ロンタイ Company Profile

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!

In recent years, following the implementation of slope greening work, we have received numerous inquiries regarding countermeasures due to the increase in damage caused by deer, such as feeding and trampling. A common concern among these inquiries is, "I don't know which method to choose!" With various countermeasure methods available, many people may find that the criteria for selecting them are not well established. In response, Rontai has created a "Design and Evaluation Manual" that aids in method selection based on our testing and performance data, as well as deer distribution maps. Additionally, we have included criteria and points for evaluating results after construction. We also offer free on-site surveys, so if you are struggling with wildlife damage countermeasures, please feel free to consult with us!
