Fertilisers for New Zealand & Canterbury Pastures
We are a Canterbury business supplying NZ farmers with high-performance fertilisers and biostimulants (growth promoters), designed to support pasture productivity, soil health, and nutrient efficiency. Our range includes natural liquid fertilisers, seaweed fertilisers, NPKS and specialised blends, alongside humates and slow-release options. Our fertilisers help enhance pasture and crop production and reduce nutrient leaching. We also supply seeds and custom pasture mixes.
Rapid Boost NPKSÂ
Rapid Boost NPKS is a high-performance, fully soluble liquid fertiliser designed for rapid nutrient uptake and fast plant response. Built around a balanced NPK base with added sulphur and magnesium, it delivers quick, visible results across pasture, broadacre crops, and horticulture.
Its simplified formulation keeps costs down while ensuring reliable mixing, smooth application, and predictable nutrition, making it an ideal option for growers, contractors, and agronomy programs where consistency and performance matter.
Rapid Boost NPKS is particularly effective when plants need an immediate lift — supporting rapid green-up, recovery from stress, and sustained growth during key production windows.
Key benefits:Â
- Rapid foliar uptake – Bypasses soil lock-up for fast absorption and visible green-up
- Balanced NPK profile – Supports vegetative growth, root strength, and yield potential
- Sulphur enhanced – Improves nitrogen efficiency, protein synthesis, and leaf colour
- Magnesium enriched – Boosts photosynthesis and chlorophyll production
- Hassle-free application – Fully soluble, clean-mixing formula reduces blockages and downtime
Recommended application and dilution ratesÂ
Method: Apply to soil using flood nozzles or tow and fert
Rate: Use at 30L per hectare diluted with 60L water per hectare
Frequency: Apply 3 times per year, between September and March, during active growth period.
Stock stand down: No stand down period is required.Â
Available nationally.Â
Black Gold
Black Gold is a premium soil conditioner and biostimulant for farmers wanting long-term fertility gains. The formulation utilizes a proprietary carbon matrix to control nutrient release—specifically nitrogen—minimizing volatilisation and leaching.
Designed to feed the soil microbiology and maintain a healthy fungi/bacteria ratio, Black Gold includes a blend of marine peptides, amino acids, carbon and carbohydrates, creating a natural foundation for microbiomes to thrive in the soil. It also provides a natural nitrogen source, delivering nearly 2kg of nitrogen per hectare per season at a cost-effective price.
Key Benefits and Advantages:
This product enables reductions in conventional fertiliser by unlocking soil nutrient reserves, resulting in greater plant uptake of macro and micronutrients.
With its broad nutrient profile and balanced agronomic impact, Black Gold provides strong overall value and performance without the higher application or freight costs of competitor products.
- Promotes transfer of essential micronutrients to plants and animals, animals benefit by consuming treated areas
- Contains Zinc, Sulphur, Selenium, Magnesium, Iron, Copper, Cobalt, Calcium, and Boron - key elements for animal nutrition and health
- A balanced nutrient profile which boosts plant growth: provides 18 essential amino acids. Seaweed adds micronutrients and natural growth stimulants
- Reduces fertiliser needs: unlocks existing soil nutrients for plant uptake.
- Lifts soil carbon and organic matterÂ
- Enhances moisture retention and structure - biochar and carbohydrates reduce nutrient leaching and volatilisation
- Boosts microbial populationsÂ
- Improves overall nutrient cycling and plant availabilityÂ
Soil and climate suitability:
Suitable for all New Zealand climates and soil types.
Recommended application:
Application method: Apply to soil using flood nozzles or tow and fert
Rate: Use at 30L per hectare diluted with 60Lwater per hectare
Frequency: Apply 3 times per year, between September and March, during active growth period.
Stock Stand Down: No stock stand down period is required.
Apply via ground spread at a rate of 30 litres of Black Gold per hectare, diluted at a 1:2 ratio (1 part Black Gold to 2 parts water). For aerial application, use at a 1:1 ratio or apply undiluted.
Compatible with Tow‘N Fert systems and can be mixed with liquid urea or UAN for combined nutrient delivery.
Black Gold NPK
Black Gold NPK is designed to feed soil microbiology and maintain a healthy fungi-to-bacteria ratio, like Black Gold, but with an added boost of NPK to support rapid plant growth when needed. It is composed of:Â
- Marine Peptides
- Amino Acids
- Carbon
- NPK
These natural biostimulants help to establish a thriving microbial foundation, helping unlock soil nutrient reserves and enhancing plant uptake of macro and micronutrients. With 11.2% nitrogen, Black Gold NPK is ideal for promoting growth post-grazing or after challenging weather. The carbon component controls nutrient release, minimising nitrogen leaching and volatilisation, while the marine biostimulant provides essential micronutrients and growth stimulants.
Key features and benefitsÂ
- Soil health support: balances fungi-to-bacteria ratio for robust soil microbiology
- Controlled nutrient release: carbon minimises nitrogen leaching and volatilisation
- Improved nutrient uptake: unlocks soil nutrients for better plant absorption
- Micronutrient enrichment: trace elements and growth stimulants
- Enhanced growth: contains 18 amino acids and carbohydrate source, delivering 11.2% nitrogen to support vigorous plant growth after grazing or during challenging weather
Recommended applicationÂ
- Method: Apply to soil using flood nozzles or tow and fert
- Rate: Use at 30L per hectare diluted with 60L water per hectare
- Frequency: Apply 3 times per year, between September and March, during active growth period.
- Stock Stand Down: No stock stand down period is required

NitroBlack Boost
Available Canterbury only in bulk or bulk bags
Premium Coated Fertiliser with up to 20:1 Nitrogen Efficiency
Why settle for average when you can double your pasture response?
Independent NZ trials have shown that humate coated nitrogen delivers up to 20 kg of dry matter per 1 kg of nitrogen applied—nearly double the efficiency of standard urea or Ammo Blends.
That’s not just better growth—it’s better value, better soil health, and better environmental outcomes.
What Makes NitroBlack Boost Different?
- Carbon-coated nitrogen (humates) for improved uptake and reduced losses
- Elemental sulphur for slow steady release
- Magnesium added to support pasture resilience and animal health
- Reduced leaching and volatilisation—protects your investment and your land
- Optimised for NZ soils, especially Canterbury’s light, leach-prone profiles
Proven Results
Manufactured in Rolleston, our Canterbury farmers are already seeing the difference:
- Faster, stronger pasture growth
- Improved soil structure and microbial activity
- Better nitrogen retention—less waste, more gain
