Five years to a ban on manure application to soybeans
November 16, 2006

Iowa's Environmental Protection Commission has decided to impose new limits on the application of liquid manure to fields used to raise soybeans, with a full ban intended in about five years. Part of what's peculiar about the rule is that most of the smarter farmers realize that nitrogen-rich manure doesn't do much good for soybeans anyway, since beans are nitrogen-fixing plants. In many cases, the only reason manure is applied to soybean fields is because the farmer applied it before deciding whether that field would go to soybeans or corn in the following year.
