Our Customised blend of



Fine Particle Fertiliser

“The most efficient method of fertiliser and trace element application in New Zealand” says Dr Gordon Rajendram well know soil scientist. 

Taking even and accurate application of nutrients to the maximum, fine particle fertiliser has been proven for over 30 years by dairy, sheep, beef, deer, cropping, viticulture, and horticulture farmers.

Key benefits:

  • Customized mixes based on comprehensive soil testing
  • Macro, trace elements, bio-stimulants and seed in one application
  • Ideal for traditional, regenerative and biology farming systems

Application methods:

Applied by ground spread, Tow and Fert spreaders or aerial.


Granular Customised Blends

Mainfert specialises in customised granular blends.

We use sustainable, environmentally prudent products in our blends. Mainfert nutrient advisors take the time and care to work with our clients to present the most suitable blend that meets the needs of soil, plant, and animal.

Key benefits:

  • Individual mixes for block, paddock, crop or animal needs
  • Macro, trace elements and bio stimulants blended as required
  • Non soluble, non-acidic calcium-based products

Application methods:

Ground spread, client spreaders or aerial

We don’t shy away from recommending nitrogen as a strategic tool for promoting pasture or crop growth. Its how, when and what you use is important.

Mainfert have developed products based on common nitrogen fertilisers such as urea and ammonia sulphate that give the response but without the negative environmental, soil and animal health risks.

Key benefits:

  • Clients have reduced nitrogen use by up to 50% for same result
  • Natural inhibitors used to coat products and reduce volatilization

Application methods:

Groundspread, fine particle, liquid


Bio Stimulants / Humates

Mainfert understands that the key to good nutrient and soil management is to work with the three spheres of the soil – chemical, biological and physical.

The addition of bio stimulants to your fertiliser nutrient program will enhance the biological and physical parameters of the soil.

Key benefits: 

  • Utilise the infinite power of microbes, flora and fauna in the soil
  • Improve nutrient recycling
  • Direct animal administration available also

Application methods:

Ground spread, fine particle application, Tow and Fert spreaders, aerial


Multi Mineral Licks

A cost effective and proven way to enhance animal condition.

We manufacture our own mineralised licks, so we know what goes into them They are formulated to address mineral deficiencies immediately. Minerals are essential for animal health including disease resistance, fertility, production, weight gain and skeletal development.

Key benefits: 

  • Acts as nutritional buffer between an animal and its feed
  • Formulations for all classes of stock and fodder beet grazing
  • Palatable with balance of macro and trace elements


Garden Fertilisers

We sell a range of Garden Fertilisers available to collect from our Timaru branch:

  • Azalea & Rhododendron
  • Garden – vegetables
  • Tomato Mix
  • Lawn
  • Moss Remover
  • Rose

Innovative and sustainable fertiliser

The Result

Our fertiliser systems are designed to apply the nutrients required and at the same time encourage a healthier soil environment.

Our clients see dramatic changes in the soil structure, rooting depth and biological activity, which gives the returns needed from the fertiliser budget.

The above ground results are simply a consequence of getting the below ground system working like it should.

Flexible application options

Ground or Aerial Applications

When creating our custom fertiliser blends, we are constantly aware of using appropriate nutrients in correct quantities to achieve the maximum growth response without excess fertiliser use.

Accurate and even application avoids excess run off. Soil can be alive with millions of tiny creatures, ranging from earthworms to microscopic bacteria and fungi. The living soil feeds on dead and decaying plant and animal tissue and residues. After meeting its own requirements, these soil creatures then make available surplus nutrients from the decomposition of organic matter for plants growing in the soil.

An active soil life is therefore a critical component of soil fertility. It is the driving force behind the various nutrient cycles operating within a soil and helps to maintain the essential pool of plant available nutrients.

Regular applications of finely ground lime will maintain good soil structure, porosity and moisture status; ensuring both pH and soil nutrient levels are adequate.
