LVHAN Agro-Forestry Water-Retaining Polymer
Absorbs 300–500× its weight · active 3–5 years in soil
A super-absorbent polymer that takes up 300–500 times its own weight in water and releases it slowly to roots, again and again, like a small reservoir in the soil. Used in farming, forestry, water conservancy and sand-land projects for drought protection, higher yields, soil improvement, sand fixation and soil and water conservation. Non-toxic and harmless.
Key features
- Strong water and fertilizer retention
- Improves soil structure, aeration and drainage; helps prevent crusting and salinization
- Stable, with a working life of 3–5 years in soil
- Resistant to sunlight
- Tolerates saline-alkali conditions and can be used together with chemical fertilizer
- Rich in potassium, iron and other nutrients
Rates and methods
How to apply it
| Field crops | About 3 kg per mu (45 kg/ha, about 40 lb/acre), mixed evenly with base fertilizer or spread and ploughed in |
|---|---|
| Seed coating | Make a gel at 1:100 to 1:200 polymer to water, stir seed in, rest 4–6 hours, then dry and sow |
| Root dipping | Same gel ratio; soak roots, wrap and plant. 1 kg of dry polymer treats about 2,000 seedlings |
| Planting-hole application | About 25 g per 2–3-year conifer seedling, 40 g per 1–2-year broadleaf seedling, 60 g per 2-year orchard seedling |
| Lawns and beds | Sandy soil 100–150 g/m², loam 50–100 g/m², clay 30–70 g/m² |
Measured results
