The purpose of this calculator is two fold:
- Answer the question “If I need 100 lbs./Kg of actual nitrogen (N), how many lbs./Kg of calcium nitrate (or any other source of N) would I need?”
- Answer the question “How much does a lb./Kg of N in calcium nitrate cost when compared to other sources of N?”
Using the fertilizer calculator:
- Select the nutrient, the quantity needed, the units and the compound. Press calculate. The answer will be the amount of total fertilizer needed.
- Input the cost per unit in any currency. The answer will be the cost of the nutrient per lb./Kg.
By repeating the process for other fertilizer compounds you can compare the relative cost of a unit of nutrient.
