Rontai offers vegetation sheets and turf made from the natural resource "straw." Natural straw decomposes and returns to the soil, creating an organic layer that serves as an effective growth medium for plants, making it suitable as a greening cover material. We have a proven track record across various regions in Japan. 【Benefits of Using Straw】 ■ Erosion Prevention → Reduction of runoff water due to straw's water absorption, slowing down flow velocity → Moisture gradually seeps into the soil ■ Insulation and Water Retention → Suppression of surface soil drying, blocking direct sunlight → Straw supplies moisture to the soil, enhancing water retention ■ Minimal Environmental Damage → After plant establishment, straw decomposes into nutrients ■ Insulating Effect → Protects seeds from low temperatures in winter, maintaining germination rates during overwintering *For more details, please refer to the catalog or feel free to contact us.

Rontai offers vegetation sheets and turf made from the natural resource "straw." Natural straw decomposes and returns to the soil, creating an organic layer that serves as an effective growth medium for plants, making it the best material for greening cover. 【Characteristics of Straw】 ■ Erosion Prevention By protecting slopes with straw, it prevents rainwater from directly entering the ground. ◎ Mitigation of raindrop impact ◎ Reduction of surface water flow speed ◎ Decrease in surface water due to straw's water absorption ■ Insulation and Water Retention It blocks direct sunlight and regulates moisture in the ground. ◎ Suppression of surface soil drying ◎ Blocking of direct sunlight ■ Heat Retention It protects seeds from low temperatures in winter. ◎ Protection of seeds from low winter temperatures ◎ Maintenance of germination rates during winter ■ Environmental Conservation Straw contributes to the conservation of the surrounding environment. ◎ After plant establishment, straw decomposes into nutrients ◎ Does not affect the original surrounding environment or ecosystem ◎ Captures airborne seeds Straw maximizes the use of natural forces to promote seed germination and plant growth. *For more details, please refer to the catalog or feel free to contact us.

When designing greening for embankments, Are you worried about whether plants will grow? Do you want to prevent erosion caused by rainfall? Do you want to choose a method that is inexpensive, safe, and environmentally friendly? If you have such concerns, "Ronkett Keeper" can solve them! Ronkett Keeper is a turf product for embankments made by combining "straw" and "special non-woven fabric." It not only prevents soil and seed runoff with its high erosion control effectiveness but also creates a favorable environment for plant growth with its insulation and water retention properties. It is particularly effective for weak soil types against rainfall, contributing to "early greening" and "erosion prevention"! Additionally, the "tension" of the non-woven fabric makes it easy to cut, improving workability compared to our conventional products. *We are currently offering materials that include necessary cross-sectional drawings, floor plans, and work estimates for design! Please feel free to contact us.

The "Ronkettoga" handled by Rontai is a turf for embankments that is environmentally friendly, as all the materials used are biodegradable and decompose naturally.

Would you like to suppress weeds with centipede grass and reduce maintenance costs? ◇ Centipede Grass By incorporating centipede grass, which is expected to have weed suppression effects through its creeping stems and allelopathic properties, it becomes possible to manage it extensively after establishment. While management is necessary until turf formation, straw will help prevent erosion. * Centipede grass is a low-growing variety with a height of 10 to 20 cm. The straw-covered turf "Ronquet Straw" uses natural straw as a covering material, creating an environment suitable for plant growth through the insulation, moisture retention, and erosion prevention effects of straw, effectively protecting embankments. It balances reasonable pricing with high functionality and has numerous implementation records in road construction, land development, and field maintenance projects. Additionally, it contributes to environmental conservation as it is decomposed by soil microorganisms.

"Ronkett Tunagreen" is a product that secures straw to a vegetation sheet with machine stitching and covers it with a polyethylene net for reinforcement. Due to the fine stitching intervals, it is less likely for the straw to scatter even in strong winds, and the amount of straw that falls off from the ends when cut is also reduced. It contributes to improving work and management efficiency in the use of straw-based vegetation sheets, which have various features such as erosion prevention, thermal insulation, and water retention. 【Features】 ■ Market-priced product ■ Straw-attached vegetation sheet (without fertilizer bag) ■ Prevents straw scattering due to strong winds ■ Achieves high adhesion through net coverage ■ Reduces loss as straw is less likely to fall off during installation and cutting *For more details, please refer to the materials available for download in PDF format. Feel free to contact us as well.

The soil stabilization vegetation sheet "Ronkette Tsunagreen" uses straw as a covering material, enabling stable vegetation through the excellent water retention and insulation effects of straw, as well as its erosion prevention capabilities.
