south central MN | For those posting about their experiences with pivot bio or any other biological do this math and post your results please.
Nitrogen use efficiency ratio. Take total Nitrogen applied divided by bushel per acre. Ez. 175#N/230 bushel yield. 175/230=.76 NUE
If your NUE is higher .76 I can assume seeing any gain of a biological would be close to zero. As NUE gets closer to .5 then you would start seeing a result of a biological.
If you are using 100% pre plant or at planting Nitrogen application your chance of seeing a return to a biological would be lower then someone doing a split application.
If you are using anhydrous as a side dress it would be safe to assume that you will not see any result of a biological. | |
