| Like many others already posted, I believe less Residue breakdown makes field wetter in spring. Early planted beans this is more important than ever. We are hour north of St. Louis and most years there is almost nothing left of residue behind Roto Disc ran early September come spring. If you have low k tests and only spread k in front of corn then it could play into it, but if you soil test are good and you spread every year I believe it’s all seed bed related. We will never go without chopping head now that we got one. The cost of head and extra fuel is worth it for us. We no till beans, minimum till in bean stubble, and full till corn on corn. We can run an old dmi 530b(4K value) behind that corn head and after field cultivator runs through it it looks like we used a new 875 or dominator in fall. It can replace vrt tool.
I also think that’s why every late fall seems to be followed by an avg to below avg yield. We tend to start planting same time every year regardless of conditions. | |
