Susan George (1976) states: "The food crisis became the center of world attention in 1974." In calculating the lack of food, the maximum predominance is in sub-Saharan Africa, where one in three people go hungry, but the ultimate numbers are in South and East Asia. For them, availability of food is a bigger problem than food supply (FAO, 2011). This figure illustrates the ratio of people suffering from hunger in the world (FAO, 2011). In this topic, we will discuss the situation in Sub-Saharan Africa, particularly South Africa. South Africa comprises thirteen countries, including the islands (The National English Literary Museum, 2010). Among the many reasons for this, poor harvests are the main cause of declining food supplies in South Africa, due to a lack of nutrients in the soil. In order to alleviate the hunger problem in South Africa, the government uses many solutions, such as replenishing soil fertility (Sanchez 2002, 2019). For the purposes of this project: the variety of soil nutrients and methods of its replenishment will be discussed. This project will demonstrate that soil improvement with different types of nutrients is an effective solution and will evaluate it using three criteria: profitability, costs and time. There are many reasons for soil nutrient depletion in South Africa, but there are a few ways to achieve this. and these are: phosphorus replenishment, nitrogen replenishment and the use of animal manure. Discussions of these three methods are followed in the next three paragraphs. Sanchez et al. (1997, 12) state that phosphorus is one of the main elements of soil productivity in South Africa. The work done by phosphorus is complex, due to its chemical and biological pathway, and has long-lasting properties...... middle of paper ......forestry.org/units/library/books/pdfs/ 91_Replenishing_soil_fertility_in_africa.pdfBekunda, Mateete, André Bationo, Henry Ssali. 1997.
