NE IL | A lot of people use it here because we are so close to Chicago. It gets spread and chiseled in after wheat and the corn the following year always looks great, some of the greenest corn you will ever see. Just to be safe we usually add 100 lbs. of N to it the next spring even though they say they apply it at a high enough rate to meet the N needs for 200 bu. corn. It will cover your phosphate needs for 5 - 10 years and its all free. Only part that costs is you have to grow wheat so they can have time to apply it in the summer or fall. There is a certain distance they must keep it from creeks and wells so on some fields you have to apply more nitrogen in certain spots with anhydrous or 28 in the spring. Some say there are heavy metals in it and I'm sure there are trace amounts but spread out over all that acreage I don't think it poses any threat. It really builds the organic matter, it's especially noticeable on the clay hills. I think it's a very good product and using it on cropland is as "green" as you can get. It seems like the only people who complain about it are the tree hugging environmentalists when really it's recycling and improving the soil which you would think they would be all for. It's one of the few benefits of farming close to a big city. | |
