The 2014 season has been dry in many places in Kentucky – corn in these areas not growing as well, or looking as good as desired. Many fields are showing less than optimal color and there have been several calls regarding possible need for more N to ‘green things up a bit’. Without evidence of substantial loss of fertilizer N applied earlier, additional N is not a good idea. Extra N (N above and beyond the recommendation) can do more harm than good – especially if the season stays dry.
