Compost Turning Demonstration

Demo Field

New at Groundswell this year, the compost turning demonstration will be in the demo field. The aim of the process is to take a standard heap of farm yard manure and increase its worth by creating an environment in which beneficial biology, such as aerobic bacteria, fungi and protozoa can thrive. These micro-organisms then break down the organic matter in the manure creating a biologically active compost. When spread onto the field this not only acts as an organic manure, but also as a biological inoculant for the soil. Numerous components can be added to the mix, including wood chip or straw, with the aim of achieving a Carbon to Nitrogen ratio of approximately 25:1. Clay topsoil may also be added to provide additional nutrient binding sites. Ideally a temperature of between 50 and 70°C should be maintained by regular turning to provide the optimum environment for the beneficial microbes.
