Research methods - were studied and compared different methods of activation of phosphorites - mechanical activation at disintegration of phosphorites, raw materials treatment in the alkaline and acid medium, thermal treatment. Physical and chemical methods of research with using of spectrophotometers, pH-metres, conductometer, atom-absorption spectrometry method were applied in the work. It was proved, that by the methods of acid, salt and thermal treatment of mineral raw materials of Ukraine under offered technological schemes was possible to receive mineral fertilizers. It is possible with application of PAA to receive fertilizers with the prolonged action and waterretaining effect at the working enter-prises, and also in farms of Ukraine. The offered technological schemes of fertilizers production have no analogues. The received trial parties of fertilizers have been used at field experiments carrying out on cultivation of grain and vegetable cultures. Productivity of grain crops was increased on 8 - 12 %, vegetables - on 10 - 30 % in comparison with usual fertilizers. Application sphere - agriculture and the working enterprises for produce of fertilizers.
