Map of the dominant soil types of Nigeria. The soils in the northern region of Nigeria are categorized as reddish brown or brown soils of the semi-arid and Arid Regions. They are also known as tropical Ferruginous Soil and are considered to be comparable to Ferric Luvisols. These are sandy soils that are made up of about 85% sand.
The drill scene in the village. Groundwater in Nigeria is widely used for domestic, agricultural, and industrial supplies. The Joint Monitoring Programme for Water Supply and Sanitation estimate that in 2018 60% of the total population were dependent on groundwater point sources for their main drinking water source: 73% in rural areas and 45% in urban areas.

[7] [8] [9] Microorganisms (soil microbes) are involved in biogeochemical cycles in the soil which helps in fixing nutrients, such as nitrogen, phosphorus and sulphur in the soil (environment). [10] As a consequence of the quantitative magnitude of microbial life (calculated as 5.0 × 10 30 cells, [ 11 ] [ 12 ] ) microbes, by virtue of their ...
It is more difficult to raise or maintain levels of biological activity and soil organic matter when human activity is present. It takes consistent work to maintain soil organic matter, including crop rotation and the return of organic resources. Due to quick decomposition, well-aerated soils and warm, humid climates present special challenges.
Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. [1] It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans.
Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...
Soil degradation: Bush burning destroys the organic matter and nutrients in the soil, making it less fertile and productive. It also reduces the soil moisture and increases the soil temperature, making it more susceptible to erosion and compaction. It also alters the soil pH and microbial activity, affecting the soil quality and health. [3] [4] [6]
In 2011, Nigeria commissioned a report from the United Nations on the impact of oil extraction in the delta area of 'Ogoniland'. [45] The report found severe soil ground and tapwater contamination, destruction of mangroves, and "that institutional control measures in place both in the oil industry and the Government were not implemented ...
