WC Mn/Dakotas | That comes from knowledge of soil chemistry from my fertility specialist and those he works with. It depends on cec, ph, o.m. and moisture. Here we have predominantly 25-35 cec, 7.4-8ph, 3-5% o.m. For all practical plant uptake purposes, p & k wont hardly move from where it is placed, here. If ww dont get pk incorporated in fall for corn, we wait till after corn harvest to apply. Have donr that on close to 20k acres in last few years and still made record yields. We will try to maximize infurrow popup, if possible. | |
