Soil carbon sequestration is like a poker machine

Microbes do most of the work to decompose organic matter which is added to the soil. They take carbon from the soil organic matter and respire about two-thirds of it as CO2, which then escapes to the atmosphere. The microbes use the rest of the carbon to grow and divide and so the microbial biomass builds up in the soil and essentially become part of the long-term pool of soil organic carbon.

The carbon going into the soil organic carbon pool is impossible to see and difficult to measure, in the same way that the money flowing from the poker machine to the bank is hidden. In contrast, the carbon which is lost as CO2 escaping to the atmosphere is easy to quantify with simple colour-change tests, just as the pay-out from poker machines can be seen by the punter because it is trumpeted by bells and whistles.

The peculiar aspect of the analogy is that CO2 emissions to the atmosphere affirm that the microbes are active, and that soil carbon sequestration is happening. Great news – which provides encouragement enough to keep adding organic matter to the soil. And as long as organic matter is added, the microbes will keep taking small amounts of carbon into the long-term soil organic carbon pool. It is a perverse winning strategy.

AgSight to again sponsor the AORA conference in 2023

The 2023 Australian Organics Recycling Association conference is being held from 7-9th June at the Pullman Albert Park in Melbourne. Invitations for Program Proposals close on 14th February www.aoraconference.com.au. We like the shift in topics towards the end-users’ perspectives about compost and the potential for market growth using recycled organic products.

AgSight will again be there to continue our support for AORA and the compost industries across Australia. Keep an eye out for our bright yellow lanyards featuring the Solvita™ brand.

Solvita Maturity Testing technologies play a key role in the making of good quality composts and the Solvita Soil Health tests allow farmers to see the benefits that composts bring to their soils and crops.

I look forward to catching up with everyone at the conference. In the interim, keep active, and please contact us to purchase Solvita products and discuss our Agricultural Research and Technology services.
