Latest science on soil carbon

There are many ways to increase soil carbon while also increasing productivity, water holding capacity and nutrient cycling.

Agriculture Victoria is encouraging farmers to download a new online booklet to learn more about the latest soil carbon science.

The Soil Carbon Snapshot booklet is one of a number of tools being developed to support farmers to reduce their on-farm emissions, manage their climate risk and improve productivity.

Agriculture Victoria land health project leader Melissa Cann said there were many ways to increase soil carbon while also increasing productivity, water holding capacity and nutrient cycling.

“Increasing soil carbon will reduce input costs and produce wider natural resource management benefits,” Ms Cann said.

“If you are trying to better understand the fundamentals of soil carbon in agriculture, this is a great resource to start your journey.”

The free, updated booklet includes 70 references to soil research papers, abstracts or reports – all hyperlinked for easy access and use.

“Soil organic matter makes up a small component of the soil mass, yet it has an important role in the functioning of the physical, chemical, and biological properties of soil,” Ms Cann said.

“Soil organic carbon is a measure of the carbon contained within soil organic matter and increasing soil carbon levels can lead to better plant establishment and growth.”

Ms Cann said the original booklet was written by Agriculture Victoria in 2013 as part of a program to summarise the latest science on soil carbon, as a resource for Fertilizer Australia and its national Fertcare advisor training program.

“With the current renewed interest in soil carbon, it was time for an update.

“Fertilizer Australia, in partnership with the International Fertiliser Society, also recently ran a series of webinars with expert speakers and had this updated booklet available online as a timely resource for those keen to understand the latest science.”

Agriculture Victoria is helping the agriculture sector respond to climate change and reduce emissions through its Agriculture Sector Pledge program, conducting research trials to test methane inhibiting feed additives and delivering an innovative pilot involving 250 farm businesses in a free, on-farm emissions assessment.
