Predicting Iron Chlorosis of Lupin in Calcareous Spanish Soils from Iron Extracts
Authors: de Santiago Ana , Delgado Antonio
Published: September 2006

Iron deficiency chlorosis is a major nutritional problem affecting sensitive cultivated plants in calcareous soils. Our main objective was to study the suitability of various Fe extracts for predicting the incidence of Fe deficiency chlorosis in calcareous soils from southern Spain. Six single Fe extractions were used: unbuffered hydroxylamine (room temperature), DTPA (diethylenetriaminepentaacetic acid) at 2 and 17 h, “rapid” ammonium oxalate, ammonium oxalate, and pyrophosphate. The Fe forms that account for most of the Fe supplied to plants were studied by using a sequential Fe fractionation process involving four extractants: citrate–bicarbonate, citrate at pH 6, citrate–ascorbate (a mild reductant), and citrate–bicarbonate–dithionite (a strong reductant). Suitability of Fe extracts for predicting Fe chlorosis was checked by establishing correlations between the amount of Fe extracted from soil and the chlorophyll content in white lupin (Lupinus albus L.). The amounts of Fe extracted by hydroxylamine accounted for a minimal portion of Fe associated with oxides, thus indicating that this extractant is not efficient at reducing Fe oxides. Hydroxylamine Fe, however, accounted for 63 and 72% of the variance in chlorophyll meter readings at 2 and 3 wk of growth, respectively, in contrast to “rapid” oxalate (32 and 11%) and DTPA at 2 h (29 and 15%). At 3 wk of growth, the variance in meter readings explained by hydroxylamine Fe was much higher than that explained by the active CaCO3 equivalent (56%). This ability of hydroxylamine Fe to predict chlorophyll meter readings is due to the relationship of the Fe extract to poorly crystalline Fe fractions, which showed the strongest relationship with the active CaCO3 content (R2 = 0.84, P < 0.001).

Published: September 2006

The purpose of this 4‐yr study was to evaluate tall fescue (Festuca arundinacea L.) production and changes in soil P fractions resulting from alum‐treated poultry litter (ATPL) applications. Plots were established in the spring of 2000 at Orange, VA, on a Davidson loam (fine, kaolinitic, thermic Rhodic Kandiudult). Treatments included the application of ATPL, non‐treated poultry litter (NPL) and triple superphosphate (TSP) at rates based on current litter management strategies in Virginia. During the 4 yr of this study, applications of ATPL resulted in forage yield and P uptake similar to that found in treatments receiving NPL. Also, no significant differences in Mehlich‐1 extractable soil P between litter treatments were observed after 4 yr of application. A soil P fractionation procedure revealed significantly decreased H2O extractable inorganic P (Pi) concentrations in soils receiving N‐based rates of ATPL compared with equivalent applications of NPL. Conversely, the organic P (Po) fraction extracted with 0.1 M NaOH was significantly elevated in treatments that had received ATPL compared with those receiving NPL or TSP regardless of P application rate. The results indicate that applications of ATPL does not adversely affect P uptake by fescue or forage production. This study also shows that ATPL can have an impact on the forms of P found in soils following continued applications; however, these differences may not always be detected through routine soil analyses such as the Mehlich‐1 extraction.
Estimating Dissolved Phosphorus Concentrations in Runoff from Three Physiographic Regions of Virginia

Published: September 2006

The relationship between STP (soil test P) and DRP (dissolved reactive P) in runoff has been shown to vary with soil type due to differences in soil properties. The purpose of this study was to determine if soil tests could indirectly take into account differences in soil properties and thus provide one relationship with STP and runoff DRP among a variety of soil types. Nine different soil types were sampled from four different fields to provide a range in STP. Unamended soils were packed into runoff boxes for use in a rainfall simulation study. All soils were analyzed for P, Al, and Fe using various extractions, and correlated to runoff DRP concentrations from all soils when grouped based on soil type and physiographic region. Slopes and intercepts were unique to soil type for the STP vs. runoff DRP relationship among all soil P tests except for WSP (water‐soluble P) slopes, resulting in an overall universal slope of 0.0125 mg DRP L−1, which agrees with past studies. The y intercepts from the soil WSP vs. runoff DRP relationship were well related to soil clay content (negative relationship) in addition to the fact that Coastal Plain soils had a significantly greater y intercept than Piedmont and Ridge and Valley soils when grouped by physiographic region. This suggests that Coastal Plain soils possess a greater potential for releasing DRP into runoff compared with Ridge and Valley and Piedmont soil at equivalent WSP values. This study provides a means with which to estimate potential runoff DRP concentrations by use of soil WSP and clay content.
Refinement of the Differential Water Loss Method for Gypsum Determination in Soils
Authors: Artieda O. , Herrero J. , Drohan P. J.
Published: September 2006

