Gettysburg, PA | Kirk, I'm sure that is part of the response we see, but, I just wouldn't have believed that the oats tied up that much N to result in such a poor yeild? With the added poultry manure, I would have expected the soil critters to be able to break down that residue much quicker and release the tied up N before the end of the corn season. But, I will add that the soil in the oats really became dry and hard!! When nitrogen tests were done in July the probe could only get about 6 inches into the ground (this isn't long term no-till field) while in any of the other covers it went in 12 inches quite easy. So with those kind of conditions the bugs and bacteria probably weren't feeding very well anyway. But, again the non cover cropped wheat fallow part of the field did much, much better and the soil conditions were very similar? | |
