Except for the tropical black earths, known locally as Akuse clays, most of these soils are of little importance agriculturally. ecological zone of Ghana. The bulk of production occurs in the savannah regions of Northern Ghana, although cowpea can be grown in all ecological zones of Ghana. The nutrients move from the soil into plants that we eat like tomatoes. Rapid, low-cost technologies generate high-value soils information for planners and . In Africa, though not only in Africa, this type of information is rapidly being lost; much is already lost. 3. To obtain official soil series description, click here. To accomplish this, it was necessary to investigate the forma­ tion and distribution of these soils as determined by such factors as climatic-vegetational conditions, parent rocks, topography, and drainage conditions. 3) Soil fertility decline: the degradation of soil We notice different types of soil based on colour, texture, and composition in different places. Soil type In terms of soil type, it is essential to understand the soil's natural capability to 'repair' or self-structure itself. Some soils, such as sands and silts that are prone to slumping, often benefit from mechanical intervention - even where cover crops are used. Types of Vegetation. '1v800 ~lfiso~s, Fluvents, Inceptisols 750-1'000 Aquents, Aquepts Table 2. This Paper. Generally, higher levels of potassium are needed in soils high in clay and organic matter; lower levels in soils which are sandy and low in organic matter. Below are the various agro ecological zones in Ghana, which includes their specific characteristics; 1. (SOC) along a transect of West African ecosystems sampled across a precipitation gradient on contrasting soil types stretching from Ghana (15°N) to Mali (7°N). It prefers areas with abundant sunlight and regular rainfall (1500 mm to 2500 mm annually). The soil type of each climate zone has been determined. Wind erosion most easily occurs with fine to medium size sand particles. Figure 1. Maize is reasonably tolerant to soil acidity, but if the soil is very acid, liming will .

It is the foundation for the pavement structure. october, 2013 Soil pH is, therefore, described as the "master soil variable" that influences myriads of soil biological, chemical, and physical properties and processes that affect plant growth and biomass yield. Examples of these pollutants are carbon monoxide, carbon dioxide chlorofluorocarbons, ammonia, odour from sewage and garbage, among others. into Ghana and 129, 000 tons were generated in 2009 alone (e-waste Africa Programme, 2011). Subgrade soil or material sometimes is called . This type of African soil occupies a substantial portion of the continent, with most estimates placing it at approximately 26 percent. These classification tests do not yield reproducible results because they are in­ fluenced considerably by methods of preparation and handling of the material (10, 42, 48, 56). This type of soil occupies a number of environments, including dunes, salt pans, and rocky lands. the degradation of soil physicochemical properties (Habtamu, 2011). The high yield of the crop reduces soil nutrients; therefore, it should be grown as the first crop in crop rotation.
