Soil sample analyze

Question

I pulled a few samples they all show a high ph on tiled ground. Wondering what I need to do to bring ph down and help balance out nutrients.

Answer

In my humble opinion... i would focus on the following

First and foremost, focus on bringing up your Phosphorus levels. I shoot for 100 ppm of P.

Secondly, your high pH is likely from your high base saturation of Calcium and Magnesium with extremely low K% base saturation. I have not had pH's in the 8's before, but I would be adding a large amount of Elemental Sulfur and Potash at the same time to replace some of the Ca and Mg when the Elemental Sulfur blows it out. It will take some time, but the good news is that you have drainage tile to wash it away.

Good luck -- I am very curios what you ended up doing.

Answer

Advise does have some trials on trying to lower PH in our heavy red river valley soils. They also have tried raising K levels on base saturation test. If you look on there website you can find it. I would focus on raising P and sulfur levels.  Also when doing a soil sample have a 6-24" test too to see salts and PH.

I have soils with salts and have patterned tiled my ground over last 10 yrs my PH is still up there 7.8 to 8.1  hopefully it will come down more but might take awhile. Did mostly 50' spacing and some 40'

Answer

I’m assuming this is on heavy clay? 46 cec is crazy to me. I’ve always heard elemental sulfur to bring down pH. But it will be multiple years before you start to see changes. Switch to high ammonium fertilizers (ammonium sulfate, anhydrous) and no more carbonates. Bring pH within range will help with availability. Exchangeable K is high but with a 46 cec your base saturation of K is very low. Phosphorus is also low, likely all related to alkaline soils. Good luck! Most of the work is done with the tile though, big help!
