tailieunhanh - Assessment of heavy metals on fortified municipal solid waste compost treated soils (Typic Ustropet) in Okra (Abelmoschus esculentus (L.) Moench) - Onion (Allium cepa L.) cropping sequence

From the experimental results emanated from first crop of okra, among the Municipal Solid Waste Compost (MSWC) treatments application of 100% Rec. NK + FMSWC with poultry manure 10% (9:1) at 5 t ha-1 along with phosphorus (M4P1) recorded lowest Pb, Ni and Cd contents at harvest stage in soil which was on par with the treatment, 100% Rec. NK + FMSWC with SSP at 5 t ha-1 along with phosphorus (M7P1) which was significantly lower than that of other treatments with FMSWC at higher doses. Onion crop was raised as succeeding crop to study the residual effect of municipal solid waste compost. From the experimental results, the application of 100% Rec. NK + FMSWC with poultry manure 10% (9:1) at 5 t ha-1 with phosphorus (60 kg ha-1 ) (M4P1) registered lowest heavy metal Pb, Ni and Cd contents in soil which was on par with the treatment, 100% Rec. NK + FMSWC with SSP at 5 t ha-1 along with phosphorus (60 kg ha-1 ) (M7P1) as compared to other treatments with FMSWC higher doses. With regard to heavy metals accumulation in soil, plant, fruit and bulb samples is below the permissible limits as prescribed by Indian standards (2013) and World Health Organization (2007). | Assessment of heavy metals on fortified municipal solid waste compost treated soils Typic Ustropet in Okra Abelmoschus esculentus L.
