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. WebSoil is the loose surface material that covers most land. It consists of inorganic particles and organic matter. Soil provides the structural support to plants used in agriculture and is also their source of water and nutrients. Soils vary greatly in their chemical and physical properties. Processes such as leaching, weathering and microbial ... WebA soil moisture content of 150 mm/m. The soil moisture content can also be expressed in percent of volume. In the example above, 1 m 3 of soil (e.g. with a depth of 1 m, and a surface area of 1 m 2) contains 0.150 m 3 of water (e.g. with a depth of 150 mm = 0.150 m and a surface area of 1 m 2 ).

WebFor all lysimeters, Ca and Mg leached more rapidly than K. Annual losses over all treatments, 1976 through 1980, averaged 387 kg Ca ha −1, 118 kg Mg ha −1, and 44 kg K ha −1. Such leaching would eventually lead to enrichment of local soils with K relative to Mg and Ca. WebA leaching index or moisture index is calculated by subtracting evapotranspiration from precipitation. This index is an indicator of average soil moisture conditions. The greater the index, the more soil moisture is present. Higher soil moisture increases chemical weathering and moves minerals, such as bases, deeper into the soil profile.
