Use of Solid Digestate as Growing Media for the Production of Horticultural Crops

Peat is the principal component used for growing media of horticultural crops due to its agronomic characteristics. On the other hand, is a nonrenewable material (Herrera et al., 2008). Previous researches indicated the compatibility of some renewable composted organic wastes in mixture with peat-based media (Herrera et al., 2008; Ronga et al., 2016). However, the composting process might increase the GHGs emissions (Lim et al., 2016). Thus, the aim of this work was to evaluate the use of anuntreated solid digestate as a component in the formulation of growing media for the seedling production of two crop reference species: tomato and basil.
