METHOD FOR COMPLEX AMELIORATION OF SOLONETZ SOIL UNDER IRRIGATION CONDITIONS Russian patent published in 2008 - IPC A01B79/02 

FIELD: agriculture, may be used in soil science and plant growing during amelioration of black soil and light-chestnut soil.

SUBSTANCE: method involves providing soil agro-ameliorative investigation of plot; sowing winter farm crops, preferably wheat; harvesting grain simultaneously with straw grinding procedure and spreading ground straw over field; applying liquid manure and ameliorant such as ammoniated phosphogypsum in the form of semi-hydrate; embedding straw, liquid manure and ameliorant into soil surface layer by disking process using heavy disk-type tools, with amount of ground straw making at least 5-6 t/hectare, liquid manure - 40 t/hectare, and phorphogypsum - 6 t/hectare; plowing to 28-30 cm depth; sowing and cultivating phyto-ameliorant such as Sudan grass; providing ameliorant application to solonetz spots of black soil and to light-chestnut soil by continuous application process; repeating amelioration practices in five years on the basis of the same pattern.

EFFECT: increased efficiency of agricultural land and reduced costs of amelioration procedures.
