Which fertilizer increases the acidity of soil?
Nitrogen Fertilizers Nitrogen sources — fertilizers, manures, legumes — contain or form ammonium. This increases soil acidity unless the plant directly absorbs the ammonium ions. The greater the nitrogen fertilization rate, the greater the soil acidification.
How do you acidify soil quickly?

Can you use vinegar to acidify soil?

The most commonly used liming material is agricultural limestone, the most economical and relatively easy to manage source. The limestone is not very water-soluble, making it easy to handle.
Are Epsom salts basic or acidic?
