The accumulation of Cr in soil is a major concern because of its possible phytotoxicity or increased movement of metals into food chain and the potential for surface and ground water contamination. Excessive metal accumulation in contaminated soil can result in decrease in soil microbiological activities, soil fertility and overall soil quality which may lead to reduction in yield. With Three levels of chromium concentration (0, 25, 50 ppm) with and without organic amendments like Biochar, Poultry Manure and sewage sludge a pot culture experiment was conducted taking paddy as a test crop with an objective to study the remediation effect of these organic amendment on Chromium toxicity by assessing different growth parameters and yield attributes of Rice plant. | Remediation of chromium toxicity by biochar, poultry manure and sewage sludge in rice (Oryza sativa) crop
