West Kentucky | "It's the concentration of P in the soil (ppm) that is most tightly correlated to crop response"
Can you expand on what you are talking about? My understanding is that lbs per acre and PPM are a reflection of the same number just read differently and will end up with the same concentration. I 100% agree with the fields of ours with the highest P readings tend to be our highest yielding fields and lowest P readings tend to be our lowest yielding fields. It tends to be difficult to build though. | |
