Nanotern: Smart Subsoil Water Reserve
Advanced Water-Retention Technology for Soil, Turf & Agriculture
Developed through advanced polymer and nanotechnology research, Nanotern is a water-retention technology designed to store available moisture, slow water loss and improve water availability around plant roots.
From agriculture and horticulture to professional turf and landscaping, Nanotern helps plants and landscapes make better use of rainfall and irrigation — supporting more efficient, resilient and water-smart growing systems.
What is Nanotern?
Nanotern is a biodegradable Super Absorbent Polymer (SAP) designed to act as an underground water reservoir for plants.
Applied directly into the soil, Nanotern absorbs irrigation water, rainwater, and nutrients, then gradually releases them back into the root zone when plants need them most.
Nanotern is suitable for all major soil types, including sandy, clay, silty, loamy, peaty, and chalky soils.
Key Benefits:
✓ Improves water retention in the root zone
✓ Reduces drought stress
✓ Enhances nutrient-use efficiency
✓ Biodegradable technology
✓ Not a fertilizer – works alongside existing nutrition programmes
How Nanotern Works
How To Use Nanotern
Recommended Application Dosage:
Seedlings: 3–5 g per seedling (½–1 teaspoon) Apply to the root zone at planting by mixing with the soil.
Trees / Saplings
- Young saplings: 50–150 g
- Mature trees: 200–500 g Apply near the canopy drip line using the pit or ring method.
Garden / Open Field: 2–10 kg per decare (depending on plant density) Localized application per plant is recommended.
Application Notes
- In sandy soils, the application rate may be kept close to the upper limit.
- In clay soils, the lower limit is sufficient.
- Surface broadcasting is not recommended.
- Initial irrigation after application is recommended.
- Compatible with drip and sprinkler irrigation systems.
