Soil Foodweb

New Zealand

Soil Foodweb NZ are the foremost soil testing laboratory for micro-biology.  Much of what we base farm production on relates directly to the soil microbes.  Knowing what levels of soil biota exist in our soil and how active they are allows farmers and gowers to optimise their production systems.

In January 2003 at Dr Elaine Inghams invitation Cherryle’s training was completed at the Soil Foodweb Labs in Lismore, Australia and Covallis, USA after which she opened the NZ laboratory.

Since its inception in 2003, Soil Foodweb Institute NZ (SFI NZ) has been working with 10’s of thousands of agriculture and horticultural growers throughout both islands of New Zealand to help them improve the health and productivity of their soils.  The laboratory now operates out of Hanmer Springs, North Canterbury in the South Island.

Understanding how the microbes effect soil health and plant production requires a detailed knowledge on what organisms exist in the soil;

  • How many of them are active and doing the job
  • How well their actions are cycling nutrients
  • If the balance between fungi and bacteria are suitable for the crop
  • Their trend of growth ie more bacterial or more fungal

At Soil Foodweb NZ, the team are able to assess soil, compost, vermicast and various other biological products for fungi, bacteria, protozoa, and mycorrhiza. Armed with this information you are then able to confidently decide on the right management tools and weigh up how effective they are over ensuing years. Working with many input suppliers and consultants we are able to adapt the farmers existing nutrient programs to facilitate a smooth transition from ‘mineral-only’ replacement to biological production/regenerative farming.


Since its launch, Soil Foodweb NZ has been working with tens of thousands of agriculture and horticultural growers throughout both islands of New Zealand to help them improve the health and productivity of their soils.

“Just wanted to get in touch to say thank you very much indeed for the two field workshops you ran for us and Avoca last week. It was lovely to finally meet you. I very much enjoyed your presentation and again added to my knowledge about things biological farming. I particularly appreciated your clear explanation of the bacteria/fungi ratios in various soils & what that indicates, and therefore how to remedy problems.”
