Conservation Agriculture and soil fertility management Part 1

Conservation Agriculture and soil fertility management Livestock

Theoretical principles and practices In South Africa, crop production systems based on intensive and continuous soil tillage have led to excessively high soil degradation rates with a reduction in natural soil fertility in areas under grain production. It also results in the consistent recommendation of the use of huge quantities of chemical fertilizers that are…
