FIELD: agriculture.
SUBSTANCE: method to produce organo-mineral fertiliser includes composting of nesting manure of cattle, cattle humus, internal farm wastes, phosphogypsum and straw. The specified components are laid in layers onto a compacted clay site with deepened bottom at the following ratio of components (wt %): nesting manure of cattle - 65-75, cattle humus - 3-7, internal farm wastes - 2-5, phosphogypsum - 15-25, straw - balance. Monthly for 3.5-4 months before maturing, mixing is carried out with periodical moistening in dry period.
EFFECT: method makes it possible to produce organo-mineral fertiliser with preservation of organic substances and nitrogen in it, which has positive effect at soil and productivity of crops.
