Susan George (1976) states “The food crisis became the focus of worldwide attention in 1974.” By calculating lack of food, the maximum dominance is in sub-Saharan Africa, there is one in every three persons is hunger, but the ultimate amounts are in South and East Asia. Availability of food is the greater problem for them, than the supply of food (FAO, 2011). This figure illustrates the ratio of hunger people over the world (FAO, 2011). In this topic, we are going to discuss the situation in Sub-Saharan Africa especially South Africa. South Africa consists of thirteen countries, including the islands (The National English Literary Museum, 2010). Amongst the many reasons for this situation, bad harvest is the main cause of decreasing food storages in South Africa which is due to is the shortage of nutrients in the soil. In order to alleviate the hunger problem in South Africa, the government uses many solutions, such as replenishment of soil fertility (Sanchez 2002, 2019). For the purpose of this project: variety of soil nutrients and methods of its replenishment will be discussed. This project will argue that improvement of soil by different kinds of nutrients is successful solution and will evaluate it using three criteria: profitability, costs and time. There are many reasons of nutrient depletion of soil in South Africa, but a few ways to get success and they are: phosphorus replenishment, nitrogen replenishment and use of animal manures. Discuss of these three ways are followed in next three paragraphs. Sanchez et Al. (1997, 12) state that phosphorus is one of the most main segments of soil productivity in South Africa. Work done by phosphorus is complex, because of chemical and biological route, and has enduring propert... ... middle of paper ... ...forestry.org/units/library/books/pdfs/91_Replenishing_soil_fertility_in_africa.pdf Bekunda, Mateete, Andre Bationo, Henry Ssali. 1997.
