★★Notice★★★ We are releasing an effective greening method specialized for strongly acidic soils: "#Soil Bacteria Strongly Acidic Countermeasure Method"★★★
★★─────────────────────── Announcement March 30 Edition 【Notice】 We have released an effective greening method specifically designed for strongly acidic soils, called the "#Soil Microorganism Strongly Acidic Soil Countermeasure Method." ───────────────────────────────★★ The soil microorganism method has accumulated a track record as an effective greening method for soil-less, poor-quality soils, rocky slopes, as well as strongly acidic and strongly alkaline soils. We have now added a new method, "Soil Microorganism Strongly Acidic Soil Countermeasure Method," which is more specialized for strongly acidic soils, to our lineup. The "Soil Microorganism Strongly Acidic Soil Countermeasure Method" creates a shielding layer through soil-cement spraying to mitigate the adverse effects of strongly acidic soils, and then constructs a growth substrate layer that incorporates microbial materials (effective soil microorganisms) on top of it. If you have a site troubled by strongly acidic soils, please consult our staff.
