SOIL EROSION AND CONSERVATION
 Erosion may mean the wearing or washing away of something. Some of the forces which make soil can also erode the soil so that it is lost to the farmer. Therefore, soil erosion is the removal of top soil by agents of soil erosion, such as rain, wind and flowing water. Soil conservation can

Soil Fertility and its factors
 Soil fertility is defined as the ability of the soil to produce and sustain high crop yields indefinitely. In other words, fertility is a measure of the available nutrients in the soil and the proportion in which they occur. The soil is able to do this only if it can adequately supply the nutritional

SOIL ACIDITY AND ALKALINITY (pH)
 Soil can either be acidic or alkaline depending on the parent material it was made from. The chemical composition affects the acidity or alkalinity of a soil, a factor which influences the availability of nutrients to plants. Soil acidity is also affected by the use of both natural and chemical fertilisers, lime and leaching. SOIL

Weathering Types in the Soil Studies
 Introduction We tend to think of the landscape as unchanging. However, it is slowly and continuously being reshaped. Usually, this reshaping of the landscape results into the production of soils. Soil is formed from the break-down of the parent materials by the process known as weathering. This is the result of climatic factors such as
