Use of domestic sewage effluent for sustainable production of vegetable in Kashmir valley
Trace metals in discrete portions of knoll kohl were evaluated along with chemical composition of sewage effluent, irrigation water, and soil. High nutrients, Fe and Mn levels were noticed in the sewage effluent, whereas irrigation water showed recommended norms. Knoll kohl grown on sewage-irrigated soil accumulated sufficiently good amount of trace metals available to consumers. This study also suggests that the use of domestic effluent for the production of vegetables gives benefits of valuable source of nutrients, organic matters and less expensive irrigation water. Besides, it may offer cost-effective techniques of sewage effluents disposal for sustainable agriculture and environmental hygiene.
