NZBioActive is made exclusively with 100% wild harvested fresh seaweed, undaria pinnatifida, using a cool temperature extraction process to retain higher levels of plant growth regulators and nutrients. Fresh is Best! With a 70% minimum seaweed content, NZBioActive extract has one of the highest amounts of dry matter available.

The perfect accompaniment for both conventional and organic operations to increase crop quality and production, NZBioActive is a comprehensive broad spectrum fertiliser providing over 70 key nutrients as well as a range of naturally occurring carbon compounds (amino acids, plant hormones, alginates, sugars, etc.) that work with soil and plant biology to facilitate nutrient uptake, enhance immune response and help reduce leaching losses.

NZBioActive maximises the health of your entire crop - roots, stems, leaves and fruit, and
stimulates plant enzymatic and hormonal activity, improving pest and disease resistance. 

The combined biochemical activities, nutrients and up-regulation of gene expression bring increased photosynthesis, nutrient uptake and anti-oxidation activity. NZBioActive boosts yields by stimulating soil microbial activity and plants’ natural defences and immunity especially during early growth and periods of stress such as drought, heat, frost, disease and pest pressure. 

Suitable for soil, foliar and fertigation applications and is best used in conjunction with spray programmes to reduce the impact of chemical induced stress. Will not clog sprayers and is compatible with standard crop protection treatments.

NZBioAmino combines the benefits of seaweed with a comprehensive range of amino acids – the building blocks for efficient protein synthesis, naturally providing 9% organic nitrogen. 

The bio-stimulative and complexing power of NZBioAmino significantly increases mineralisation, availability and absorption of micro-nutrients leading to improved health, vitality and immunity of plants and soil biota. Amino acids form the foundation of plant cells. They improve the strength of cell walls and enzyme activity. Soil biology and plants use precious energy to synthesize necessary combinations of amino acids to form specific functional proteins. Having a ready supply of quality amino acids at key stages of growth helps support immune and defence mechanisms and enables plants to maintain the ability to recover and thrive as well as resist pest and disease pressure.

Directly applied to the soil, NZBioAmino supports and strengthens soil microbial communities enabling better nutrient uptake as well as promoting extensive, healthy root systems.

Foliar applications of NZBioAmino supports the structural, metabolic and mineral transport functions, improving chlorophyll production leading to improved photosynthesis and increased energy for growth, fruit set, ripening, seed fill and protein production.

At 9% organic nitrogen, NZBioAmino supplies nitrogen in a recognisable, high quality form that plants can utilise immediately. Used in combination with high analysis N-fertilisers, NZBioAmino can significantly reduce N-fertiliser use, improving production as well as reducing environmental impacts.

FruitGuard naturally supports high value crops during key periods of stress. The combined bio-stimulant qualities of seaweed, targeted key amino acids along with specific polyphenols and anthocyanins, together with secondary metabolites provide exceptional antioxidant and osmo-protectant capabilities for the protection against infection, disease and pests.

The powerful chelating properties of glycine betaine (GB) enhances efficient nutrient transfer and results in the release of digestible nitrogen. GB is a naturally occurring amino acid, however plants vary in their capacity to synthesise and accumulate it. Spinach and barley are examples of crop species that amass relatively high levels GB and therefore demonstrate natural cold tolerance characteristics.

Foliar applications of GB have shown to increase the status of low capacity GB crops that can better withstand adverse weather events and salt exposure, particularly during critical stages of growth and development.

The addition of secondary metabolites and polyphenols provide anti-pathogenic actions which naturally and rapidly accumulate at sites where infection occurs. Not only is FruitGuard an efficient cellular osmolyte, along with the collective nutritional support from seaweed and the disease fighting properties of polyphenols, it also stabilises and maintains the elasticity and integrity of cellular membranes - mitigating the damaging effects of inclement weather and increasing salt tolerance.

During critical growth and development phases and when periods of stress are anticipated, prepare your high value crops with the armour of FruitGuard and alleviate production pressure by enhancing plants’ natural prevention strategies. FruitGuard gives you reassurance for nil residue crops and has a zero withholding period.

Waikaitu® FishBoost is a unique blend of wild caught oceanic fish blended with nutrient dense brown kelp – both sustainably harvested from New Zealand waters. 

The combination of natural raw ingredients and high nitrogen content makes FishBoost a great choice of fertiliser and soil amendment for organic operations. FishBoost offers a source of burn-free nitrogen, along with many other primary and trace nutrients.

Healthy and productive soil contains billions of micro-organisms per kg.  These microbes break  down organic matter and soil components to liberate nitrogen and minerals in a plant-available form.  FishBoost is a mixture of biostimulative New Zealand brown kelp and proteins, enzymes and amino acids from oceanic deep water New Zealand fish. This blend produces a balanced and efficient fertiliser with all necessary nutrients to promote optimum soil health and plant growth.
