Sorption and fractionation of dissolved organic matter and associated phosphorus in agricultural soil.
Mobility of dissolved organic matter (DOM) strongly affects the export of nitrogen (N) and phosphorus (P) from soils to surface waters. To study the sorption and mobility of dissolved organic C and P (DOC, DOP) in soil, the pH-dependent sorption of DOM to samples from Ap, EB, and Bt horizons from a Danish agricultural Humic Hapludult was investigated and a kinetic model applicable in field-scal...
متن کاملTopography Mediates the Influence of Cover Crops on Soil Nitrate Levels in Row Crop Agricultural Systems.
Supplying adequate amounts of soil N for plant growth during the growing season and across large agricultural fields is a challenge for conservational agricultural systems with cover crops. Knowledge about cover crop effects on N comes mostly from small, flat research plots and performance of cover crops across topographically diverse agricultural land is poorly understood. Our objective was to...
متن کاملInfluence of biochar amendments on the sorption-desorption of aminocyclopyrachlor, bentazone and pyraclostrobin pesticides to an agricultural soil.
The many advantageous properties of biochar have led to the recent interest in the use of this carbonaceous material as a soil amendment. However, there are limited studies dealing with the effect of biochar on the behavior of pesticides applied to crops. The objective of this work was to determine the effect of various biochars on the sorption-desorption of the herbicides aminocyclopyrachlor (...
متن کاملImpact of Agricultural Practices on Soil Nitrate Accumulation in the Jordan Valley: The Urgent Need for Soil Nitrogen Management Planning
The effect of agricultural practices on nitrate accumulation in soils of different farmland systems in the Jordan Valley (JV) is not yet documented. This study aims at quantifying nitrate concentrations in top-soil and investigating its spatial distribution in the JV in order to help developing a nitrogen management plan for the JV. Results showed that nitrate concentrations range from 88.2 to ...
متن کاملSorption of aged dicamba residues in soil.
The effect of aging (residence time in soil) on dicamba (3,6-dichloro-2-methoxybenzoic acid) and a major metabolite, 3,6-dichlorosalicylic acid (3,6-DCSA) sorption was determined in an unamended and a carbon-amended sandy loam and in a silt loam soil. During the incubation, sequential solvent extraction with 0.01 M calcium chloride solution and aqueous acetonitrile + hydrochloric acid was used ...
