Abstract

The kinetics of changes in the mobile forms of phosphorus (Р2О5) of traditional and biomodified phosphorus fertilizers (BMРF) in the soil has been studied. It has been established that the kinetics of the transition of mobile forms of Р2О5 of phosphorus fertilizers into an indigestible form depends on the time of interaction of fertilizers with soil. Mobile forms Р2О5 of biomodified phosphorus fertilizers BMРF-Ammophos, BMРF-Suprephos NS, BMРF-PS-Agro remain in the soil for a significantly longer time compared to mobile forms Р2О5 of traditional phosphate fertilizers Ammophos, Suprefos NS, PS-Agro. It is shown that the highest level of mobile forms of Р2О5 fertilizers, one month after application, was found in the soils of biomodified fertilizers BMРF-Ammophos, BMРF-Suprephos NS and BMРF-PS-Agro (respectively 48-50 and 34 mg/kg of soil). While the content of mobile P2O5 in soils with traditional fertilizers on the 30th day, the measurement was only 24-25 mg/kg of soil.
