S Illinois | My question would be how is everything tied together. Are your high pH areas the same areas as the low P and K areas. Without seeing how the maps overlay against each other I would be a little carefull about attributing yield to just one thing. Many time there is more than one interaction going on. To have an honest comparison on pH all other nutrient levels should be equal. There is a chance your low pH areas could do even better if the pH is brought up. | |
