FIELD: agriculture.
SUBSTANCE: inventions relate to the agriculture. Fertilizers mixture contains A. calcined-ammonium saltpeter based mineral fertilizer, which, in addition to the ammonium nitrate and calcium carbonate and/or magnesium carbonate and, if necessary, water, may contain up to 15 wt% of additional components, on the basis of calcined-ammonium saltpeter based mineral fertilizer without water, B. 100–10,000 pts.wt./mil. of 2-(N-3,4-dimethylpyrazole)succinic acid, on the basis of component A without water. Method of the fertilizers mixture production. Method of used in the agriculture or horticulture soil fertilization, wherein the fertilizers mixture is applied to the soil. Method of the of 2-(N-3,4-dimethylpyrazole)succinic acid production. 2-(N-3,4-dimethylpyrazole)succinic acid aqueous solution with greater than 7 pH value.
EFFECT: invention allows to produce the KAS-fertilizers mixture which, during storage and application, results in the nitrification inhibitor low loss, produce the effective nitrification inhibitor for KAS, which has low volatility during storage and use in the soil, as well as the KAS-fertilizers appropriate mixtures.
