Soil amendment with distillery effluent for wheat and rice cultivation

Distillery effluent contains a considerable amount of plant nutrients. In a field study soil amendment with diluted post methanation distillery efflue nt increased the yield of wheat and rice grown in sequence. Organic carbon and available potassium content of post harvest soils were also increased. Saturated hydraulic conductivity, bulk density and volumetric water content of the soils improved with effluent application. There was no change in pH after harvest of wheat and rice. The study showed that the effluent could be used as soil amendment. However, the EC of soil also increased indicatin g the possibility of salinity development in the long run with higher level s of effluent application.
