Minnesota/Kentucky fertility based on ENERGY | The ratio's which I was taught would be anything above a 7 to 1 ratio this applies to any soil test on the base saturation.
the CEC question is good, our CEC's run anywhere from 8 to 22 and we run the same program across everything, the only thing that might change would be the foliar's applied if a farm needs to be tweaked?
the years of the drought commit is interesting, the Osage, IA farm using the same program and the same nitrogen program had better yields than 2011 I believe 206 to 210 bushels per acre, so in the case of this grower did mother nature cause the same problems? or did he weather proof his crop? I'm trying to sort through some of the data.
I believe a soil test is only a measurement of the soil at that time, its a snap shot of your farm that minute, beyond this its about "see what you look at, look at what you see" my mentor god rest his soul Dr. Dan Skow. |
