what kind of materials could i use to raise the acidity in my soil?? this is something im covering at college at the moment so you'd be helping a bunch guys :-D i know a few, but i dont know them all. thanks!!
Ammonium sulfate, and sulphur coated urea will acidify soils. Elemental sulfur and iron sulfate will also acidify, but in established beds you have to apply only a little, or it will burn the plants. If the bed isn't yet planted, adding the acidifying agents a month or more ahead of planting allows them to do their work.
thats great thanks. didn't know those ones. are these things you can buy from your regular garden centre??
I don't know what is available in the UK. We can get ammonium or iron sulfate at our farm/ranch supply store.
When I tried to acidify new england soil with organic components, ie peat coffee grounds etc; for blueberry, none of them were adaquate to my need. Ammonium sulphate or sulphur was the only thing that did the heavy lifting I needed.