Determining the gypsum content in soil is lengthy and cumbersome using methods based on SO4 determination. Moreover, as these methods do not strictly titrate gypsum, inaccuracies can be produced by the presence of sulfate minerals other than gypsum. The thermogravimetric properties of gypsum, however, allow determination of its content in a rapid and easy way sufficiently accurate for many pedologic purposes. Our objective was to expand the lower limit of gypsum detection to make the test useful for soil classification and management. We have refined the differential water loss method by estimating the gypsum percentage from the loss of water in the soil sample between 70 and 90°C. Our results, compared with gravimetric determinations of precipitated BaSO4, found coefficients of determination of 0.98 for gypsum contents ranging from 2 to 50%, and 0.99 for contents >50%. The method is valid for gypsum contents >2% and thus improves previous estimation procedures.
Estimating Saturated Hydraulic Conductivity In Spatially Variable Fields Using Neural Network Ensembles
Authors: Parasuraman Kamban , Elshorbagy Amin , Si Bing Cheng
Published: September 2006

Modeling contaminant and water flow through soil requires accurate estimates of soil hydraulic properties in field scale. Although artificial neural networks (ANNs) based pedotransfer functions (PTFs) have been successfully adopted in modeling soil hydraulic properties at larger scales (national, continental, and intercontinental), the utility of ANNs in modeling saturated hydraulic conductivity (Ks) at a smaller (field) scale has rarely been reported. Hence, the objectives of this study are (i) to investigate the applicability of neural networks in estimating Ks at field scales, (ii) to compare the performance of the field‐scale PTFs with the published neural networks program Rosetta, and (iii) to compare the performance of two different ensemble methods, namely Bagging and Boosting in estimating Ks Datasets from two distinct sites are considered in the study. The performances of the models were evaluated when only sand, silt, and clay content (SSC) were used as inputs, and when SSC and bulk density ρb (SSC+ ρb) were used as inputs. For both datasets, the field scale models performed better than Rosetta The comparison of field‐scale ANN models employing bagging and boosting algorithms indicates that the neural network model employing the boosting algorithm results in better generalization by reducing both the bias and variance of the neural network models.
Soil Hydraulic Conductivities and their Spatial and Temporal Variations in a Vertisol
Authors: Das Gupta Surajit , Mohanty Binayak P. , Köhne J. Maximilian
Published: September 2006

Knowledge of soil hydraulic parameters and their spatiotemporal variation is crucial for estimating the water and solute fluxes across the land–atmosphere boundary and within the vadose zone at different scales. The objective of this study was to determine soil hydraulic conductivities [saturated hydraulic conductivity, Ksat, and unsaturated hydraulic conductivity, K(Ψ)] and their spatial and temporal variations in a clay‐dominated biporous Vertisol near College Station, TX, using tension infiltrometers. The study was conducted within a 20‐ by 16‐m plot across several seasons during a 21‐mo period (May 2003–January 2005) to investigate the impact of varying disk sizes (measurement support) on K(Ψ), and the spatial and temporal variations of K(Ψ) under natural environmental conditions due to pore space evolution. Infiltration occurred in a bimodal fashion consisting of preferential flow (occurring at soil water pressure heads [Ψ] = −0.05 to 0 m) and matrix flow (at Ψ = −0.2 to −0.1 m). Biological and structural macropores present in the soil resulted in gravity‐dominated flow near saturation (Ψ = −0.05 to 0 m) for all experiments. The Student's t‐test of analysis of variance indicated that hydraulic conductivities were not affected by changes in the infiltration disk sizes. Although the K(Ψ) values at four different locations within the plot did not show significant spatial variability, they demonstrated strong temporal variation during the 21‐mo period based on the evolution of natural environmental conditions due to seasonal precipitation, root growth and decay, and structural pore space dynamics. Temporal trends of K(Ψ) indicated that hydraulic conductivities close to saturation were positively correlated with antecedent moisture conditions reflecting liquid cohesion, water films bridging across cracking peds, and the activation of flow in biological and structural macroporosity in the biporous soil system.
Co‐witness feedback in line‐ups
Authors: Skagerberg Elin M.
Published: September 2006

The aim of the current study was to establish whether feedback from a co‐witness concerning their choice of suspect could influence an individual witness' certainty and other testimony‐relevant judgements. Eighty‐two university students and members of the general public viewed a film of a staged mugging in pairs and then made an identification of who they thought was the suspect from a culprit‐absent line‐up (i.e. identification parade). The participants were then required to tell their partner whom they had identified and to fill out a questionnaire with testimony‐relevant questions (e.g. How good a view did you get of the person in the line‐up?). When the pairs of participants agreed on their choice of suspect, their scores on the testimony‐relevant questions tended to be higher than when the pairs did not agree. This shows that co‐witnesses can influence each others' memory reports when giving each other feedback after the identification process. The implications of these findings are discussed.

