A consultant (salesman) is telling me that I should put apply 3.75 gallons per acre of a liquid 11 0 1 fertilizer instead of 300 pounds per acre of a granular 13 13 13. My calculations say that this would equate to around 5 pounds of nitrogen per acre of the liquid vs 39 pounds of the granular, not to mention the huge difference in the P and K. Am I missing something.
I think your math is correct. 3.75 gallons/acre of anything is not much. Heck my sprayer has a 3.8 GPM pump on it, so I'd be done with an acre in one minute! I suppose you could dilute, but still. Granular is obviously water soluble when it rains, its just a more potent way of applying fertilizer.
