Support Plant Growth, Yield and Resilience

AgriSea Foliar Nutrition delivers a balanced mix of nutrients and bioactive compounds directly to leaves, providing an instant boost that is readily absorbed by the vine, plant or tree. Foliar spraying with our seaweed has proven to be up to 95% efficient. Under ideal conditions, nutrients can be translocated into the plant within one hour, ensuring rapid uptake and utilisation.

Our unique cold-extraction method maintains the integrity and structure of natural amino acids, plant hormones (auxins, gibberellins and cytokinins) and native brown seaweed bioactives (polysaccharides, phlorotannins, mannitols and betaines). These compounds are severely compromised when chemical or heat extraction methods are used. Together, they promote cell division and expansion resulting in larger fruit, stronger roots, and faster nutrient and water uptake. Our bioactives also help condition plant performance by supporting stress tolerance, antioxidant protection and water/osmotic balance, keeping crops greener, more vigorous and more resilient when facing New Zealand's harsh climate. Treated crops show a significant lift in fibre, protein and overall nutritional value, with higher dry matter yields and increased brix levels to improve the taste, storage life and market quality of your fruit.

Safe, non-toxic, and free from chemical additives, thickeners, preservatives or residues, it's a practical tool for growers seeking quality, resilience and sustainable production.

Frequently Asked Questions

What is AgriSea Foliar Nutrition?

It's a seaweed-based foliar spray designed to deliver nutrients and bioactives directly to plant leaves for improved growth, fruiting and stress resilience.

Why apply nutrients to the leaf instead of the soil?

Applying it to the leaf helps nutrients get directly into the plant instead of being held back by poor soils or risk being washed away, allowing faster uptake and a more consistent response. This product can be used alone or in conjunction with AgriSea Soil Nutrition for optimal results.

Can I mix Foliar Nutrition with other products?

Yes, except with fungicides. Always check compatibility before large-scale tank-mixing.

Is it safe for humans, animals, and the environment?

Yes. This product is non-toxic, chemical-free, and has no withholding period.