Effects of magnetic field on the antioxidant enzyme activities of suspension‐cultured tobacco cells
Authors: Sahebjamei Hassan , Abdolmaleki Parviz , Ghanati Faezeh
Published: September 2006

Effects of magnetic fields (MFs) on the activities of antioxidant enzymes of suspension‐cultured tobacco cells were investigated. Compared with the control cells, exposure of the cells to static MF with the magnitudes of 10 and 30 mT for 5 days, 5 h each day, increased the activity of superoxide dismutase (SOD). In contrast, the activity of the catalase (CAT) and ascorbate peroxidase (APX) was decreased by MF, compared with those of the control cells. Level of lipid peroxidation was also increased by MF. It suggests that MF could deteriorate antioxidant defense system of plant cells. Bioelectromagnetics. © 2006 Wiley‐Liss, Inc.
Survey of residential 50 Hz EMF exposure from transformer stations
Authors: Szabó Judit , Jánossy Gábor , Thuróczy György
Published: September 2006

In Hungary it is typical that 10/04 kV transformer stations are being installed in multistory residential and office buildings. Magnetic fields (MFs) up to several tens of µT have been measured in apartments close to transformers. The aim of the present study was to provide systematic assessment of MF exposure of residents living above transformer stations. Out of 41 addresses provided by the electricity supplier, current load of 21 transformers and MF in 21 apartments was measured. Spot MFs at 1 m height and time weighted average 24 h MF exposure at bed height was measured. All‐day personal MF exposure was measured at waist and HOME exposure was calculated. BED exposure was measured at bed height. Participants kept a time‐activity diary. The time‐weighted average 24 h MF exposure (3.03 µT) exceeded the usual residential exposure (<0.2 µT). The mean HOME and BED personal exposure above transformers was 0.825 and 1.033 µT, respectively. Our study provides exposure assessment of a cohort with a wider exposure range, compared to power‐line epidemiological studies. Bioelectromagnetics. © 2006 Wiley‐Liss, Inc.
The effect of induced biphasic pulsed currents on re‐epithelialization of a novel wound healing model
Authors: Bullock Anthony J. , Barker Anthony T. , Coulton Leslie , MacNeil Sheila
Published: September 2006

The coordinated migration of keratinocytes is crucial to cutaneous wound healing; failure of keratinocytes to migrate into a wound can lead to chronic non‐healing wounds. Keratinocyte migration can be influenced by applied electrical fields. Our aim was to investigate whether keratinocyte migration could be accelerated by applying an induced biphasic pulsed electrical field. We developed two in vitro biological systems models for this purpose: a keratinocyte colony‐forming model and a reconstituted skin wound healing model with biphasic pulsed currents. Our in vitro skin models were capable of generating trans‐epithelial potentials (TEP) similar to in vivo mammalian skin. Histological examination of the wound healing model also indicated that re‐epithelialization occurred in a similar manner to that seen in vivo, although no evidence of a reconstitution of a basement membrane was seen during the 14 days in vitro experimental period. We found that growth of keratinocyte colonies and keratinocyte migration in an in vitro wound bed were not significantly affected by induced short duration biphasic pulsed currents at a frequency of 0.5 Hz of 100 and 200 mV/mm.

Authors: Foliart Donna E. , Mezei Gabor , Iriye Richard , Silva J. Michael , Ebi Kristie L. , Kheifets Leeka , Link Michael P. , Kavet Rob , Pollock Brad H.
Published: September 2006

We examined the association between magnetic field (MF) exposure and the presence of prognostic risk factors among 482 children diagnosed with acute lymphoblastic leukemia (ALL) between 1996 and 2001. Personal 24‐h MF measurements were obtained for 412 children; 386 children were included in analyses. There were no trends seen between increasing exposure to MF and the presence of adverse clinical and tumor‐specific prognostic factors. Our results suggest that exposure to MF is not associated with the presence of unfavorable cytogenetic abnormalities in leukemic blast cells or with clinical factors at the time of diagnosis that predict poor survival.
