The Vermiculture venture

IITSV started stated as a personal quest in 2013 when we purchased our land on Oxley Island where I had intended to grow organic vegetables for the local market.IMGP0045-001

This is marginal land,  however it is in a great scenic coastal location and affordable for our small family.

Immediately, we knew if we were to successfully grow crops we had to improve the organic content, address the mineral imbalances and generally enrich the biologically bereft soils in order to make this land productive.

We explored various methods of soil improvement, including growing and mulching green crops, adding compost, applying compost teas etc. most of which were either too expensive or nonviable.

Whilst attending a field day at a local Wildflower farm what we saw really opened our vision to the vast opportunities and the enormous benefits of adding biology through living microbes.

This is when I became fascinated by the work of the humble compost worm.


Vermiculture is a relatively uncharted industry.  In the beginning I sought out and talked to as many people with knowledge and experience in the field as possible,  attended seminars with visiting consultants and read everything I could get my hands on.  There is a limited amount of published material available, some of which I have found to be unreliable.  First and foremost I needed to understand the working of the humble worm and sort out which were the best workers in our climate and local conditions. Our aim was to develop an efficient,  viable and workable system to achieve the highest quality product available.

I set up my own mini laboratory, studied and observed and based on the findings of my research and field trials I gained many insights and understanding into the future of working with the humble worm. Needless to say…I was hooked..!

From an initial purchase of 10 kg of mixed compost worms and 1 worm bed under a shady tree we have grown the business into a 600m2 greenhouse containing 30 stacking beds, 6 floor beds and 2 x 19 metre long mechanised cast harvest beds which, when combined hold close to 1 tonne (4,000,000) of worms all working very efficiently to create beautiful worm cast.


From there our business has grown to be a leading supplier and manufacturer of liquid vermicast biostimulants and associated products.


Our signature product, Biocast+ liquid biostimulant is achieving great results in many and various fields of horticulture, agriculture,  floriculture, landscaping and home gardens.

We understand that we have an enormous role to play in educating the various sectors of both the ornamental and amenity horticultural industries.

We cannot for a moment, underestimate the importance and effectiveness, or the incredible advantages of simply adding living biology to soil. It is not a one or the other approach, we can not only consider nutrients in isolation from biology or vice versa.

The role of biology is vital to the availability of minerals to plants.

With this new knowledge and understanding it is obvious that many of the old ways of farming are no longer either viable nor productive, we aim to educate, dispel and challenge some firmly held views on the simple but intricate nature of soil management in order to improve growing systems and productivity over time.

At the same time, we are confidently  creating a standard bench-mark for the future of organic waste disposal, by turning waste products into an amazing, willing,  powerful workforce of living biology.
