Effects of Different Nitrogenous Fertilizers and Dicyandiamide on Soil Ph and Bioavailability of Arsenic in Soil from South China

摘要

Shaking,incubation and kinetic laboratory experiments in this paper were conducted to determine effects of nitrogenous fertilizers and DCD on soil pH and bioavailability of arsenic in soil from south China.Three forms of N fertilizer (CO(NH2)2,(NH4)2SO4 and NH4HCO3) and Dicyandiamide (DCD)-C2H4N4 for nitrification inhibitor were studied in experiments.
