Fertilizer Blend Calculator
Calculate how many pounds of fertilizer are needed to meet specific nutrient targets.
Inputs
How It Works
Fertilizer Required (lbs/acre) =
Nutrient Target ÷ Nutrient Percentage
Nutrient percentage must be converted to decimal.

FAQ
How does fertilizer analysis work?
Fertilizer analysis lists the percentage of nutrients such as nitrogen (N), phosphorus (P₂O₅), and potassium (K₂O).
Can this calculator be used for N, P, and K?
Yes. Enter the nutrient percentage for the nutrient being targeted.
Why divide by percentage?
Because only a portion of the fertilizer product contains the target nutrient.
Understanding Fertilizer Blending and Nutrient Targets
Fertilizer blending allows producers to meet precise nutrient targets for crops based on soil test recommendations and yield goals. Rather than applying fixed rates, growers calculate the exact pounds of fertilizer required to supply specific amounts of nitrogen, phosphorus, or potassium.
Because fertilizer products contain nutrients as a percentage of total weight, calculating required application rate involves dividing the nutrient target by the nutrient concentration. This ensures accurate application rates and prevents under- or over-application.
Using a fertilizer blend calculator improves nutrient efficiency, reduces input waste, and enhances profitability in precision farming systems. Proper blending supports optimal crop performance while promoting responsible nutrient management practices.
