Answer to Question #263973 in History for Jaydells

Question

With examples, examine the appropriateness of composting as a technology in Africa agriculture

Answer 1

Composting is the biological decomposition of organic materials by microorganisms under controlled, aerobic conditions to a relatively stable humus-like material. Composting is an aerobic method of decomposing organic solid wastes. It can therefore be used to recycle organic material. Compost is used to improve soil structure through the addition of carbon and provide plant nutrients. In addition to being a source of plant nutrients such as nitrogen (N), phosphorus (P), and potassium (K), it improves the Physico-chemical and biological properties of the soil.

Composting is a strategic technology that has long been applied in the sustainability of African agricultural activities. The use of plant materials and manure dates back to the beginning of agriculture in Africa. However, this method has advanced well with the introduction of composting technology used to improve soil fertility, increase plant growth, conserve water, and provide nutrients to the plants using the organic form. The appropriateness of composting as a technology used in African agriculture is that it is a natural biodegradation process that turns the remains of plants, manure, and kitchen waste into nutrients that are rich for plant growth. Another example is that composting technology sustains agricultural activities by solving essential issues like the disposal of livestock waste and crop residues. Moreover, composting technology is essential because it eliminates soil, water, and air pollution by converting organic waste into compost. Moreover, with the increased levels of poverty in the African countries, this technology is appropriate in that it has been used to replace fertilizers and helps to improve the properties of soil and plant growth.

Agriculture in African countries has been of great benefits in terms of increase in crop productivity and cost-effectiveness. Compost increased the capacity of the soil to hold water. This means that it is effective when used in the dry parts of Africa. By increasing productivity of idle land, agriculture output increases leading to more exports for the African countries. In Ghana, wastes from goats are being used as manure in farms. This has greatly reduced the use of pesticides and fertilizers in agriculture. Similar use of compost has been experienced in Kenya using households waste, vegetables from markets, and avocado waste. In Tanzania, waste from crops and manure is used as food for fish. If handled well, much benefit can be achieved from organic waste.
