Soil quality decline is one of the main causes of land degradation and is considered to be responsible for 84% of the ever diminishing acreage. Year after year, huge acres of land lost due to soil erosion, contamination and pollution.
If soil pollution is not controlled, it can have adverse effects on the ecological balance and health of living organisms. These effects include increased soil erosion; creation of toxic dust; loss of nutrients in soil; reduced soil fertility; alteration in soil structure; and increase in soil salinity.
