Week 12-Soils and Vegetation
Molic epipedon is on the top part of the chalky white calcic horizon, on a chernozem.
Podzol to Chernozemchange in organic matter
Podzols are typically in coniferous orders, due to the high acidity.
Solonetz does not have a lot of organic matter at the top, and it is indicated by desert
Desertification; when water is dried from land, and often dessication cracks are formed
Salinization occurs when soil is cultivated, heavily grazed, then displays an excess of salt.
Irrigation water evaporates, leaving salt behind, and soils can become sodic. Salts from
weathered parent material will migrate to the surface. In dry environments, there is not enough
precipitation to get rid of the salt, and leaching occurs. As water evaporates, salt remains.
