If you are looking to increase your soil organic carbon, why not consider making your own on-farm compost solution? Composting is an aerobic method of decomposing organic solid wastes that can be used to recycle organic material. The process involves decomposing organic material into a humus-like material, known as compost, which is a good fertilizer for plants and is excellent for increasing soil ‘health’.

Decomposition involves physical decomposers like worms, beetles, ants, millipedes and other chewing invertebrates grinding, tearing, chewing, and digesting organic material into smaller fragments, which are then available to the chemical decomposers. Chemical decomposition is undertaken by natural bacteria, fungi and protozoans (remember them from school – they are tiny single celled organisms) which release and recycle organic nutrients including carbon, nitrogen, phosphorous and trace elements.

Creating an on-farm compost row is a good option if you have access to a regular quantity of organic material – particularly animal waste from cows, chickens or sheep, which is often a by-product of agricultural production. You will need somewhere to mix up the material to maintain the right air and water levels. This is exactly what Blythe Calnan from Uduc has done with help from PHCC’s Greening Farms program.

By creating a mix of manure, woodchips, hay and other organic materials, and adding a few thousand worms, Blythe has successfully begun a self-composting windrow which produces fresh compost directly, as well as creating a compost tea which can be spread on her property to increase soil microbial activity and organic carbon levels. Blythe is even able to feed her compost windrow organic-bamboo spoons and forks from her farm field days!

Having an on-farm, local source of carbon-rich, biologically active fertiliser is an excellent resource for any farmer looking to enhance the health of their soil. It also reduces fertiliser cost and increases the sustainability and resilience of farms, as they rely less on external markets to grow their produce.
