tailieunhanh - Industrial waste composts: Toxicity tests and decomposition studies under laboratory conditions

Enzyme industrial wastes viz. multiple effect evaporator salts, primary sludge, filter press feed were evaluated for their phytotoxic effects under laboratory conditions to understand their potential to use as a nutrient medium for supporting plant growth. It was found that the industrial waste-water extract recorded lower contents of essential nutrients and the presence of heavy metals viz. Ni and Cd. Germination studies revealed the inhibitory effects of industrial waste-water extracts on percentage and rate of seed germination and length of plumule and radicle. | Industrial waste composts Toxicity tests and decomposition studies under laboratory conditions
