Calculate exact NPK fertilizer needs for your crops across all 54 African countries. Get local product recommendations, prices, and subsidy information.
AfroTools' Fertilizer Calculator helps African farmers determine exactly how much NPK fertilizer their crops need. Each country tool uses locally available fertilizer products with current market prices and subsidy information where applicable.
Select your crop, enter your farm size and target yield. The calculator computes nitrogen, phosphorus, and potassium requirements based on crop nutrient uptake rates, then converts these into specific fertilizer products available in your country. Optional soil test inputs provide even more accurate recommendations.
NPK stands for Nitrogen (N), Phosphorus (P), and Potassium (K) \u2014 the three primary nutrients plants need. Nitrogen promotes leafy growth, phosphorus supports roots and flowering, and potassium strengthens overall plant health. Getting the right balance for your specific crop is key to maximizing yields while minimizing waste.
A soil test is recommended but not required. Without one, the calculator uses standard estimates for your region. With soil test results, recommendations become much more precise \u2014 potentially saving you money on fertilizer you don\u2019t need.
Yes. For countries with active fertilizer subsidy programs, the calculator shows both market prices and subsidized prices, along with program details and eligibility requirements.
