IMPACTOS AMBIENTAIS DA FERTILIZAÇÃO ORGÂNICA EM SISTEMAS AGROPECUÁRIOS NA REGIÃO SUL-BRASILEIRA

摘要: The application of organic fertilizers allows greater concentration P in the nutrient topsoil, however, this shift to deeper layers occurs slowly, especially on clay soil with higher binding sites. fertilizer liquid form when injected into grooves and applied bands reduce emission NH 3 -N, but raise rate denitrification, as well largest increase localized accumulation N-NO - before be absorbed by plants. straw hinders tillage fertilizer-soil contact access microorganisms for subsequent immobilization that may favor volatilization losses lower utilization Increasing doses promotes microbial activity, which is often measured CO 2 emissions, highest release soon after application.
