The demand for the Terra Preta 70 substrate (based on composted biochar) is growing. This technosoil with its many qualities (infiltration speed, fertility, water retention, filtration, etc.) is used in particular for new urban planting. However, the manufacturing process is not yet standardised and the quality of the substrate depends greatly on the basic materials and the composting process. The Soils and Substrates competence group was mandated to support and accompany the company Pyrocycle in the development and production of terra preta 70% substrate and to evaluate its final quality.
