| Abstract | The use of biochar (BC) as a soil amendment has attracted much interest with regard to increasing soil carbon sequestration, improving soil fertility, and increasing crop production. However, studies to date show a great variability in their results, depending on the plant species studied. Moreover, the effects of BC addition on the roots are not well understood. We investigated the effects of a BC, obtained from olive-tree prunings and applied to soil at 5% w/w, on soil properties, root morphology, and crop yield in a greenhouse pot experiment. We used eight species of agronomic interest: Brassica napus L., Capsicum annuum L., Cicer arietinum L., Glycine max L., Gossypium herbaceum L., Solanum lycopersicum L., Solanum melongena L., and Zea mays L. Addition of BC reduced soil bulk density and increased both soil water content and nutrient availability, as well as increasing the specific root length. It also increased aboveground biomass, specific leaf area, leaf relative water content, and both seed and fruit production, the latter being positively correlated with the specific root length changes. Most species responded positively to the addition of BC derived from olive-tree prunings, the response being directly related to changes in root traits.
