West Central Illinois | Again, you are confusing what the percentages mean. They chose a rate where 75% of the samples contained the same or less P and K. That rate was about 86% of the old rec. I do agree they did not use the average (about 50% level). Looking at the graph, that isn’t a major difference in rate. But it does look like a safe bet to include rates that don’t deplete our soils.
For those of us who are shooting for top yields, the difference in P and K cost is a very small percent of our costs. | |
