|Hugh explaining the hot/aerobic composting technique used here on the farm.|
- chicken bedding (straw) and manure, from cleaning out the chicken house;
- grass cuttings;
- weeds from the vegetable beds;
- and kitchen scraps, vegetable peelings etc...
The chicken bedding acts as both a carbon-rich material (straw), giving structure to the compost and allowing ventilation, and a nitrogen-rich activator (chicken manure). Nettles are also a nitrogen-rich activator, while the rest of the ingredients act as "greens", providing energy to heat the compost and nutrients for the finished product.
For every two layers of "greens" added to the heap, we add one layer of "browns" (straw). The straw allows air to circulate through the heap, feeding the micro-organisms that enable fast hot composting. The heap will heat to 70-80 degrees Celsius, hot enough to destroy most weed seeds, and accelerate the composting process to make your compost ready for use within two months. The heap needs to be sufficiently damp, so watering is necessary at the beginning. Compost we made in early spring is already feeding the tomato, pepper, and aubergine plants in our polytunnel.
