Fertilizer Requirement Calculator
Calculate fertilizer quantity from recommended N, P₂O₅ and K₂O rates.
Recommended Nutrient Dose
Fertilizer Sources
Calculation basis:
fertilizer quantity = nutrient requirement ÷ nutrient fraction.
When DAP is selected, nitrogen supplied by DAP is automatically
deducted before calculating the urea requirement.
Typical nutrient grades used: Urea = 46% N, DAP = 18% N + 46% P₂O₅, SSP = 16% P₂O₅, and MOP = 60% K₂O.
Use nutrient recommendations appropriate for the crop, soil, region and local agronomic guidance. This calculator converts a recommended nutrient dose into fertilizer quantity; it does not prescribe a fertilizer dose.
