Northwest Ohio | So the two facts that can be proven from these studies is that:
1. Spreading Phosphorus adds to phosphorus in runoff
2. The more rain fall, the more runoff.
At the winter soil and water district meeting this year was the NRCS head of hydrolysis. He basically said the same thing. The more rain or more water velocity, the more nutrient runoff. How do we decrease water velocity or rainfall event intensity?
One thing that bothers me about the studies is the image below. I have seen a lot larger cracks in dry convention tilled fields then what they show here. So is this more of tillage practices or that fact that we are still broadcasting phosphorus?
