Overapplied Sulfur for blueberries
I'm hoping for some advice. I have been amending a patch of soil over the past year, in anticipation of planting 28 bare-root blueberry plants, which are set to arrive next week. I just got my final soil test back, and realized that, in the fall, I think I tilled in way too much granular sulfur! I had 50 lbs tilled into a 1000sf area, which comes to something like 2240 lb/acre. I have no idea what I was thinking, but this is quite a bit more than recommended.
The soil test shows that, over the winter, the sulfur brought the pH down from 5.7 to 5.3, so it's already pretty close to ideal. However the test also shows that the sulfur level in the soils is *still* quite high (143ppm), so i'm afraid that quite a bit of acidification will take place once the soil warms up. (I'm in Vermont, so probably not much of it broke down over the winter). My organic matter came in at 6%, which I think will help buffer things, but i'm still worried about the abundance of sulfur still in the soil.
I'm considering adding Dolomitic Lime to counteract sulfur's effect, but have no idea: in theory, would this even work? I need to add a little Mg as well, so thought this might help. Please let me know if anyone has any experience with a sulfur overdose.
