The recommended doses of nitrogen (N), phosphorus (P), potassium (K), sulphur (S) and micronutrients on this page have been compiled from publicly available resources of government agencies and agricultural universities. The Triple Super Phosphate (TSP) dosage has been calculated by our in-house agronomy team based on the recommended phosphorus (P) requirement. This information is a general guide and may vary with soil type, soil test results, crop variety, climate and local conditions. For best results, please adapt the recommendations for fulfilling the nutrient requirements (N,P,K, S and micronutrients) according to your soil, crop and local conditions with the help of an agronomist/agri-extension officer/agricultural expert.
