Use of grape marc compost as substrate for vegetable seedlings

The effect of paper sludge and biochar addition on brown peat and coir based growing media properties

“…This fact suggests that the use of biochar could be an alternative to the use of compost obtained from pruning rest. Moreover, our GI values were also similar to the results obtained for grape marc compost, peat and sand by Carmona et al (2012).…”

Study of fat compost from dairy industry wastewater as a new substrate for pepper (Capsicum annuum L.) crop

“…The most frequently cited problems regarding the use of compost in the growing medium for vegetable transplants include unstable or immature compost, high soluble salt concentrations and poor water-holding capacity (Carmona et al, 2012). The principal requirement of compost for it to be safely used in soil is a high degree of stability or maturity, which implies a stable OM content and the absence of phytotoxic compounds and plant or animal pathogens (Bertran et al, 2004).…”

Mezclas de sustratos orgánicos e inorgánicos, tamaño de partícula y proporción.

“…Las variaciones de temperatura durante el proceso de composta destruyen a los patógenos y da origen a un producto estable e inocuo, de color marrón oscuro, inodoro y con olor a humus (Bernal et al, 2009). El compostaje puede utilizarse ya sea como acondicionador de suelos, como componente base para la elaboración de materiales orgánicos especializados o bien para mejorar la calidad del suelo agrícola (Bustamante et al, 2008;Carmona et al, 2012).…”
