The liquid you make from this process is referred to as a ‘tea’, mainly because of the brewing process in the water. Our ‘microbe tea’ contains microbial food sources and a range of cultured microorganisms instead of compost, but does not need brewing like aerated compost tea.
How is it that no brewing is needed?
Our approach with Biosys is similar to making and using a compost extract rather than brewing a compost tea.
If you do your research into compost tea, you will soon find out that many experienced makers and users of compost teas now have two general approaches; brewing for foliar spraying and extracting for soil or growing media application.
Brewing aerated compost tea in water with microbial foods is typically done for 24-48 hours with the intention of multiplying the microbes in the solution. Making a compost extract involves adding the compost to water, aerating or simply stirring and agitating the compost for around 15-30 minutes, then add some microbial food sources and apply immediately to the soil.
When making an extract, the goal is to knock the microbes off the compost and put them into a solution so they can then be dispersed onto the soil and become active in the root zone.
