Abstract
Compost derived out of solid wastes generated during 1997-99 in Kolkata was characterized. The compost samples were dark-brown, of earthy odour, neutral in reaction and had high water-holding capacity, organic C, total P and K contents but not total N. Cation-exchange capacity of the compost samples exceeded the proposed limit of 60 cmol (p+)/kg on ash-free basis. All the samples were sufficiently humified and had high microbial biomass. Those were free from E. coli and Salmonella. Physico-chemical and microbial parameters indicated maturity and stability of the product deemed necessary for crop production. Total and bioavailable forms of heavy metals in the samples warrant attention.
