Report from Lawrence Berkeley National Laboratory on the mechanisms of Actagro product - Proximus (AWD2725)
Abstract
Under a collaborative research and development (CRADA) agreement, LBNL scientists investigated the effect of the semi-humic substance, Proximus, on nitrogen dynamics in two contrasting soils. We specifically tested four hypotheses that Proximus (1) binds ammonium and reduces nitrification; (2) does not bind ammonium but chemically inhibits nitrification; (3) stimulates microbial immobilization of N in biomass; (4) stimulates denitrification. We performed two primary experiments, one in the laboratory using a pure culture of a nitrifying bacterium, and one in a greenhouse setting testing the fate of nitrogen and response of microbial communities in soils with and without Proximus.
