Susan George (1976) states: “The food crisis became the center of world attention in 1974”. Factoring in food shortages, the highest prevalence is in sub-Saharan Africa, where one in three people suffer from hunger, but the highest levels are in southern and eastern Asia. For them, food availability is the biggest problem in 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, especially South Africa. South Africa is made up of thirteen countries, including islands (The National English Literary Museum, 2010). Among the many reasons for this situation, crop failure is the main cause of decreasing food supplies in South Africa, due to nutrient deficiencies in the soil. 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 for their replenishment will be discussed. This project will argue that soil improvement with different types of nutrients is a successful solution and will evaluate it using three criteria: profitability, cost and time. There are many reasons for soil nutrient depletion in South Africa, but some ways to achieve success and are: replenishing phosphorus, replenishing nitrogen and using animal manure. The discussion of these three ways will be followed in the next three paragraphs. Sanchez et Al. (1997, 12) state that phosphorus is one of the most important segments of soil productivity in South Africa. The work done by phosphorus is complex, due to the chemical and biological pathway, and has long-lasting properties. , André Bationo, Henry Ssali. 1997. Africa: a review of selected research studies.
