Explain the causes of soil acidity

WebSoil pH plays an important role in availability of nutrients essential for plant growth. In general, optimum availability occurs between a soil pH of 6.0 and 7.0 (Brady, 1990 ). Low pH results in lower rates of N mineralization, a process dependent on active, viable microbial populations in the soil. WebMar 26, 2014 · Soil pollution is defined as the build-up in soils of persistent toxic compounds, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health [ 1 ]. Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface.
