WebSoil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. It can also come about through artificial processes such as irrigation and road salt. WebNitrate leaching is the downward movement of nitrate with water that drains through the soil. Loss by leaching implies that nitrate is irreversibly lost for crop uptake by moving below the deepest zone of water uptake by roots. The amount of nitrate leached in any situation de-pends on soil properties,amount of water draining
