Calculating Fertilizer Rates from Nutrient Recommendations Soil test recommendations are given in lb/ac or kg/ha of nutrients. To determine the fertilizer rate for a particular nutrient, multiply the rate of the desired nutrient by 100 and divide by the percentage of the nutrient in the fertilizer.
.
Likewise, how do you calculate fertilizer cost per unit?
First, calculate the standard cost per lb of P2O5 and K2O:
- Pounds of P2O5 per ton of 0-46-0 = 2000 x 46% = 920 lbs of P2O5 Cost per lb P2O5 = $260 ÷ 920 lbs P2O5 = 28 cents per lb P2O5
- Pounds of K2O per ton of 0-0-60 = 2000 x 60% = 1200 lbs of K2O. Cost per lb K2O = $175 ÷ 1200 lbs K2O = 15 cents per lb K2O.
Similarly, how much is a bag of fertilizer? Lawn Fertilizer Average Costs A bag of lawn fertilizer might cost $6 to $26 depending on the pounds per bag and the fertilizer nutrient profile.
Correspondingly, how do you calculate fertilizer per acre?

(Nutrient rate per acre ÷ fertilizer nutrient proportion = pounds of fertilizer needed to apply per acre.)
How many units is 28?
