Answer:
Soil is a medium of plant growth being a mixture of minerals gases and organisms. Details related to the soils are described in details below.
Explanation:
As soil taxonomy is divided into 14 parts it becomes necessary in understanding their importance. Given by USDA.
- Alfisol: soil with aluminum and iron, and have horizons of clay accumulation. Andisoil: Volcanic ash soils, covering only one percent of the globe and highly fertile. Arid soil: Dry soils formed under desert conditions, covering nearly 12% of the earth's surface. Entisol: Recently developed soils have least developed horizons. Sediments of sand clay and volcanic ash.
- Gelisoil: Permafrost soils with permanent, constitute 9% of soils worldwide. Histosol: Organic soils formed by bogs. Inceptisols: Young soils constitute about 15% of worldwide. Spordo soils: Acidic soils with the organic layer. soils of coniferous and deciduous.
- Utisoils: Acidic soils of humid tropics and subtropics. Vertisols: Inverted soils. Oxisols: Heavily weathered and rich in iron.
- The sandy soils tend to have a higher bulk density than clayey or loamy soils. As they have higher critical density and root penetration. Thus plants can tolerate a higher density in sandy soil as compared to that of the clayed soil.
