WebDec 2, 2024 · In soils with a pH of between 3 and 5, most plant nutrients will become more soluble and be more easily washed away. And below a pH of 4.7, bacteria cannot rot organic matter and fewer nutrients become available for plants. Those are the main two reasons to make soil more acidic. But there are a few other random reasons. Web1 day ago · Since organic matter ties up aluminum, plant growth is possible at lower pH levels than in mineral soils. For mineral-organic (M-O) soils, the target pH is 5.5; and for organic soils, 5.0. The amount of humic matter (HM) and the soil density (weight/volume ratio, W/V) are the criteria used for these three soil class determinations by NCDA&CS.
