Fairbury, NE (Southeast) | Manure, cover crop, no-till, three year rotation CBW or 4 yr CCBW. Beans lower OM even though they boost C yield. And wheat is not economical so very hard to add to crop mix here.
To build OM, you have to retain. Erosion kills OM buy removing it. COC builds organic matter as well but takes more fertilizer, be it manure or commercial and not as drought resistant as crop rotation. None of this may apply to sc Ks hehe.
It is a process, no overnight deals. Will take 10 years or more to get the top few inches of dirt where u want them. But that's where the action is. | |
