NW Iowa | Dap, potash, AMS, zinc sulfate, those are what I have run down lines.
Cooling effect. Well all I can say is that I have not seen curled leaves on corn. I know it's not the same as pivot dumping water on plant to cool it.
What might be happening is the cool water being pumped into soil is cooling soil and helping. It's just a guess cause I have not taken temps on soil yet. But pumping 52 degree water into soil has to have some effect. I think soil temps in 80 s is bad. | |
