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.
Can I acidify soil with vinegar?
