FIELD: agriculture. SUBSTANCE: method involves agrochemical analysis; determining readjustment coefficients and calculating fertilizer doses, with soil agrochemical factors, farm crop agrotechnical factors and biological features being taken into consideration. When rice is cultivated, fertilizer doses are calculated with regard to additional effect of precursor in crop rotation as well as with regard to norms of carrying out of mineral feed elements, which depend upon yield level. EFFECT: reduced consumption of mineral fertilizers and provision for producing designed yield. 3 tbl, 1 ex
