What This Product Does

AgriSea Soil+ is a solid, slow-release soil conditioner that combines our Soil Nutrition liquid concentrate with natural zeolite to support healthier, more productive soils. Zeolite is a naturally occurring aluminosilicate formed through volcanic activity in the Rotorua/Taupō region. Its unique structure holds nutrients and moisture in the root zone, releasing them in response to plant demand rather than leaching away. As plants take up what they need, zeolite slowly recharges and reabsorbs soil nutrients, creating a natural cycle that maximises fertiliser and soil conditioner efficiency.

AgriSea Soil+ supports stronger root systems, increases root length and mass, and promotes higher germination rates for cropping and re-grassing. It encourages more natural nitrogen fixation (reducing the need for synthetic fertilisers), and helps reduce pulling. It also improves soil structure for better aeration, drainage and traffic tolerance, builds a deeper humus layer, and unlocks bound minerals and nutrients to make them bioavailable to plants. The result is improved pasture quality, increased crop yield, greater drought resilience and faster recovery after stress, all from a product that remains active in your soil for years to come without breaking down.

Nurture the long-term health of your soil to ensure your land is productive, resilient and profitable.

How to Use

Prepare

Use 20kg of AgriSea Soil+ per hectare. Load into equipment suitable for your farm or growing operation. Mix with existing nutrients or use as a stand-alone application.

Timing

Purpose	Application Timing
Autumn Rebound	Early autumn
Winter Preparation	Late autumn / early winter
Spring Jump-Start	Early spring
Summer Resilience	Late spring

Frequently Asked Questions

AgriSea Soil+ does not break down over time. The zeolite remains in the soil, continually improving nutrient and water retention while recharging as nutrients are applied. It is also a solid product rather than a liquid seaweed biostimulant. Both of these products are designed to complement each other and ideally should be used together.

Unlike other soil products, AgriSea Soil+ does not break down. Once the Soil Nutrition is extracted, the zeolite remains in the soil to help improve nutrient and water retention permanently. Like most biostimulants, the best results come from continued biome support through frequent applications.

Zeolite has a high cation exchange capacity (CEC), meaning it holds nutrients in the root zone and releases them in response to plant demand, reducing losses and improving uptake. Plant-driven nutrient release is desirable as it sets up a natural cycle for nutrient uptake. It has also been proven to extend the availability of soluble phosphorous and sulphur products.

Yes. AgriSea Soil+ is designed to complement existing nutrient management programmes. Check compatibility with other products with your local AgriSea Area Field Consultant.

No. AgriSea Soil+ is safe, non-toxic and has no withholding period.
