Bioenergy Production From Sugarcane Straw: Implications for Soil‐Related Ecosystem Services

GCB Bioenergy, Год журнала: 2025, Номер 17(5)

Опубликована: Апрель 8, 2025

ABSTRACT Sugarcane straw removal for bioenergy production—especially second‐generation ethanol—is shown to be a promising pathway decarbonization. However, indiscriminate can negatively affect soil‐related ecosystem services (SES), compromising the sustainability of associated production. Here, comprehensive literature review was conducted select and quantify changes in agronomic environmental indicators affected by low (≤ 1/3), moderate (> 1/3 ≤ 2/3), high 2/3) levels consequential impacts on eight SES. A quali‐quantitative approach developed generate an impact matrix that provides direction effects (negative, neutral, or positive) confidence levels. Overall, lowest SES occurs under with neutral effect C storage, nutrient cycling, weed control, greenhouse gas (GHG) mitigation, provision food bioenergy. Water regulation, erosion maintenance soil biodiversity were most removal. Moderate compromise sugarcane cultivation areas, except pest control GHG emission mitigation. Finally, it also discussed how negative could mitigated even reversed through adoption best management practices, such as cover crops, organic amendments, biological products (e.g., use phosphate‐solubilizing bacteria mycorrhizal fungi), reduced tillage, machinery traffic control. Ultimately, results this study useful guide decision‐making farmers, investors, stakeholders, policymakers toward sustainable production contributes low‐carbon economy climate change

Nitrous Oxide Emissions and Ammonia Volatilization from Pasture after Cattle Dung and Urine Applications in the Dry and Rainy Seasons of the Brazilian Cerrado

Agronomy, Год журнала: 2024, Номер 14(6), С. 1257 - 1257

An important source of greenhouse gases in Brazil is the nitrous oxide (N2O) emission from pasture, and microorganisms play an role nitrogen transformations soil. This study aimed to evaluate N2O NH3 volatilization bovine excreta pasture integrated crop–livestock system (ICL) Brazilian Cerrado. Three treatments (urine, dung control) were performed two pastures (Area 1—three-year Urochloa ruziziensis Area 2—one-year brizantha cv. Piatã), with application times (dry rainy season), during successive years application. Compared control, deposition on ICL increased soil fluxes. In dry season, fluxes associated higher ammonium (NH4+) availability. these related NO3− availability water-filled pore space (WFPS). both areas, was after urine than application, especially season. The highest factors obtained for (0.32%), season (0.36%), older 1: 0.24%). All values below mean IPCC default (0.77%). These results indicate that emissions should be evaluated regional conditions.

Abstract The efficient use of vinasse, the primary byproduct sugarcane ethanol production, is important for economic and environmental sustainability industry. Few studies have quantified soil health response to long‐term vinasse application, even though this generally applied as a potassium (K) source in fields. Soil Management Assessment Framework (SMAF) was used assess integrated soils with contrasting textures. Chemical, physical, biological indicators were selected, measured, into index clay‐ sandy‐textured Brazil. Overall, application improved components both soils. results showed that benefits go beyond increasing K content. Vinasse increased organic carbon content, nutrient recycling, physical quality. from 49% 62% clayey 43% 61% sandy clay soil. findings therefore revealed potential reduce need synthetic fertilizer promote circular economy regardless type. This study verifies sandy‐ clay‐texture Brazil has because it recycles an enhances health.
