Little River, TX | A good bit depends on why the higher pH.
If you have a calcareous soil that is one thing, If that is the case ammonium sulfate will not be a long term cure for pH.
Not even Anhydrous ammonia will lower the pH for long,
Not only that but with your pH your soil test for phsophate should be the Olsen chemestry not Bray.
Here in our clay your potassium levels would be low to deficient. For a 30 CEC the K should be in the 300 ppm on the low side and l80 ppm on thew high side. Hint next season pull tissue samples to help calibrate your soil test results. Even a 20 CEC would do better with well over 200 ppm K, better in the 300 ppm K range
I suggest you have a Free Lime analysis also for your next soil analysis. Maybe also ask for a measured CEC to boot. Warning the free lime is as or more than the cost of a soil analysis, and the measured CEC is 4 X the cost. Good thing is your actual CEC will not change unless you bring in a lot of different soil.
Here is a 40 to >50 CEC, 8500 ppm Ca and 4% to 6% free lime. The soils are high shrink clay loam.
Is midwest Labs is your Lab> They like to report about half the calcium level which computes to a 30 CEC.
