A large audience of farmers, graziers and community members attended.

A CCL spokesperson said Dr Orgill's speech emphasized that more soil carbon is a win:win for everyone.

"She advised about changing practices to increase soil carbon and considerations for trading carbon credits," the spokesperson said.

"She said by managing plant nutrition and grazing practices, the accumulation of soil organic carbon substantially increases. Increasing soil carbon means better production, better water retention, more biodiversity plus taking carbon emissions out of the air.

The more plants that are growing, the more carbon is being pumped into the soil.

"Fresh and partially broken down organic matter, known as particulate or carbon drives microbial processes and is the most sensitive type of carbon to land management," Dr Orgill explained.

"Humus is an important form of stable carbon, that stores soil nutrients.

"Managing plant nutrition and strategic and rotational grazing management can substantially increase the accumulation of soil organic carbon."

She provided advice on changing practice to increase soil carbon and considerations for trading.

Many stayed behind after the lecture to chat and catch up. The CCL thanked the NSW Department of Primary Industries for supporting the event as well as the Goulburn Soldiers Club for the venue.

The next CCL event will be at the Goulburn Soldiers Club, on September 5, when Phil Graham will speak on 60 years of local weather and what 2030 will look like in the Southern Tablelands.
