    EDAPHIC FACTORS AFFECTING AGRICULTURAL PRODUCTION

    1) Soil pH It affects the growth of plants. It also affects the availability of soil nutrients to plants. It affects the presence of soil microorganisms. It causes toxicity to plants and animals in the soil.   2) Soil Texture It determines the type of soil in an area. It determines the level of soil fertility. It determines the type of crops to be grown. It affects the level of leaching and erosion.   3) Soil Structure It determines the fertility of the soil. It determines the water-retaining capacity of the soil. It determines the level of soil organisms. It determines the level of soil aeration and percolation.   4)…

    SOIL EROSION AND DESERT ENCROACHMENT

    Soil erosion is defined as the removal of the top layer of the soil through various agents like water and wind.   Types of Soil Erosion There are two main types of soil erosion. These are: Soil Erosion Caused by Water: This is the type of erosion in which the top soil is washed and carried away by running water. The types or kinds of soil erosion caused by water include: Rill erosion: This is caused by the accumulation and running away of water which carves narrow channels on the soil through which water flows. Sheet erosion: This is the removal of a uniform depth of soil over an extensive…

    EROSION CONTROL TECHNIQUES AND WEATHER INFORMATION UTILIZATION

    Erosion control techniques are fundamental for the protection of water quality. Soil stabilization and erosion control practices are needed and should be used in areas where soil is exposed and natural vegetation is inadequate. Bare ground should be covered, typically with grass seed and some form of matting or mulch. This will help prevent erosion and subsequent movement of sediment into streams, lakes and wetlands. Erosion control measures need to be implemented immediately following construction and every time an area is disturbed. Soil erosion can be controlled by adopting land management practices and also by changing the pattern of some human activities which accelerate soil erosion. Erosion control is as…
