A corn field somewhere on planet vulcan
Anyone done a yield comparison of uan topdress vs urea topdress done at pre tassel? - In my case have some corn done 2 weeks pre tassel and the color on the uan corn is the darkest green and the urea is not, rain came immediately after the urea so none lost. Found this last year as well - ??
