Not all composts are created equal. This is a largely misunderstood fact because there is no test for biological quality which is the true value of good compost. There is a massive difference between the bags from the nursery and what a well made Bio-complete compost can do. It goes against common belief but in fact you can produce a far higher quality of compost if you follow a method that has been proven to consistently produce the highest biomass of the right types of microbes. 

The best way to turn your waste into soil regeneration is through composting. This is about turning waste streams into a microbially rich inoculation to kick start soil regeneration.

The value of compost lies in its microbial biomass and whether the right community of microbes is present in the right quantities. Bio-complete is a qualification of quality for a compost to achieve, it means the right levels of mirobes are present. To be labelled Bio-complete a sample must be assessed by one of our microscope specialists to determine if it is Bio-complete. This is calculated by looking at the biomass of each functional group in the Soil Food Web , if the sample has the right numbers for each group it can be qualified as Bio-complete.  

Knowing if the compost is Bio-complete is important whether you are buying it or making it yourself. Only by determining the biomass of the different microbial groups can you be sure that you are getting all the right microbes in your inoculum. All the benefits that soils can provide are linked to the biology within them, ensuring that the right biology is there is crucial to the success of any soil system. 


This process uses the enzymes and heat generated by active microbes to decompose organic matter. The heat comes from the rapidly multiplying microbes, with the right conditions each bacterium will replicate every 10-20 minutes. This population explosion will quickly heat up and decompose the available organic matter in a pile. If done right this can leave you with a well-broken-down and microbial-dense compost to use.

This process makes use of one of the organic gardener's greatest allies, the worm. We call them composting worms and there are number of species which fall into this group. The main function they provide is assisting the back down of organic matter. Compost that has been worked by worms will have the most beneficial species of bacteria and will be free of pathogenic microbes. The worm casting is well known for the many benefits provided to soils.
