| Corn soybean rotation and our average 10 year aph is around 185 and 55 across all our acres. I looked at the most recent farm we did and there were areas where we applied almost 700 additional pounds of MAP in a 2 year period, but only gain 5 to 8 ppm in the soil. Luckily when we were doing this MAP wasn't $850 a ton. 2017 and 2018 were drought years here and we probably only raised 30 to 40 bu beans those 2 years that we did the builds in.
