Soil Degradation The damaging process of soil particles being moved and cycled by water or wind is known as erosion. Soil erosion can occur anytime soil is bare or exposed and naturally removed by wind or water. This form of soil degradation is a natural process but it further elevated by human activity. Human disturbances of the soil allow for this process to happen more rapidly under natural conditions. According to the University of Michigan‚ whose geologist conducted a study‚ human actions

Dr. Buchanan-Hamilton in 1807. Laterites are soil types rich in iron and aluminium‚ formed in hot and wet tropical areas. Nearly all laterites are rusty-red because of iron oxides. They develop by intensive and long-lasting weathering of the underlying parent rock. Tropical weathering (laterization) is a prolonged process of chemical weathering which produces a wide variety in the thickness‚ grade‚ chemistry and ore mineralogy of the resulting soils. The majority of the land areas with laterites

Effects of soil ph variation on radish plants growth Background information: the soil ph can have 2 different impacts on the growth of plant roots. First and most important is how it affects the concentration of nutrients present in the soil itself.

While the nature takes from 100 to 400 years to build one centimetre of top soil‚ man can and often does destroy it almost overnight by haphazard land use and improvident husbandry. Irrational methods of cultivation‚ deforestation‚ destruction of natural vegetation due to overgrazing by pasturing animals etc.‚ accelerate denudation. Besides‚ failure of rains‚ floods‚ depopulation and loss of cattle caused by famine and pestilence‚ disturbance caused by war and interference with or change
