The desert of MN. | Anybody have any trial data testing potash rates before Soybeans? Can't seem to find much searching the web. Some background. We put our first pivot up last year. Next year half of that pivot will be beans. Now that water will not be our limiting factor on our sand looking to push bean yields. Talking with the head agronomist at our coop he says K will be our next limiting factor after looking at the grid samples. This is blow sand with CECs in the 5-6 range, OM 1.1-2.2 and K levels 52-80ppm. Will I see a ROI if i apply 3-400lb 0-0-60 this fall? I plan on leaving a couple check strips to find our for sure. Sure which I had a source of litter or manure around but we don't. | |
