As most grain producers realize, we are heading into an environment of lower commodity prices, tighter profits; and this can lead to tighter wallets. One might ask, should the lower prices affect the fertility programs? The short answer is “yes” but how and to what degree? Whether we are producing $4 or $7 corn the crop still requires the same nitrogen (0.67-1.12 lbs /bu) , phosphorus (0.35-0.58 lbs/bu) and potash (0.24-0.43lbs) not to mention the micros. Limiting the availability of any one of these macro or micro nutrients can and usually will limit yield. How can a fertility program be sliced without affecting yields?
