Atrazine leaching from biochar-amended soils.
The herbicide atrazine is used extensively throughout the United States, and is a widespread groundwater and surface water contaminant. Biochar has been shown to strongly sorb organic compounds and could be used to reduce atrazine leaching. We used lab and field experiments to determine biochar impacts on atrazine leaching under increasingly heterogeneous soil conditions. Application of pine ch...
متن کاملSorption, degradation and leaching of pesticides in soils amended with organic matter: A review
The use of pesticides in modern agriculture is unavoidable because they are required to control weeds. Pesticides are poisonous; hence, they are dangerous if misused. Understanding the fate of pesticides will be useful to use them safely. Therefore, contaminations of water and soil resources could be avoided. The fates of pesticides in soils are influenced by their sorption, decomposition and m...
متن کاملSorption of Atrazine by Biochar Prepared from Manioc Wastes in Tropical Soils
On the basis of OCED Guideline 106, batch sorption studies were employed to reveal sorption of atrazine by amending biochar in tropical soils, namely, laterite, paddy soil and dry red soil. Biochar,a micro-porosity and great surface product, was generated by pyrolysis of manioc wastes at 750°C(BC750) and modified substances(MC750) were produced by loading Fe. The mechanism of sorption was exami...
متن کاملPhosphorus Sorption by Gravels in Lateritic Soils
t The effect of sesquioxidic i i ic gravels (>2 mm size fraction) on phosphorus sorption by two gravelly lateritic soils was investigated by phosphorus sorption experiments, X-ray diffraction, ti , autoradiography and electron microscopy. In one soil the abundance and size of gravels l decreased downslope. As the gravel content of both soils increased (13-61%), ), the proportion of large (>8 mm...
متن کاملPhosphorus Dynamics in Broiler Litter-Amended Soils
Because land application of broiler litter is commonly made in the spring before cropping season and in the fall, it is essential to understand how environmental variations, such as temperature, affect the phosphorus (P) dynamics. A laboratory incubation study was conducted at Waste Management and Forage Research Unit, USDAARS with the objective of determining the effects of temperature and soi...
