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 specialized for more acidic soils, based on the conventional soil bacteria method.
**Soil Bacteria Strong Acidity Countermeasure Method** The "Soil Bacteria Strong Acidity Countermeasure Method" is an effective vegetation technique for slopes that contain factors inhibiting 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 considered difficult. **Soil Bacteria Strong Acidity Countermeasure Method System** In the "Soil Bacteria Strong Acidity Countermeasure Method," the factors inhibiting vegetation present in the ground are shielded by soil cement spraying, and a vegetation foundation layer is created on the surface. The hard shielding layer made from soil cement spraying restricts not only the growth of plant roots but also the supply of moisture and nutrients, meaning that the vegetation foundation layer constructed on top of the shielding layer will depend heavily on many 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** The soils in Japan, which experience high precipitation, are prone to acidification due to the leaching of basic substances, resulting in a predominance of acidic or weakly acidic soils. Among these, podzols and volcanic or marine acidic sulfate soils, as well as areas like "bota-yama," exhibit such strong acidity (pH below 3.0) that the growth of greening plants becomes difficult. In such strongly acidic soils, the absorption of essential nutrients is significantly restricted due to factors such as inhibition of root elongation, damage to cell membranes, and phosphorus deficiency. **Vegetation Damage Caused by Strongly Acidic Soils** When vegetation works are conducted on slopes of strongly acidic soils (pH below 3), poor vegetation growth occurs over time, and under certain conditions, phenomena such as death shortly after germination can be observed. This is attributed to the harmful effects of hydrogen ions themselves, excessive damage from aluminum and manganese, deficiencies in phosphorus, bases, and other trace elements, as well as poor nitrification and nitrogen fixation processes.
