There was significant difference in fat content of poor soil treated with different organic amendments.
Kumar and Chopra (2013b) found higher organic content in the soil treated with sewage sludge.
The soil treated fertility was evaluated to evaluate the OMW spreading phytotoxicity potential.
Likewise, reproduction of M. arenaria was greater in soil treated with nematicides.
The soil treated with chemical fertilizers resulted in an increase of Cr, Pb, Cd, Cu, Ni and Sb while there was an increase in the concentrations of Zn and Hg in the soil treated with urine.
Three sets of pot soil were used for chemical analysis, namely untreated or control (devoid of bacterial suspension and feathers), soil treated with bacterial suspension and soil treated with both bacterial suspension and feathers.
The leaves of S. oleracea harvested from soil treated with chemical fertilizers showed the highest concentration of Zn while the stalks harvested from soil treated with urine showed the least concentration with no significant difference (p < 0.05).
The highest concentration of Ni was present in the roots harvested from soil treated with biosolids while the least concentration was in the stalks harvested from soil treated with urine.
The roots of S. oleracea harvested from soil treated with biosolids showed the highest concentration of Cu while stalks of S. oleracea harvested from soil treated with urine showed the least concentration of Cu.
The highest concentration of Cr was present in the roots of S. oleracea harvested from soil treated with biosolids, whereas the least concentration of Cr was found in the stalks harvested from soil treated with urine.
The pH of the soil treated with both bacterial suspension and feather was found to be slightly increased as compared to control and soil treated with only bacterial suspension due to degradation of feathers.
