Nevada, Iowa | Late spring nitrate test? Maybe they've perfected it but I couldn't put much faith in it. Used it shortly after it was first "invented" for lack of a better word. Short story, probably 13-14 years ago, test showed almost no N left on the average just prior to mid calf high corn. Side dressed 20 gal UAN with colter injector, left several test strips. Strips yielded equal to slightly more than side dress. Field avg. was in the 180's. Probably unfair but I never used the test again. | |
