The Implication of Soil Acidity and Management Options for Sustainable Crop Production in Africa

Abstract

Acidic soils are widespread in Africa and present a major crop production challenge in a region faced with multiple climatic and soil constraints. Effective management recommendations in line with the 4Rs of lime management (Right Source, Rate, Time, and Place) are necessary for optimizing the agronomic and economic benefits of lime at the farm-level. In addition, policies and incentives are needed to develop viable lime supply chains.
