“…Here, we expand our previous estimations of carbon sequestration by eucalypts with and without BC in Florida [15] by estimating (1) the economic potential for carbon sequestration by Eucalyptus planted in long-term mulch wood plantations, in more WBs, and in dendroremediation applications and (2) the responses to BC as a soil amendment with and without compost in additional field studies in Florida.…”

Growth and economic models for E. grandis in mulch wood rotations, for E. grandis and E. grandis x E. urophylla cultivars grown as short-rotation woody crops (SRWC), including coppicing, for E. grandis in windbreaks (WB), with and without soil amendments including biochar (BC) and the slow-release fertilizer Green Edge (SRF, GE), and for E. grandis in dendroremediation applications estimated the above- and below-ground carbon sequestration potentials of these management options. The cultivars may sequester over 10 Mg of C/ha/year as SRWCs. Under assumed management costs and market conditions, SRWC management with BC is more profitable than operational culture if BC application costs are ≤$450/Mg. Longer rotations with less intensive management result in lower but still considerable sequestration and economic benefit. In WBs, E. grandis cultivars may sequester up to 34 Mg of C/ha in 3 years, with additional sequestration by amending soil with BC, GE, and BC + GE. Amending soil with BC derived from eucalypts is both a long-term sequestration strategy and an opportunity to increase plantation and crop productivity. Demand for sustainably produced BC is growing due to multiple applications beyond soil carbon sequestration.

“…Through genetic improvement, high planting density, and intensive site amendments such as biochar [13], E. grandis cultivars may have maximum mean annual increments up to 78.2 green Mg ha −1 year −1 and sequester over 10 Mg of C ha −1 year −1 when grown as SRWCs [14]. Biochar increases soil carbon and productivity [15][16][17][18][19][20], which is especially important for the sandy soils common to central and southern Florida [21]. Soil amendment using biochar derived from eucalypts may therefore both enhance long-term carbon sequestration and increase plantation productivity [22].…”

Field drying Eucalyptus biomass can minimize the storage requirements, transportation costs, and/or the cost associated with biomass drying for biochar and other products. In central Florida, 12 6-year-old and 12 8-year-old Eucalyptus amplifolia and Eucalyptus grandis trees were field dried over two seasons, with two months of field drying in each season, and two tree forms (logs, whole tree). The whole tree average initial moisture content (MCod) on a dry basis ranged between 115 and 121% in E. amplifolia and 116 and 119% in E. grandis. The season and duration of field drying affected drying, but species, tree size, and tree form did not. In southern Florida, 19 3+-year-old coppice stems of an E. grandis × Eucalyptus urophylla hybrid clone (EH1) were field dried over two months of one season, with and without tree tops. The whole tree initial MCod ranged between 119 and 138%. The duration of field drying affected drying, but tree size and tree tops did not. Both studies suggest that field drying can effectively reduce wood MC and thus enhance E. amplifolia, E. grandis, and EH1 biomass quality.

“…Comúnmente estos cultivos se han establecido en suelos degradados y marginales, por lo cual han contribuido a la recuperación de estos sitios. Las especies más utilizadas pertenecen a los géneros Eucalyptus, Populus, Acacia y Salix, incluyendo también algunas gramíneas (Dahal et al 2022, Rockwood et al 2022; estas se caracterizan por presentan gran capacidad de adaptación y rebrote (Ríos-Saucedo et al 2017). El manejo de la densidad de plantación es un factor crítico que puede condicionar en gran parte el éxito en términos de rendimiento en biomasa en este tipo de cultivos.…”
