Sugarcane Nutrition and Fertilizer Use in South Africa

In South Africa during the past four decades considerable research has taken place on the nutrient requirements of sugarcane. Consequently marked changes have occurred in patterns of fertilizer use. The value of N, P and K fertil~zers for cane production is reviewed using field experimental data. Correlations established between soil and leaf analysis and crop responses to various nutrients are discussed. Fertilizer recommendations based on soil and leaf analyses have provided a useful guide for determining the nutrient requirements of cane. Several soil factors affecting plant nutrient availability will make it necessary to revise periodically the current system of recommendations.
