Price Per Pound of Nitrogen, Phosphorus, and Sulphur in a 11-40.5-0-16.6 Fertilizer Blend

Lethbridge, AB|Dec 20, 2023
I have a 11-40.5-0-16.6 fertilizer blend.
Rate is 54.3lbs/acre.
It costs $1,043.60/mt or $25.71/ac.
What’s the price per pound for nitrogen, phosphorus, and sulphur?

Answers (5):
You will need to place a value on the P2O5 and the SO4 in the product, then you can determine the value of the remaining nitrogen in the product.
It would be interesting to know what your blend is made up of, and what you paid for individual products. It almost looks like a 40 Rock or MESZ product enriched with Super S or an elemental product.
Based on current Urea and MAP prices, the N would be around $0.65/lb and P would be around $0.80/lbs
Where’s your potassium and why only 11 lbs of N? Also what products are you using? Different products have different efficiencies depending on what you have in your soils, your soil types and your products this could be a wildly inefficient blend or more or less sufficient.
I would steer away from this blend. Most of the nitrogen will leach out. Phos will tie up, not enough sulfur to make a difference on your farm. Better off spending the $25.71/acre in season.
