Soil is the unconsolidated (or loose) covering find rocks particles that covers the surface of the Earth. It consists of weathered particles of rocks brought down by the agents of erosion — water, wind and glaciers. It also consists of decaying organic matter (humus) and minerals.
Soil Verizon colour, texture, fertility and content. The type of landforms and the nature of the parent rock determine the type of soil. Fertility of the soil refers to its ability to produce vigorous growth in plants. The right mix of minerals and organic matter, with the ability to retain the correct amount of moisture, determine the fertility of the soil.
Soil forms very slowly— that time taken can range from 200 to several thousand years.
