[NEW] A vegetation mat designed for strongly acidic soils! It achieves greening with a blend of permeable soil amendments and seeds that are resistant to acidity.
- Slope protection material
We have launched the new strong acid and alkaline soil compatible vegetation mat "Ronkett Healer"!
The pH of the soil has a significant impact on plant growth. In soils that exhibit strong acidity or alkalinity, the absorption of nutrients by plants is hindered, preventing root growth and inhibiting development. In Japan, due to geographical and meteorological factors, soils tend to be acidic, and there are also soils that show strong acidity. Additionally, as a result of soil improvement for land development and slope stabilization measures, there are many cases where alkaline slopes are created. In response to this, Rontai has launched a new product, "Ronkette Healer," that can accommodate both acidic and alkaline soils! The "Ronkette Healer Ac," a vegetation mat for strongly acidic soils, is designed to handle pH levels of around 3 to 4, and we offer three grades that focus on neutralizers and seed blends. The "Ronkette Healer Ak," a vegetation mat for alkaline soils, is designed to handle pH levels of around 10, and we offer four grades that can be selected based on soil hardness and site conditions. We also support on-site surveys and soil acidity measurements, so if you are struggling with greening in strongly acidic or alkaline soils, please feel free to consult us!
[NEW] This is a vegetation mat suitable for alkaline soils! You can choose from four grades depending on soil hardness and site conditions.
