COMPLEX FERTILIZER AND METHOD FOR ITS PREPARING Russian patent published in 2005 - IPC

FIELD: agriculture.

SUBSTANCE: the present innovation deals with cultivating agricultural varieties both in irrigated and nonirrigated farming as complex fertilizer. The latter includes dried manure, mineral fertilizers and microelements. Manure is represented as an oil cake of processing products of common and Ural's licorice rhizomes and roots for extracts and products of 2-4-yr-long decomposition of pig manure 15-20 weight%, 3-4-yr-long decomposition of poultry dung 15-20 weight% and cattle litter of organic origin of 2-yr-long decomposition 50-55 weight%. As micro-fertilizers one should apply the brine of natural mineral - bischofite of sulfate type of the following formula MgCl₂ 6·H₂0 of 1.20-1.35 t/cu. m - the rest. Method for preparing the complex fertilizer includes manure processing and introduction of mineral fertilizers and microelements. Products of decomposition of 2-4-yr-long period of pig and cattle manure and poultry dung should be reduced and separated into fraction of 2-5 mm to be supplemented with licorice root oil cake and mixed. Then it is necessary to add bischofite brine due to finely divided spraying the drops onto components in manure fractions. Then the mixture obtained should be dried up to 16-22% moisture content. Application of the present innovation enables to increase crop yield in agricultural varieties and keep soil fertility.

EFFECT: higher efficiency of application.
