Soil is one of the largest and most important Carbon sinks on the planet. Use of artificial fertilizers and pesticides in intensive farming has slowly degraded the health of the soil to the point where it holds little organic matter and is close to becoming lifeless. At the same time pollution and GHG emissions from fertilizer manufacture and use and mis-management of manure are causing huge damage to soil, water and the climate.
The THREE C project proposed a new management system to use Biochar as part of a circular nutrient capture system for small farms. This will help farmers to trap and preserve valuable nutrients and organic matter from animal manure and bedding and convert them to a rich compost/biochar mix that is easy to store and apply.
The Biochar Co-composter adapts a simple, low-cost design to handle this material and adds simple automation so that it can be easily fitted into daily farm management with little disruption.
The Composter serves as a tool to help:
