WebNutrients content I’d like to start with a basic explanation about the NPK nutrients and their percentages (%) in fertilizer formulae. Fertilizer's formula usually refers to the content of nutrient in their oxide forms (N-P2O5-K2O). In Scandinavia, Australia and South Africa it is more common to refer to elemental forms (N-P-K). Web26 mrt. 2002 · The phosphorus and potassium share of the fertilizer product cost will be calculated using standard costs per lb for P 2 O 5 and K 2 O, calculated from the single nutrient sources 0-46-0 and 0-0-60. This example also illustrates how to calculate nutrient price per pound when the product is priced on a per gallon basis, not on a per ton basis.

For example, a 5 lb. bag of 10-5-5 fertilizer contains 0.5 lbs. of N, 0.25 lb. of P2O5 , and 0.25 lb. of K2O. WebThe popularity of TSP has declined because the total nutrient content (N + P2O5) is lower than ammonium phosphate fertilizers such as monoammonium phosphate, which by comparison contains 11% N and 52% P2O5. Costs of producing TSP can be higher than ammonium phosphates, making the economics for TSP less favourable in some situations. exemption on tax meaning
