Tannery effluent poses significant risks to soil health, primarily through contamination with heavy metals like chromium, sulphides, and persistent organic pollutants (POPs). These toxic substances inhibit microbial activity, reducing nutrient cycling matter decomposition essential for fertility. Beneficial microorganisms, including nitrogen-fixing bacteria, are particularly affected, leading altered communities dominated by less advantageous, metal-tolerant species. Accumulation of POPs disrupts enzymatic activities, interferes plant root growth, complicates remediation efforts due pollutant migration groundwater potential entry into the food chain. Prolonged exposure such contaminants diminishes fertility, reduces resilience, ecosystem services, posing threats agricultural productivity environmental health. This review was aimed outline what made bioremediation a superior treatment technology among other methods used in remediating tannery contaminated soil.

Improving food grain production by enhancing plant nutrient availability is critical for meeting future production. In this line, degraded soils may have the potential to meet demand of population. However, key challenge excessive concentration salts. It adversely mediates soil fertility parameters, physical properties and enzymatic activities. Addition organic substances, such as farm yard manure (FYM) pressmud (PM), improve health parameters. An incubation experiment was conducted with graded application FYM (0, 2.5, 5 10 t/ha) PM monitor release pattern PM; its effect on physico-chemical The results showed that pH EC were reduced after one year period. also observed available nutrients like N, P, K, S activities reported highest in treatment (each applied over control. findings study suggested amendments can fertility, mitigate salt ion toxicity, enhance potential, particularly arid semi-arid soils.
