Saline-alkali soil is a double threat: it poisons plants and suffocates the ground. High salt levels act like a "thirst trap," pulling water away from roots even when the soil looks wet, while high pH levels block the plant from "eating" nutrients.
SOCO soil hydrogel is designed to fix saline‑alkali soils where high salts create osmotic stress, poor structure blocks roots, and water either runs off or waterlogs. It lowers salinity, rebuilds aggregation, and boosts water-holding capacity while maintaining drainage—balancing water and air so roots can access steady moisture and nutrients.
Cotton, China
With SOCO® Soil Hydrogel Can Increase Yield by 28.1%
1. The cotton with SOCO® Soil Hydrogel had stronger growth in the middle and late stages, with green leaves and luxuriant branches, and most of the cotton dolls grew better.
2. The final yield of cotton was increased by 28.1%.
Traditional SAPs are designed for low-salt environments. High salt concentrations suppress their swelling ability, significantly reducing water absorption and retention performance.
Salt-tolerant SAPs maintain high swelling capacity even under saline conditions. They form stable root-zone micro-reservoirs that provide sustained, slow-release moisture for up to 28 days.
By forming moisture-retaining micro-reservoirs near roots, they reduce fertilizer leaching and increase nutrient residence time, especially in sandy, low-fertility soils.
Yes. Field results show effective performance in saline-alkali soils ranging from pH 7.1 to 8.5, and broadly applicable within pH 7–9 environments.
They are typically dry-applied (banded or incorporated) at recommended rates (e.g., ~75 kg/ha), fitting standard agricultural field operations without requiring special equipment.
Yes. They maintain swelling and moisture-release performance across repeated wet–dry cycles, extending hydrogel benefits throughout the growing season.
