Specialized for strongly acidic soils, new natural growth-type greening method "Soil Bacteria Strongly Acidic Countermeasure Method"
It is a new natural growth-type greening method that specializes the conventional soil bacteria method for more acidic soils.
**Soil Bacteria Strong Acidity Countermeasure Method** The "Soil Bacteria Strong Acidity Countermeasure Method" is an effective vegetation technique for slopes containing factors that inhibit vegetation, such as strongly acidic soil (pH ≤ 3). By combining a shielding layer created through soil-cement spraying with a vegetation foundation layer established using soil bacteria methods, it provides stable greening in areas where conventional vegetation has been difficult. **Soil Bacteria Strong Acidity Countermeasure Method System** In the "Soil Bacteria Strong Acidity Countermeasure Method," the vegetation-inhibiting factors present in the ground are shielded by soil-cement spraying, and a vegetation foundation layer is created on its surface. The hard shielding layer formed by soil-cement spraying restricts not only the growth of vegetation roots but also the supply of moisture and nutrients, meaning that the vegetation foundation layer constructed above the shielding layer will largely depend on many of the conditions for plant growth. Taking this into account, the vegetation foundation layer employs a soil bacteria method that possesses self-fertilizing capabilities, eliminating the need for additional fertilization.

basic information
**Background and Development of Soil Bacteria Strong Acidic Countermeasure Methods** In Japan, where precipitation is high, soils are prone to acidification due to the leaching of basic substances, resulting in a prevalence of acidic or weakly acidic soils. Among these, podzols, volcanic and marine acidic sulfate soils, and "bota-yama" (mound-like formations) often exhibit strong acidity (pH below 3.0), making it difficult for green plants to thrive. In such strongly acidic soils, the absorption of essential nutrients is significantly restricted due to factors such as inhibited root elongation, damage to cell membranes, and phosphorus deficiency. **Vegetation Damage Caused by Strongly Acidic Soils** When vegetation work is carried out on slopes of strongly acidic soils (pH below 3), poor vegetation growth occurs over time, and under certain conditions, plants may die shortly after germination. This is attributed to the harmful effects of hydrogen ions, excessive aluminum and manganese toxicity, deficiencies in phosphorus, bases, and other trace elements, as well as poor nitrification and nitrogen fixation processes.
