Hydrophilic Rock Wool Saline Alkali Soil Improvement

This product is specifically designed for ecological restoration of saline-alkali soils. Made from hydrophilic rock wool, it can be processed into rolls, boards, granules, and other forms to meet the improvement needs of different saline-alkali soil types.

The product utilizes a three-part mechanism—capillary break, salt ion adsorption, and directional moisture control—to physically cut off the upward migration pathway of soil salts while promoting salt leaching by irrigation or rainwater. Compared with traditional chemical amendments, this product introduces no chemicals and poses no risk of secondary pollution. One installation maintains improvement effects for 8-10 years.

• Greening and farmland improvement of coastal saline-alkali lands (tidal flats, reclamation areas)
• Salinized farmlands in inland arid regions (cotton, sunflower, sugar beet, etc.)
• Ecological restoration of industrial salt-contaminated sites (chemical plants, salt production wastelands)
• Roadside green belts and park green space construction in saline-alkali areas
• Soil improvement for protected agriculture (greenhouse soil) in saline-alkali regions

• Physical salt barrier, no chemical pollution: The purely physical mechanism blocks capillary water rise without adding any chemicals, zero impact on soil microbes and groundwater, meeting green ecological restoration standards.
• Capillary blockage, effective salt separation: Installed 30-50cm below the surface, it forms an invisible salt barrier layer, reducing surface soil salinity and lowering root-zone salinity to safe levels.
• High water retention and directional salt leaching: Mass water absorption ≥850%. During irrigation or rainfall, water flows laterally along the product surface to drainage ditches, carrying away accumulated surface salts, achieving "salt follows water".
• Improves soil permeability: Granule or roll forms increase soil porosity, alleviate compaction, and promote root penetration and microbial activity.
• Long-lasting, single installation: Inorganic material resists aging and freeze-thaw cycles, remaining effective for 8-10 years without annual reapplication. Life-cycle cost is far lower than chemical amendments or soil replacement.
