What we do...

Soil improvement products. 

Soil Trooper is a pure source of the native soil fungus Nigrospora oryzae

Used as a soil ameliorant, Soil Trooper assists with the breakdown of organic material on the soil’s surface, and helps to store organic carbon in the soil where it is needed.

Compost tea making equipment.
We supply 450 micron mesh bags that are just perfect for brewing compost tea. We’re also very experienced at building low cost compost tea brewers in a size to suit your requirements. Talk to us about it.


Farmer-friendly microscopes, suitable for assessing compost teas and identifying soil microorganisms. Let us know if you can get a better price on microscopes like these! We also have some spare parts and quality replacement objectives and lenses for this style of microscope. The 60x objective and 15x lens combine to give great magnification without the need for that messy immersion oil. Contact us if you’re looking for a part, we just might have it.


What happened to Parra Trooper?

“Parra Trooper” was the original name given to the Nigrospora oryzae native fungus product developed by Beechwood Biological Solutions. 

We’ve seen a fair bit about it in the news since the APVMA decided the native fungus was an “unregistered agricultural chemical” and couldn’t be promoted or supplied for the purpose of controlling Giant Parramatta Grass and other closely related Weedy Sporobolus Grasses. So, it’s back to transplanting infected plants to spread Nigrospora oryzae if your intention is to control weedy Sporobolus grasses .


Soil Trooper is a pure source of Nigrospora oryzae native soil fungus to be used only as a soil ameliorant.

Please be aware that “Parra Trooper” has no relationship whatsoever to the herbicide “Para-Trooper”.  We held our trademark before they applied for theirs, that’s all.  These are two very different products.  One of them has been nominated for an international Organic Farming Innovation Award and received an Australian Government Landcare award for innovations in sustainable agriculture; the other has not.
