Today marks World Soil Day, probably the most exciting day in my calendar (being the founder of a software company that maps and measures soil). This year our announcement makes it even more special. Today we launch our mission to help 1 million farmers sequester 1 billion tonnes of CO2 from the atmosphere by 2025, roughly equivalent to removing 217 million cars from the road in that same time.

After it was announced by Agfundernews yesterday, I wanted to spell it out below in some detail to help others understand how agriculture can be used to not just kerb, but…


As the world shifts to a carbon-neutral future, carbon credits are becoming increasingly important in helping companies offset their emissions. Agriculture offers a major opportunity to produce these credits, especially through what I’m most excited about: soil carbon sequestration. There are some fundamental challenges when it comes to the generation of credits though, including whether we use a modelled or a measured approach. Here I discuss the advantages and disadvantage of each, specifically in terms of the ‘proof of work’ required to validate and authenticate credits produced under each approach.

Carbon Credits 101

Firstly, some basics. A carbon credit is…


AgTech companies are critical in helping develop scaleable and commercial systems to better incentive growers

Key points:

  • Agtech needs to support a range of different models and techniques for soil carbon measurement that suit the areas, demographics and agricultural industries they operate in.
  • The King Review recently recommended subsidising the cost of measuring carbon abatement, and introducing methods to favour small scale farm operations.
  • Reducing the cost of soil carbon projects is critical, as is scale. Since 2012 only 78 Agriculture ERF Projects have been registered in Australia.
  • Agtech companies are critical in helping develop scaleable and commercial systems to better incentive growers.
  • To highlight the value of soil carbon, soil carbon measurement platforms need…
