Farm Manager & Vet Robyn talks about the farming business case for composting
In the area around Robyn’s dairy farm in south east Queensland compost was rarely used in commercial agriculture, especially in dairy and feed lots with high manure surpluses. In this video Robyn talks about the challenges and lessons she has learnt about using manure surplus, to increase soil quality and fertility in a sustainable way. She believes that compost is the most effective way of improving soil long term with clearly beneficial effects on soil quality, stock health and farm profitability.
Robyn also addresses standard modern Australian agricultural practices such as the heavy use of mineral additives and chemical fertilisers, frequent soil tillage, fast crop rotations, and huge shifts in land and how this has greatly decreased soil organic carbon (SOC) stocks, leading to bio diversity loss, faster soil erosion, and pollution of groundwater and air.
Robyn is a vocal advocate of the importance of composting is an tool having witnessed first hand how healthy soil creates healthy plants, which creates healthy plants, stock and humans. The benefits of compost are clear including: improving drainage and nutrient availability in clay soils, improving water and nutrient holding capacity of sandy soils, helping neutralise pH of both acidic and alkaline soils and lastly that many toxins are broken down in the composting process, while others such as heavy metals in city soils become locked up and less available to plants when compost is added.
This is the story of the real journey of compost discovery, the effects and benefits and watching the farm and it’s live stock and the herds milk and health change over the years. Seeing with her own eye that the cattle preferred to graze in the paddocks that had been treated with compost and would walk past other grass to do so.
