Effect of dicyandiamide on nitrogen transformation of ammonium bicarbonate in soil

Abstract

Abstract: Incubation studies on the effect of dicyandiamide (DCD) on NH₄⁺-N dynamics of ammonium bicarbonate (AB) in soil show that whether mechanical mixed with AB or being a component of slow releasing AB,DCDinhibits the nitrification of NH₄⁺-N and decreased the ammonium volatilization, which made soil preserve more NH₄⁺-N in a longer period and buffered the intensity of soil acidification or alkalization after ABapplication.Adding DCDcould increase the utility efficiency of AB,and decrease its nitrogen losses.
