The soil texture triangle is one of the tools that soil scientists use to visualize and understand the meaning of soil texture names. The textural triangle is a diagram which shows how each of these 12 textures is classified based on the percent of sand, silt, and clay in each. Note: these percentages are based on the USDA definition of sand and silt only. Follow these steps to determine the textural class name of your soil sample: 1) Determine the percent sand of your sample and find that number on the bottom of the triangle. Note that the numbers read from right to left, not left to right.
From Wikipedia, the free encyclopedia. Soil conservation is the prevention of soil from erosion or reduced fertility caused by overuse, acidification, salinization or other chemical soil contamination. slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas.A sequel to the deforestation is typically large scale erosion, loss of soil nutrients and sometimes total desertification.oil-conservation farming involves no-till farming, âgreen manuresâ and other soil-enhancing practices. Such farming methods attempt to mimic the biology of virgin land.
