The effects of two plant species—soybean (Glycine max), and sunflower (Helianthus annuus) on nutrient availability in two soils (an organically farmed soil, OF, and a native grassland soil, GS, both Alfisols)—were measured with anion exchange membranes (Plant Root Simulator, PRS probes) in a greenhouse study. Vegetation (especially sunflower) in the OF soil caused significant reductions in soil...

ABSTRACT-Application of models for simulation of solute and pollutants transport in soil can reduce time and costs for remediation process. HYDRUS-1D model was developed to simulate the one–dimensional flow of soil water, heat, solute and viruses in variably saturated–unsaturated porous media. The objective of this investigation is to determine the solute transport parameters in disturbed soil ...

Soil compaction may affect N mineralization and the subsequent fate of N in agroecosystems. Laboratory incubation and field experiments were conducted to determine the effects of surface soil compaction on soil N mineralization in a claypan soil amended with poultry litter (i.e., Turkey excrement mixed with pine shavings as bedding). In a laboratory study, soil from the surface horizon of a Mex...

Plankton is an important food item of fishes and indicator for the productivity of a water body. The present study was conducted to evaluate the effects of bottom soil textural conditions on abundance of plankton in aquaculture pond. The experiment was carried out using three treatments, i.e., ponds bottom with sandy loam (T1), with loam (T2) and with clay loam (T3). The ranges of water quality...

much has been learned in recent years about the factors affecting reflection of sunlight by soils, the influence Knowledge of how surface roughness influences the reflectance of of w on albedo of rough soil surfaces is still poorly sunlight from cultivated soils is useful in various applications, such as estimating albedo values used as inputs to soil temperature models understood (Cresswell et...

Solanum nigrum cultivated on different soil texture types, sandy clay loam, silty clay loam, clay loam, loam, and control soils, were evaluated for proximate compositions, antinutrients, vitamins, and mineral composition with plant age using standard analytical methods. Accumulation of trace elements using translocation factor was studied to determine their toxic levels in plant tissues. Data w...

rainfall erosion processes a long with the rainfall characteristics can be affected by soil properties. the study was conducted to investigate the susceptibility of the aggregates in different soil textures to the rainfall erosion processes. the experiment was done on thirty soil samples recognized in four soil textures with different replications as the completely randomized design. ninety box...

[1] The evaluation of the relationship between satellitederived vegetation indices (normalized difference vegetation index and normalized difference water index) and soil moisture improves our understanding of how these indices respond to soil moisture fluctuations. Soil moisture deficits are ultimately tied to drought stress on plants. The diverse terrain and climate of Oklahoma, the extensive...

BACKGROUND The tidal flat is one of the important components of coastal wetland systems in the Yellow River Delta (YRD). It can stabilize shorelines and protect coastal biodiversity. The erosion risk in tidal flats in coastal wetlands was seldom been studied. Characterizing changes of soil particle size distribution (PSD) is an important way to quantity soil erosion in tidal flats. METHOD/PRI...
