| We've started plowing a few acres that we spread manure on after wheat harvest. I plowed an 80 a couple years ago that was wheat stubble with manure. Planted corn on it the following year and then soybeans last year. Had it soil sampled last fall after bean harvest. Ive never seen fertility levels so high across the board. We're usually high in soil potassium and some micros anyway, but everything was in the high column. I couldn't believe it at first. So i guess there is truth to releasing extra nutrients if it hasn't been plowed in a long time. I also had bad waterhemp problems stemming from the wet years in 2019-20. The plowing definitely did a good job burying much of the seed bank, so that has made weed control so much easier and helped the field has stayed cleaner in general. And this 80 also has a few areas of low, gumbo soil that are very tough to dry out, so plowing helped loosen those areas out and are much easier to farm through now. I understand some areas shouldn't be plowed cause of soil type. But i firmly believe now that some soil types should be plowed every so often to help reset it. Especially after having tough wet years. | |
