摘要：
FIELD: agriculture.SUBSTANCE: invention relates to agriculture. Method comprises analysis of soil productivity taking into account abiotic factors by sampling soil for analysis, determining content of agrochemical indicators, determining factors of agroclimatic resource of the given territory, affecting crop capacity: photosynthetic active radiation (PAR), moisture supply, bio-hydrothermal potential (BHP), bioclimatic potential (BCP), determination of crop capacity of the selected crop depending on external and soil medium by formula:where: C - crop by the sum of ith factors； n is number of factors taken during crop calculation； i - factor influencing crop yield and yield increment - humus, phosphorus, potassium, acidity, microelements - indicators from agrochemical analysis of soil； Ci1 - crop ensured by i-factor soil fertility indicators； Ci2 - crop increment provided with additional i-factor； ai is the soil acidity effect correction factor, plotting the nomograph in form of a graph, selection for a specific crop according to a nomogram of a predicted crop index, placing a ruler on the nomogram and determining a required dose of fertilizer, wherein the fertilizer dose for the crop is set taking into account the provision of nutrients to the soil, calculating the yield gain of 1 t/ha of the crop, the main soil nutrient indices being humus, phosphorus and potassium.EFFECT: method ensures increase of soil fertility under forecast crop yield.1 cl, 9 dwg, 1 tbl, 1 exИзобретение относится к области сельского хозяйства. Способ включает анализ продуктивности почвы с учетом абиотических факторов путем отбора почвы для анализа, определения содержания агрохимических показателей, определение факторов агроклиматического ресурса данной территории, влияющих на урожайность культуры: фотосинтетической активной радиации (ФАР), влагообеспеченности, биогидротермического потенциала (БГТП), биоклиматического потенциала (БКП), определение урожайности выбранной сельскохозяйственной культ
