3 Major Types of Weathering and Soil Profile

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 wind, water, temperature and sunshine. It is also due to…

4 Major Elements in the Components of Soil

There are four main components of soil, which are: those resulting from the breakdown of rocks, organic matter, water and air. In addition, soil contains microbes or micro-organisms. Soil is made up of inorganic particles of different sizes such as stones, sand, silt and clay. Each of these is surrounded by microscopic film of moisture in which nutrients are dissolved. These particles aggregate…

Soil pH | SOIL ACIDITY AND ALKALINITY

 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 pH REACTION Soil pH is a measure of the acidity vs the alkalinity…

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 requirement of the crop plants in question. Factors of Soil fertility A.     Factors contributing…

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 be defined as the science and art of looking after the land in such a way that soil is retained in one place…

Soil pH | Soil Acidity and Alkalinity

Soil pH is the degree of acidity or alkalinity of a soil. 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 pH…
