Abstract:

Soil application of sewage sludge, urban compost and poultry manure in vegetable production offers an alternative technique for its disposal and management. The present study was taken up to evaluate the effect of sewage sludge, urban compost and poultry manure on heavy metal content of soil in brinjal-cauliflower cropping sequence. The three organic manures were applied each at 2.5and 5.0 t/ha, 100% RDF and combination of fertilizer levels (75% RDF) with manures at different levels and a control treatment, arranged in a randomized block design (RBD) with three replicates. Addition of manures with fertilizers resulted in increased DTPA extractable micronutrient content of the soil in both the seasons and residual effect of previous season. Among the treatments application of poultry manure @ 5.0 t ha-1+75%RDF increased the DTPA extractable micronutrient (Fe, Mn and Zn) content in soils. There was a significant build-up of Cu, Cd, Ni, Cr and Pb in soil at sewage sludge @ 5.0 t ha-1+75% RDF application. All the heavy metal concentrations in soil were below the safe limits.
