We began by building simple compost bins of recycled pallets and stakes.
The type and quantity of ingredients in compost matters. This will aid proper thermal decomposition, and an almost homogeneous product could be ready in 1 year.
The majority of the ingredients will be a mixture of greens and browns, with some existing soil to introduce a nurse population of microorganisms that will be breaking down the organic matter. This layering technique is then repeated and supplements can be added, like seaweed or minerals.
When the appropriate quantities of ingredients are used, and factors such as moisture and heat are not limiting, decomposition can occur effectively, and the core temperature of an effective compost heap can peak at 70degreesC!
Reaching this temperature is important, as harmful pathogens and weed seeds will be destroyed/denatured.
