Sustainable forestry requires efficient regeneration methods to ensure that new forests are established quickly. In Sweden, 99% of the planting is manual, but finding labor for this arduous work difficult. An autonomous scarifying and machine with high precision, low environmental impact, a good environment would meet needs forest industry. For two years, collaborative group researchers, manufacturers, users (forest companies) has worked together on developing testing concept (Autoplant). The comprises several subsystems, i.e., route planning, driving (path planning), technology minimal automatic plant management, crane motion detection spots, follow-up. subsystems were tested separately integrated during field test at clearcut. shows great potential, especially from an perspective, significantly reduced soil disturbances, approximately 50% (the area proportion disturbed by disc trenching) less than 3%. Autoplant project highlights challenges opportunities related future development, e.g., relation between cost operating speed, sensor robustness in response vibrations weather, precision detecting size type obstacles planting.

Oasis agriculture revitalization and carbon sequestration for climate-resilient communities

Frontiers in Agronomy, Journal Year: 2024, Volume and Issue: 6

Published: April 24, 2024

Revitalizing oasis agriculture, an age-old human endeavor, has historically played a crucial role in sustaining biodiversity and ecosystems arid regions. Nevertheless, this enduring practice now faces contemporary challenges, including global warming, water scarcity, soil erosion, negative activities associated with urbanization. This comprehensive review delves into diverse literature across disciplines, covering topics such as conservation, restoration, agroforestry, Oasis Holistic Management, the aim of addressing these challenges. The analysis strongly advocates for urgent adoption sustainable practices, precision irrigation, polyculture, organic farming, community-based initiatives, to ensure survival agriculture foster long-term environmental social responsibility. study underscores imperative need development “comprehensive, flexible, forward-looking management strategies” guide revival farming. By consolidating information from various studies, it lays groundwork informed decision-making policy formulation. As part revitalizing agricultural ecosystem climate crisis, we propose noninvasive tool assessing carbon sequestration effectiveness based on tree specifications. Recognizing pivotal vegetation mitigating ecological impact facing crises, explored parameters influencing plant sequestration, biomass production, growth rate, longevity, root structure, leaf average temperature tolerance.

Experimental warming affects soil carbon dynamics in boreal and temperate forests: a meta-analysis

Environmental Research Letters, Journal Year: 2024, Volume and Issue: 19(10), P. 103002 - 103002

Published: Aug. 30, 2024

Abstract Boreal and temperate forests, spanning cold mid- to high-latitude environments encompassing about 43% of the global forest area, are highly vulnerable warming. Understanding response soil carbon (C) dynamics in these forests warming is paramount importance, yet significant uncertainty remains. In this meta-analysis, data from 97 studies across 65 sites were synthesized investigate effects on C inputs, pools, outputs boreal forests. Our results reveal that increased aboveground biomass (by 33%) litterfall 15%), while decreasing litter mass remaining 7%), with no change observed fine root biomass. Furthermore, led a 9% increase total respiration 15% autotrophic respiration, had discernible impact organic (SOC) content. The methods, magnitude, duration found regulate responses dynamics. Buried heater elicited most pronounced among methods. Additionally, exhibited an acclimation magnitude duration, decomposition rates SOC content microbial decreased escalating magnitude. Moreover, greater occurred than These findings underscore nuanced context-dependent nature experimental warming, providing critical insights for understanding role future climate mitigation strategies.

Soil Aggregation, Aggregate Stability, and Associated Soil Organic Carbon in Huron Mountains Forests, Michigan, USA

Forests, Journal Year: 2025, Volume and Issue: 16(2), P. 219 - 219

Published: Jan. 24, 2025

Soil organic carbon (SOC) plays a critical role in regulating the global (C) cycle, with forest soils serving as significant C sinks. aggregate stability and distribution of SOC different fractions would be affected by types. In this study, we investigate dynamics within soil across three main types Huron Mountains, Michigan, USA: white birch–eastern hemlock mixed forest, eastern-hemlock-dominated sugar maple forest. We hypothesize that variations species composition depth influence storage through mechanisms such root interactions, microbial activity, structure development. samples were collected from intervals (0–20 cm, 20–40 40–60 cm) analyzed for size content. The results showed stocks differ significantly types, exhibiting highest proportion large aggregates (>1.0 mm), which contribute to more stable structures. This type also had total mass mean weight diameter, indicating enhanced stability. contrast, displayed greater smaller lower macroaggregate-to-microaggregate ratio, suggesting fewer soils. closely linked size, macroaggregates containing SOC. These differences can attributed several underlying mechanisms, including plant physical properties soil. Forests diverse compositions, tend support complex systems communities, leading improved aggregation storage. Additionally, management practices selective thinning mixed-species planting these processes enhancing structure, increasing biomass, promoting health. interactions play crucial sequestration improving Our findings emphasized importance influencing stability, offering insights into study provided reference deeper understanding potential ecosystems supports development sustainable strategies mitigate climate change.

Published: Jan. 28, 2025

Evaluating SOC lability is crucial for sustainable agriculture policies and environmental quality. This study assessed the impact of well-stocked forest cover on pools compared to shrubby soil. Geo-referenced soils under Red pine (Pinus brutia), Black nigra), Cedar (Cedrus libani), Fir (Abies cilicia), Juniper (Juniperus excelsa), Oak (Quercus L.), Carob (Ceratonia siliqua), degraded shrubs were collected from a depth 0 30 cm in Seyhan River Basin, Mediterranean Turkey. The analysis soil organic carbon (SOC), AC (active carbon), PC (passive carbon) analyzed understand management across diverse vegetation types. forests have highest (27.98 g/kg) (27.35 g/kg), followed by (SOC: 27.64 g/kg, PC: 27.05 26.44 25.85 g/kg). Shrubby areas lowest (4.06 (3.61 had CLI (1.16), suggesting relatively higher proportion labile than other forests. CPI indicates greater storage capacity (1.09) shrublands (0.18), with also having CMI (0.83). findings emphasize critical role forests, especially sequestration climate change mitigation within Basin

Effect of Different Oak Forest Management Models on Seasonal Variability in Soil Properties at Sites with Igneous and Sedimentary Subsoil

Forests, Journal Year: 2025, Volume and Issue: 16(2), P. 350 - 350

Published: Feb. 15, 2025

Traditional forest management models could potentially be used to combat changes in environmental conditions by stimulating soil properties and supporting tree growth. In this study, we compare the effects of different oak (Quercus petraea /Matt./Liebl.) [coppice, coppice-with-standard, stocked coppice (reference)] on seasonal variability at upland igneous sedimentary sites (280–418 m a.s.l.). Soils were sampled 0–5 10–15 cm 50 × model reference plots January, April, July October between 2015 2019, organic matter, respiration, enzyme activity, pH water-holding capacity determined. The seasonality then compared using time-series analysis, analysis variance discriminant analysis. Overall, differentiated subsurface horizons from topsoil their feedback varied sites. While increased stands, acid phosphomonoesterase activity nitrogen content decreased site. most significant negative influence was observed site, greatest increase matter water holding registered coppice-with-standards Consequently, appropriate subsoil types valuable for improving carbon sequestration drought resistance.
