The main cause of high ph is lack of drainage. Which I am in the process of grid tiling this fall #1 priority. my %Base Saturation of Ca is 89, my Ca ppm is 5211 and yes my test always show I am short on Phosphorus. I did sideress with NH3 one year and that was my best yeild. I have usually been using UAN as my N source.
Drainage or not ? the Calcium is displacing the Hydrogen
I suggest using NH3 as a N. source and apply adequate amounts of K to displace the Calcium
I have applied 400 to 800 Lbs per acre rate depending on the crop and the cash flow of the operation.
AMS as suggested is also Blended with the K on each and every application, and vise verse, K with AMS
watch you Magnesium and Manganese also
