Building Soil Carbon

Soil is a living thing – it is a complete and self-sustaining ecosystem, alive with living organisms such as worms, fungi, insects, bacteria, and organic matter.
Watch this video to see how harmonious soil biology works.

Carbon is the main element present in soil organic matter (SOM) and is referred to as organic carbon. Organic carbon influences many soil characteristics including, colour, nutrient and water holding capacity, nutrient cycling and availability, improved water infiltration and aeration. It is a vital component of productive agriculture.

Soil carbon is an important indicator of healthy soil, influencing a range of factors that impact yield and quality. It is present as organic or inorganic carbon.

Increasing SOM also has another positive influence on the environment as it sequesters carbon (captures and stores atmospheric carbon dioxide carbon) in soils. It is estimated that SOM stores four times as much carbon as living plants and that carbon stored in all the world’s soils is two to three times the amount in the atmosphere.

When carbon sequestration becomes a focus, usually because of government policies and programs offering incentives, it is known as ‘carbon farming’ which focuses on adopting land management practices that increase the amount of carbon stored in soils.

BioAg’s focus is purely on working with farmers to improve their soil health for the long term, for improved pasture and crop yield and quality. Better soils. Better crops. Better stock.

Understand more about Soil Carbon – eLearn

Agriculture Victoria has developed a soil carbon eLearning module. It is a useful resource providing a great introduction for those seeking a better understanding of soil carbon, its role and function in agriculture.

How the Soil Carbon Sequestration Cycle works

Carbon naturally enters and leaves the soil through a range of complex processes occurring simultaneously. The amount of carbon stored in soils can be increased or decreased by changing and adapting land management practices.

  • Nitrogen supply through soils

    It is well known that soil microbes interact with plants to supply nutrients, in particular nitrogen, typically supplied through synthetic inputs such as fertiliser. In natural ecosystems, most nutrients including nitrogen (N) are bound in organic molecules which have l...

  • Is Nitrogen fertiliser burning a hole in your pocket and your soils?

    There is no doubt that high yielding crops, pastures and permanent plantings all require nitrogen (N). It is a major component of both chlorophyll, required for photosynthesis, and of amino acids, the building blocks of proteins.
