METHOD FOR WASHING SAPROPEL ONTO FIELDS Russian patent published in 1994 - IPC

FIELD: agricultural land reclamation. SUBSTANCE: sapropel is washed up into check plot on ridgeless furrows cut on moistened and compacted ground and alternating with strips of deeply loosened ground. Sapropel pulp is dehydrated through straw filters combined with water runoffs in side guard ridges. The number of filters increases from upper part of check plot to discharge point of filtered water. This increases density of furrow soil, washout resistance of each type of cohesive soil thus increasing initial specific consumption of pulp ad raising efficiency of sapropel wash-up along with reducing the width of washed-up plot. EFFECT: higher efficiency of method. 2 dwg
