Use of biochar as peat substitute for growing substrates of Euphorbia × lomi potted plants

2016

Biochar from conifers wood was used in soilless culture as growing substrate alternative to peat for ornamental crops. Potted plants of Euphorbia × lomi Rauh cv. ‘Ilaria’ were grown with different mixtures (v:v) of brown peat and biochar in order to evaluate main physical and chemical characteristics of this biomaterial as well as its effect on plant growth, ornamental characteristics and nutrients uptake. Biochar addition to peat increased pH, EC and K content of the growing substrates, as well as air content and bulk density. Biochar content of substrates significantly affected plant growth and biomass partitioning: higher number of shoots and leaves, leaf area and leaf dry weight were re…

Biowaste in a circular bioeconomy in Mediterranean area: A case study of compost and vermicompost as growing substrates alternative to peat

2020

European policies are advocating a transition toward circular bio-economy, an economy aiming at reducing the dependence from fossil-based resources, limiting greenhouse gas emissions and environmental impacts. The aim of this paper is to assess the potential for circularity for bio-waste and related by-products, to highlight the role of compost and vermicompost in the circular bioeconomy and their use in the agricultural sector. Three different substrates were tested in the soilless cultivation of Salvia officinalis, a Mediterranean nutraceutical and healthy plant: vermicompost (40%), compost (40%) and peat (100%). The average values of the main biometric parameters were calculated and comp…

Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems

2020

Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing th…
