摘要: Increased consciousness about agricultural sustainability and health risks associated with agrochemicals has lead organic farming to be a globally emerging alternative farm practice. We report the effect of atmospheric deposition on soil quality heavy metal contamination produce under an system using wheat corn as test crops. Data obtained in open field (OFO) were compared plastic-covered glass-house-grown (OFG). The results showed that depositions Cd, Cu, Ni, Pb, Zn increased time. Soil porosity, water holding capacity, microbial biomass carbon (Cmic), substrate-induced respiration (SIR), alkaline phosphatase, FDAase activity decreased, whereas bulk density contents over time plots receiving deposition. Concentrations metals grains OFO crops exceeded safe limits Indian standards three sixfold higher than those recorded OFG plots. These re...
