Organic cotton in Tanzania is promoted by BioSustain through several principles that enrich soil health and biodiversity. The main strategies deployed in organic cotton production systems are crop rotation with legumes and maize, following a three-year rotation. Legumes used include mung beans, green grams & groundnuts; minimum tillage, planting on ridges, intercropping with cover crops, contour planting and fallows; application of liquid manures and cow urine; seed treatment with cow dung; composting; moisture conservation through tied ridges, mulching and potholing; use of molasses traps; pest scouting and biopesticide preparation using neem leaves and Solanum incanum.
