Leaching often occurs with soil constituents such as nitrate fertilizers with the result that nitrates end up in potable waters. (Source: PORT).Environmental information systems. Pesticides are frequently leached through the soil by the effect of rain or irrigation water. Pesticide leaching is highest for weakly sorbing and/or persistent compounds, climates with high... The soilleaching potential gives information on the likelihood of a potential pollutant that is applied to the soil surface filtering through the soil and reaching a water course or ground water. Soil can lose essential water-soluble nutrients needed for crop growth due to excessive rain or irrigation. This process is referred to as leaching. SoilLeaching :- Soilleaching is a natural process where excess water (from rain or irrigation) dissolves and carries water-soluble nutrients and other substances out of the topsoil... Soil degradation: Continued leaching can degrade soil structure and organic matter. In extreme cases, surface soils can become acidic or accumulate salts. Leaching of soil. The soil in your garden is like a sponge. When rain falls, the soil near the top absorbs as much as possible, keeping the moisture available to the plants growing there. Soil Characteristics that Affect Leaching. Soil profile in cross-section view.Safety Information on the Label. Hazard – Toxicity – Exposure – Risk Management. The B.C. Soil Leachate Test was developed to best predict the leaching and mobility of pH sensitive substances in various soil pH settings. Defining SoilLeaching in Detail. Soilleaching isn’t simply about water moving through soil. It’s about the dissolution and transport of specific compounds dissolved within that water. As the subterranean water moves in response to gradients of gravitational potential, it carries dissolved substances of many kinds. Leaching is a highly influential soil-forming process. Soilleaching remediation mainly leaches contaminated soil, removes pollutants, and then processes the leachate containing pollutants. Polluted soilleaching: unsaturated conditions and flow rate effects. Eurasian J Soil Sci 6(2):161-167.
