| Very good explanation GTD. It concurs with my actual experiences that you can band and reduce rates but someday you will find yields dropping and then its a slow catch up game to get soil test levels back where you were. Can you explain why in manure applications the standard % is close to 70% of what you applied is available the first year??
Thinking back when a snake oil fertilizer salesman told me his product was more available and I could use half as much fertilizer. They get you to do a side by side and you know what happens the first couple years???Yields are the same. They live off your residual soil fertility. Problem is the stuff is WAY to expensive per unit applied. If one was to keep doing the test and not apply any added fertility to HIS side, the yields would drop in my opinion. But they know thats hard to accomplish because of spreader overlap, not marking the same spot ect...Most farmers would not go that far. | |
