This is highly misinformed. Corn doesn't 'need' any supplemental fertilizer (and was grown without much for centuries), we choose to do it because it's more profitable. Soybeans, being a legume, make their own nitrogen. So you comment is wildly misleading making people believe people are putting 300 pounds of nitrogen per acre
- sokoloff 5y ago"Needs" might be slightly too strong a word in terms of supplemental nitrogen for corn, but note that the corn is going to take nitrogen either way, whether naturally provided or supplemented. (Corn is a grass with very tasty seeds.) However, when the article makes comparisons to what farmers are actually doing, I think it's fair game to bring in data around what farmers are actually doing.
- kickout 5y agoNo farmer is applying nitrogen to soybeans. They fix their own nitrogen, and generally add nitrogen to the system. Any plant is going to take nutrients (native or otherwise) from the system. Just because ornamental species don't have a commercial value doesn't mean they aren't extracting nutrients I am very familiar with corn being a grass. Although its seed are very much not tasty unless they happen to have a well known sucrose mutation.
