FIELD: agriculture, in particular, cultivation of farm crops in irrigated and non-irrigated agriculture with the use of complex fertilizer. ^ SUBSTANCE: complex fertilizer contains dried manure, mineral fertilizers and microelements. Manure is formed as oil cake of reprocessed products of root and rootstock of licorice and Urals licorice and products of two-four year decomposition of pig dung 15-20 wt%, bird dung of three-four year decomposition 15-20 wt%, and organic litter of cattle of two-year decomposition 50-55 wt%. Brine of natural sulfate-type bischofite of MgCl2.6.H2O formulation having density of 1.20-1.35 t/m3 the balance is used as microelement. Method involves reprocessing manure and introducing mineral fertilizers and microelements; grinding decomposition products of two-four year decomposition time, such as pig, cattle and bird dung and separating into 2-5 mm size fractions; adding licorice root oil cake and mixing; introducing bischofite brine by fine dispersion of droplets into components in manure fractions; drying mixture to moisture content of 16-22%. ^ EFFECT: increased crop yield and provision for keeping of soil fertility. ^ 3 cl, 12 tbl |
