FIELD: agriculture. SUBSTANCE: the process comprises feeding 27.8-31.3 % spent drilling mud, 40.6-45.3 % hydrolysis lignin and up to 100% water into a concrete stirrer and stirring the whole mixture till a homogeneous mass is formed. Then at least 24 hours later, the composition is applied to soil at an application rate of 1-2 t/hr. In this case, the content of water resistant components increases and the filtration coefficient becomes lower. EFFECT: improved properties of the composition. 5 tbl
