“…Due to rising population pressure on limited natural resources, the majority of emerging nations are experiencing water scarcity. By 2050, India will need 333 million tonnes (Mt) of food grain up from 289 Mt presently [ 1 ]. This is a challenging task for academician and policymakers; since, it focuses on the utilization of organic and inorganic soil amendments for long-term agricultural output [ 2 ].…”

“…However, it reduced the population and diversity of microorganisms in the soil. Heavy metal(s) effects on microorganisms and soil enzyme activity are also determined and found that increasing trace metal levels have been reduced the enzymatic activities [ 1 ]. Contamination of lead in soil might be due to use of Pb containing industrial waste, metal industry byproduct waste and also from Pb containing natural ores [ 8 ].…”

Soil fertility management and crop productivity both are inter-related need extensive attention for sustainability. Industries are being built, which over time produces a lot of effluents containing heavy metal(s), which is then dumped on healthy soils and water bodies. Long-term discharge of lead (Pb)-containing wastewater resulted in significant Pb buildup as well as a decrease in soil biological activity. In this experiment, graded dose of Pb, i.e. 0, 100, 150 and 300 mg/kg and pressmud (PM) (0, 2.5, 5, 10 g/kg) were applied to monitor the Pb toxic effect on soil acid and alkaline phosphatase, dehydrogenase activity. Different treatment combinations were formulated and the experiment was conducted in a completely randomized design (CRD) with three replications. In this experiment, spinach crop was used as a test crop. According to the findings, increased Pb levels in the soil lowered dehydrogenase activity (DHA), acid and alkaline phosphatase. The addition of PM enhanced enzymatic activities by decreasing the labile fraction of Pb in the soil. Incorporation of PM improved the soil enzymatic activities as alkaline phosphatase activity > DHA > acid phosphatase activity in the study. This study suggested that the addition of 10 g/kg PM reduced Pb toxicity (contamination level 300 mg/kg) and improved the soil microbial properties in black soil. These findings are very useful for the remediation of Pb contaminated soil with the help of PM, particularly in peri-urban Pb effluent irrigated areas.
