Potassium-Based SAP for Agriculture
High-performance super-absorbent polymer that absorbs 300-500x its weight in water, forming a soil micro-reservoir for water-saving, higher-yield farming. 100% biodegradable, certified to ISO 9001 / 14001. Annual capacity 80,000 tons.
Funder potassium-based SAP is a high-performance functional polymer (potassium-based polyacrylate / polyacrylamide composite) that rapidly absorbs 300-500x its weight during irrigation or rainfall and slowly releases it on demand, creating a micro-reservoir in the soil. A proprietary copolymerization embeds nano-scale attapulgite clay, boosting water retention and salt tolerance while improving soil structure. 100% biodegradable, no microplastic residue.
Each granule swells into clear hydrogel on contact with water, forming interconnected micro-sacs in the root zone that lock rainfall and irrigation near the roots, preventing evaporation and deep percolation loss, and releasing water slowly as soil potential changes. Plant root suction (17-18 kg/cm2) exceeds SAP holding force (13-14 kg/cm2), so water flows one-way with no reverse uptake. Active 3-5 years, then degrades into nutrients and minerals.
Key Performance Parameters
| Water absorption | 300-500x own weight in pure water; 60-100x even in 0.9% saline |
|---|---|
| Effective period | 3-5 years per application (3-6 for some crops) |
| Water-saving | Rainfall use +40%; irrigation water cut by up to 1/3 |
| Fertilizer efficiency | Locks water-soluble fertilizer; use efficiency +30%, chemical fertilizer -30% |
| Weather resistance | UV-stable; wide temperature tolerance |
| Soil conditioning | Adjusts pH 6.0-8.0; supplements K, Fe; suppresses salt stress |
| Safety | Non-toxic, food-grade safe, no microplastic residue |
Six Core Advantages
Water Efficiency
Micro-reservoir supplies water continuously, lowering irrigation frequency and cost, relieving drought stress.
Yield & Income Growth
Stable moisture promotes growth, shortens maturity, improves yield and quality.
Fertilizer Retention & Slow Release
Locks water and nutrients, reducing loss and leaching to raise nutrient-use efficiency.
Soil Improvement
300x+ swell-shrink cycles loosen soil, increase porosity and aeration, stimulate roots.
No Reverse Uptake
Root suction exceeds SAP holding force; water flows one-way, never back into the polymer.
Salt & UV Resistant, Eco-Friendly
Tolerates saline/alkaline soil and UV aging; 100% biodegradable into N, K and attapulgite.
Why Choose Funder SAP
Potassium-Based Nutrition
A potassium-based polymer that releases potassium nutrients as it holds water - more crop- and soil-friendly than ordinary sodium / polyacrylate types.
80,000 t/yr Capacity
A large-scale SAP base in China with 80,000 tons annual capacity, ISO 9001 / 14001 certified, for stable supply and predictable lead times.
National 863 Program Heritage
Originated from China's National 863 High-Tech Program SAP industrialization, backed by a Shenzhen-listed group (002476), with a provincial technical center and postdoctoral research workstation.
100% Biodegradable
After its service life it degrades into nitrogen, potassium nutrients and attapulgite minerals - no microplastic residue, permanently improving soil, aligned with global sustainable agriculture.
Application Methods & Dosage
| Method | Suitable for | Rate / Key points |
|---|---|---|
| Mechanized seeding | Row crops in open fields | Blend 2-5 kg/mu with fertilizer, 10-20 cm furrow |
| Furrow application | Peanut, wheat etc. | 2-5 kg/mu, 10-20 cm furrow |
| Broadcast | Leafy veg, lawns, seedling beds | 6-10 kg/mu, mix into 5-10 cm soil |
| Hill application | Tomato, pepper etc. | SAP:soil 1:5-10, 10-20 cm hill |
| Seed coating | Boosts germination | 0.5%-1.0% hydrogel coat, shade-dry, sow |
| Root-dipping transplant | Seedlings, fruit trees | Gel SAP:water 1:100-150, dip 3-5 s, 95%+ survival |
Typical Crop Applications
- Field crops (wheat, corn, peanut): furrow or seed-mix, 10-15 cm deep, 3-5 kg/mu
- Economic forests & fruit trees: ring/trench in root zone 30-50 cm deep, 20-80 g/plant
- Avocado: ring/strip trench 5-10 cm deeper, fertilizer -30-50%
- Date palm: desert sandy soil, 150-200 g/tree, irrigation interval +15-30 days
- Nurseries & vegetables: root-dip gel (1:100); container mix 50-400 g crystals
- Potato (benchmark): 60-80% soil moisture, uniform tubers, higher total yield
- Greenhouse flowers, golf turf, urban greening, afforestation & ecological restoration
Proven Crop Applications
Wheat & Field Crops
Furrow or seed-mix at 3-5 kg/mu for precise moisture and sharply lower irrigation dependence.
Potato - Benchmark Case
Maintains 60-80% soil moisture; markedly improves tuber size uniformity and total yield.
Date Palm & Desert Farming
150-200 g/tree in sandy soil; irrigation interval extended 15-30 days, drought-proofing seedlings.
Orchard & Nursery Transplant
Root-dip gel (SAP:water 1:100-150) for 3-5 s; transplant survival 95%+.
Sustainability & Fit
Remains highly active in soil for 3-5 years; after service life it naturally biodegrades into beneficial nitrogen and potassium nutrients and attapulgite minerals, leaving no harmful residue and permanently improving soil structure.
Target Markets
Middle East / North Africa (Saudi Arabia, UAE urban greening & food security), Australia / South Africa (drought-prone belts), Europe & the Americas (organic farming, government agencies), plus Ukraine, Brazil, Argentina, Egypt, Kazakhstan and Canada.
