STUDY OF SOME PROPERTIES OF ORGANOMINERAL FERTILIZERSIN THE DEPENDENCE ON THE CONTENT IN THEIR COMPOSITIONOF THE ACTIVATED PEAT

The solution of the ecological and economic problems of agricultural productionis possible due to the use OMF, which manifest the biological activity and decreaseunproductive expenditures of fertilizers, their entering into the ground water. This isreached because organic matter of fertilizers is represented by lowland type native peatwith the inclusion chemically activated peat (hydrolyzate of peat), which is solid waste inproduction of growth stimulators by peroxide-ammonium hydrolysis method. Properties ofnitric-potassic organomineral fertilizers (OMF) and their organic content, depending onactivated peat content, and also the form of the utilized nitrogenous fertilizers, were investigatedin present study. The subject in our study was lowland type peat of «Dark» layer inTomsk region (65% humidity) and hydrolyzate of peat (solid residue from the production ofthe plant growth stimulators). Investigation of agrochemical properties of fertilizers, allowto assume the possibility of fertilizers production with the required ratio of moving elementsof nourishment (N: K). After evaluation of moving elements of nourishment, it was shownthat the dose of activated peat 10-15% in the composition of fertilizers has a maximum effecton their chemical and agrochemical properties, ensuring them effectiveness of action.Thus, usage of peat hydrolyzate in organomineral fertilizers ensure controlled mineralnourishment into the soil, increasing their economic effectiveness and ecological safety.
