperature and soil texture. In this project, a suite of experiments was carried out using biochars of diverse feedstocks and production temperatures, in order to determine the biochar parameters which may optimize agricultural benefits. Sorption experiments were performed with seven distinct biochars to determine sorption efficiencies for ammonium and nitrate. Only one biochar effectively retained nitrate, while all biochars bound ammonium. The three biochars with the highest binding capacities (produced from almond shell at 500 and 800 °C (AS500 and AS800) and softwood at 500 °C (SW500)) were chosen for column experiments. Biochars were amended to a sandy loam and a silt loam at 0 and 2% (w/w) and saturated hydraulic conductivity (Ksat) was measured. Biochars reduced Ksat in both soils by 64-80%, with the exception of AS800, which increased Ksat by 98% in the silt loam. Breakthrough curves for nitrate and ammonium, as well as leachate nutrient concentration, were also measured in the sandy loam columns. All biochars significantly decreased the quantity of ammonium in the leachate, by 22 to 78%, and slowed its movement through the soil profile. Ammonium retention was linked to high cation exchange capacity and a high oxygen to carbon ratio, indicating that the primary control of ammonium retention in biochar-amended soils is the chemical affinity between biochar surfaces and ammonium. Biochars had little to no effect on the timing of nitrate release, and only SW500 decreased total quantity, by 27 to 36%. The ability of biochar to retain nitrate may be linked to high surface area, suggesting a physical entrapment rather than a chemical binding. Together, this work sheds new light on the combined chemical and physical means by which biochar may alter soils to impact nutrient leaching and hydraulic conductivity for agricultural production.

title: Electron Backscatter Diffraction maps for quartz, plagioclase, and K-feldspar from migmatitic aluminous schists located in the Wet Mountains, central Colorado

description: Former melt films preserved along subgrain and grain boundaries were investigated using a combined Electron Backscatter Diffraction (EBSD) and Energy Dispersive Spectroscopy (EDS) approach in migmatitic aluminous schists from the Wet Mountains of central Colorado. We determined the quartz grains that host the former melt was deformed but the former melt films themselves are undeformed, indicating quartz deformation precedes melting. Here, we include EBSD data for quartz, plagioclase, and K-feldspar (.ctf files) to show that the former melt (feldspar) is undeformed.

title: Production time series of H2, CO2, CH4 and C2H4 production after comminution of Subglacial Lake Whillans sediments and solute composition of water.

description: Four depths within a sediment core collected in Subglacial Whillans were used to investigate the potential contributions from crushing to the gas and nutrient pool in subglacial environments. These depths were used to produce three samples: SLW Top (0-4 cm), SLW Mid (an amalgamation of 14- 16 and 28-30 cm depths) and SLW Bot (36-38 cm). Sediment samples were dried and disaggregated/crushed under low energy (LE), and then further crushed anoxically using a ball mill for 30 mins at 500 rpm (HE). Headspace gases were analysed immediately after high energy crushing. Subsamples of HE and LE crushed sediments were analysed to determine surface Si radicals produced and H2O2 produced after two minutes reacting with anoxic H2O2. Approximately 3g of HE and LE sediments were transferred to serum bottles, where they were incubated with 4ml of anoxic water. A dry control of HE sediment was kept for SLW Mid. Headspace gases were analysed before the addition of water and then again after 2 mins of reaction, with further headspace gas analysis taken after 1, 2, 5, 21 and 41 days. At the end of the incubation period, the slurry was filtered and analysed for concentrations of Na+, Mg2+, K+, Ca2+, F-, CH3COO-, Cl-, Br-, NO3-, SO42-, NH4+, NO2-, dissolved Si, PO43-, Fe2+ and total Fe.

title: Multi-year dust monitoring in eastern Patagonia

description: Total mass collected during multiple years at an average interval of 16-26 days in a BSNE and a CP collector in dust monitoring sites in Bahía Blanca (38.733ºS, 62.166ºW), Trelew (43.220ºS, 65.278ºW) and San Julián (49.300ºS, 67.772ºW). Bulk grain size distributions for selected samples were also measured for these sites and for a fourth site in Río Grande (53.786ºS, 67.751ºW). The purpose of these measurements was to obtain horizontal and vertical surface (i.e., 5 meters above ground level) dust mass fluxes close to dust-emitting surfaces in eastern Patagonia, as well as grain size distributions of dust.

