- Evaluación de biochar como alternativa de sustrato en cultivos de tomate Margarita Gallo-Saravia Luis Lugo-Sierra Rolando Barrera-Zapata Ingeniería gro Biochar tomato culture small scale crop industrial wastes The thermochemical transformation of biomass, i.e., to generate electrical power, produces a solid residue named biochar. Biochar properties allow using it in different applications, including soil amendments. In this work, two specific types of biochar are evaluated as potential substrate substitutes in open small-scale cultures. A crop of Solanum lycopersicum (tomato) was used as reference, and the effect on plant development and harvest (number, diameter and weight of fruits) was observed when replacing the commercial substrate by biochar in proportions of 0, 20, 50, 80 and 100%. It was observed that with substitutions of 20% and 50% of substrate by biochar, the plants show a normal development and the tomato production is comparable to the one obtained in the absence of biochar; However, when replacing 80% or 100% of the substrate by biochar, the effect on plant growth is negative, apparently due to the absence of nutrients. From an economic and environmental perspective, these results are quite satisfactory; since using 20% or 50% of biochar can represent significant savings for the farmer (less use of substrates), while also giving utility to agro-industrial waste (biochar). 2018 artículo científico 0122-1701 https://www.redalyc.org/articulo.oa?id=84958001022 https://www.redalyc.org/journal/849/84958001022/ https://www.redalyc.org/journal/849/84958001022/html/ https://www.redalyc.org/journal/849/84958001022/84958001022.epub https://www.redalyc.org/journal/849/84958001022/movil https://doi.org/10.22517/23447214.17691 es http://www.redalyc.org/revista.oa?id=849 Scientia Et Technica application/pdf Universidad Tecnológica de Pereira Scientia Et Technica (Colombia) Num.2 Vol.23
