Partial Replacement of Peat: Effects on Substrate Physico-Hydrological Properties and Sage Growth.

ABSTRACT: The transformation of organic by-products derived from waste into value-added resources represents a promising strategy to advance circular economy principles and bolster environmental and agricultural sustainability, especially in soilless cultivation. This study evaluates the viability of three organic by-products-wood fiber (WF), coffee silverskin (CS), and brewer's spent grains (BSGs)-as partial peat replacements in horticultural substrates. Ten growing media formulations were assessed, incorporating increased doses (0-40% v/v as peat replacement-PR) of each alternative by-product. The effects on physical and hydraulic substrate properties, along with plant growth traits, were examined using two ornamental Salvia genotypes, 'Victoria' and 'Amistad'. To synthesize t
