Crop Nutrition Section



The crop nutrition section conducts research on crop nutrition and soil management aimed at enhancing productivity of soils and crops. Such research includes studies on crop production ,soil fertility management, generation of techniques for improving productivity of soils and crops and soil-water-plant relationships under irrigated and rain fed conditions

Collaborative research work is also carried out with public and private sector organisations within and outside Zimbabwe. These include the local universities, private companies, NGOs and international organisations such as the International Atomic Energy Agency.


The section also offers fertilizer and lime recommendations to farmers. Diagnosis of plant nutrient deficiencies. Advice is given to individual and organisations on crop nutrition, soil fertility management and various soil-related problems. The section also disseminates soils information to various user groups within Zimbabwe.
