[QUOTE="SRBeef, post: 767497, member: 7509"] I agree with TPP, the P & K in the 15-15-15 applied at this time of year would not be likely to benefit this years corn crop. Yellow slow growing corn can be a sign of N deficiency, waterlogged roots or too cool temperastures or a combination of the above. At this time of year in Ontario and seeing as you are going to use it for silage I would just hold tight and not apply any more fertilizer. Even if it is N deficiency, broadcasting dry Urea on the surface at 2 ft height may or may not help the corn and getting urea in the whorl may actually damage your corn. As mentioned above, after harvesting silage, do soil tests in the fall and re evaluate your fertilizer program for next year. A split application is the most efficient way to apply N. Have your soil test also include micros such as sulphur, boron, etc Also check the pH which has a dramatic effect on corn growth. If lime is needed apply the finest grind you can get this fall. Good Luck. Jim [/QUOTE]
