AMMONIUM SULFATE for BLUEBERRIES

[dimitri_7a]

This is an old thread but I was hoping you could clarify how much Ammonium Sulfate you use. In a search for it I found you previously said:

@blueberrythrill

I use about 5 pounds of Ammonium Sulfate per 1000 square feet (3X330 foot row). If growth is sluggish, the plants get 2 applications. 100 plants to a row, so each plant gets about 1/10 pound

But in this newer post you say you use 3/4 oz per plant three times per year?

I am planning on using small apps of Ammonium Sulfate + Elemental Sulfate spread over 3-4 times per year to reduce my soil pH from 6.3
