Soil degradation and low crop productivity are main problems in sub-Saharan Africa, and Kenya is not an exception. Kenya has a wide variety of soil types, from low to high fertility; however, most of these soils face problems such as acidity, nutrient depletion and poor drainage. Moreover, agronomic practices are often not the best, which accelerates soil nutrient mining and lowers crop productivity even more.
How to address soil degradation and increase productivity are the main questions that face Kenyan farmers. Organic agriculture is an option to revert environmental degradation, while achieving produce in a sustainable way. However, long-term benefits or drawbacks of organic agriculture in Kenya have not yet been determined in a systematic manner.
