Help soil hold moisture longer, from farms and orchards to home gardens.

## Product terminology

- Agricultural hydrogel is also known as water retaining granules or a soil water retainer. Our agricultural range includes potassium polyacrylate for root-zone moisture management.
- Product keywords: Agricultural Hydrogel; water retaining granules; soil water retainer; potassium polyacrylate

## Product information

- Water retaining granules are functional super absorbent polymers that form a miniature reservoir around plant roots. They help maintain a moist root environment and improve soil water and fertilizer retention.
- They improve water and fertilizer utilization and support soil structure and aeration. Suitability and dosage depend on crop, soil and local conditions; ask our team for application guidance.

## Product specifications

- Dry form: White granules
- Particle size: 30–100 mesh
- After hydration: Hydrated gel
- Planting guide: Household planting · Item 110
- The household guide applies to Item 110. It allows increased rates in dry, drought or extreme conditions; confirm any adjustment for the selected grade, soil and local conditions with our team.

## Granule specification

- The supplied product image lists white granules, 30–100 mesh. Confirm the grade for the intended application.

## Application examples

- Tree transplanting and root-zone placement; crop seedlings in furrows; lawn turf; forest planting; landscaping.

## Household planting guide — Item 110

- Wet mix: mix 1 teaspoon with 500 mL of water, wait 1 hour, then mix the expanded granules with 5 L of potting mix.
- Dry mix: mix 1 teaspoon with every 5 L of potting mix, pot up the plant, then water thoroughly.
- Established plants: make vertical holes toward the root zone, add granules, water in, then fill the holes.
- Laying turf: evenly spread 10 g/m² before laying turf, then water.
- Sowing seeds: mix 10 g/m² into the top 50 mm of topsoil, sow the seeds, then water.
- These quantities are from the supplied Item 110 household-planting guide. Suitability and dosage depend on the selected grade, crop, soil and local conditions. Contact High Smart for other grades or adjusted application rates.

## From dry granules to hydrated gel.

- Fine white granules absorb water and form translucent, irregular gel particles.
- Before hydration: Fine white dry granules. After hydration: Translucent hydrated gel particles.
- Dry granules
- Contact with water
- Water absorption and gel formation
- This illustration shows how the material changes, not its actual expansion ratio or absorption speed. Confirm water quantity and soaking time for your chosen grade.
- Before-and-after illustrations; sizes are not shown to scale.

## How hydrogel changes moisture retention.

- Explore how a water-retaining polymer holds moisture around the roots.
- Without water-retaining agent: Water moves through soil pores without an added polymer reservoir.
- With water-retaining agent: Hydrated polymer holds water near the roots and releases it as the surrounding soil dries.
- Illustration of root-zone water retention; actual performance depends on the grade, soil and environment.

## Item 110 · Wet-mix example

- Dry granule quantity: 1 tsp
- Water added: 500 mL
- Soaking time: 1 h
- Potting mix to add after soaking: 5 L
- Wet-mix example for this item. Confirm quantities and soaking time for your chosen grade. The animation is sped up and does not represent a measured absorption rate.