title: XANES, XRD and Raman-spectroscopy data on Mn-rich phases on Lunéville château sandstones (patinas and bulks)

description: Lunéville château, in eastern France, presents Mn-rich dark patinas that developed either under natural conditions (rain and time) or after an accidental fire and exposure to significant volumes of water as part of attempts to extinguish the fire. The presented dataset characterizes both types of patinas in an effort to determine their formation mechanisms and Mn sources. In both cases, Mn required for patina formation likely derives from the reductive dissolution of Mn-rich minerals present in pristine sandstones, as suggested by the contrasting mineralogy and chemistry of Mn-rich phases present in the bulk and in the patina of a given building block. This dataset presents micro-XANES, micro-XRD and micro-Raman-spectroscopy data measured on Lunéville patinas but also on the Mn-rich areas in the sandstones bulks. The micro-XANES and micro-XRD experiments were conducted at the synchrotron SOLEIL facility, in LUCIA and DiffAbs beamlines, respectively.

title: Correlation of Bentonites from the Cretaceous Western Interior Seaway (KWIS)

description: Bentonites are layers of clay mienrals which are used as datums for startigraphic analysis. However,the extensiveness of bentonites over a study region makes it difficult to visually correlate them across space, especially when the lithology of the rock above and below the bentonite lays changes or the bentonites are not visible in certain areas. Here we attempt to geochmically correlate bentonites using Energy-Dispersive X-Ray Fluorescence (ED-XRF) to determine whether bentonites in the Cretaceous Western Inerior Seaway (KWIS) carry a unique elemental signature which can be used to correlate bentoniets from different geologic formation (Gallup Sandstone, Ferron Notom Delta, and Juana Lopez Member of the Cralisle Formation).

title: Jemez River Basin Soil Solution Chemistry 2019 (New Mexico, USA)

description: Soil solution samples in the Jemez River Basin field sites of the Catalina-Jemez Critical Zone Observatory (CZO) are collected with the following two types of soil solution samplers: i) Prenart Super Quartz suction cups (www.prenart.dk). Prenart suction cups are optimized for all chemistry analyses and were installed without addition of Si-slurry to allow for artifact-free Si analyses. Applied suction for each Prenart is ~ 60 kPa. ii) Custom made, fiberglass wick-based passive capillary wick samplers (PCaps, Perdrial et al. 2012). PCaps are optimized for water flux determination and sampling for organic carbon, most (non-carbonate) anions and trace metals. PCap samples should however not be used for major cations (Na, Mg, Si, K, Ca) and dissolved inorganic carbon because of artifacts from the fiberglass materials (see Perdrial et al (2014) for a complete list). Passive (continuous) suction, based on the length of the hanging water column, is ~3 kPa. Soil solution samplers were installed in each of six pedons in the Mixed Conifer Zero Order Basin (MC-ZOB) and the fire impacted site (2011 Burned ZOB) at 3 (PCaps) and 4 (Prenarts) depths, respectively. Pedon locations were selected to capture differences in catchment aspect (MC-ZOB SE facing: Pit 3 and 4, NW facing: Pit 1 and 6), landscape position (MC-ZOB: hollow Pit 2 and 5, planar Pit 1 and 6, divergent Pit 3, convergent Pit 4), elevation and burn severity (co-varying in 2011 Burned ZOB: low Pit 1 and 2, mid Pit 3, high Pit 4 to 6). Three new pedons were instrumented in the Unburned Mixed Conifer Site located in the San Antonio Mountain close to the Sulfur Spring in Fall 2015. These pedons are positioned 20 m from the flux tower US-Vcs. All samplers are collocated with Decagon soil moisture and temperature probes. MC-ZOB was subject to a high intensity wildfire (Thompson Ridge fire) in June 2013 and was then renamed to 2013 Burned ZOB.
