“…These results differed from those of Gardi et al (2016) who stated that the soil carbon density would differ for various farming methods. We found higher mean carbon density in the 0–30 cm soil layer of permanent grassland as compared to arable land at both farms, which is consistent with the findings of Balasubramanian et al (2020) and Gardi et al (2016). Mean soil carbon density in coniferous woodlands was slightly, but not statistically significantly, higher compared to broadleaved woodlands on the two farms in this study, and this was also observed for Scottish forest soils (Vanguelova et al, 2013), forest soils in Great Britain (Reynolds et al, 2013) and parkland soils in southern Finland (Heikki Martti et al, 2016).…”

“…At Nafferton Farm, we found similar soil carbon results to Zani et al (2020) even though the soil sample processing steps and soil carbon determination method differed slightly between the two studies. One reason contributing to the greater amount of carbon of GB soils overall as compared to our results is the occurrence of peat‐dominated soils in Wales and Scotland because of higher rainfall, which facilitates carbon sequestration (Balasubramanian et al, 2020; Guo & Gifford, 2002). Average rainfall from 2015 to 2019 was 1147 mm in GB, 902 mm in north‐eastern England, 1560 mm in Scotland and 1461 mm in Wales, respectively (Metoffice).…”

Many institutions have substantial landholdings, but few consider soil carbon preservation and augmentation in their carbon management plans. A methodical framework was developed to analyse terrestrial carbon stocks (soil and tree biomass) for credible carbon offsetting strategies in institutional land. This approach was demonstrated at two farms (805 hectares) managed by Newcastle University. Soil carbon for three depths (0–30 cm, 30–60 cm and 60–90 cm) and above‐ground tree biomass were quantified. These data provided a terrestrial carbon baseline to evaluate future land management options and effects. Historical land‐use records enabled the following comparisons: (1) agricultural land vs. woodland; (2) arable land vs. permanent grassland; (3) organic vs. conventional farming; (4) coniferous vs. broadleaved woodland; and (5) recent vs. long‐established woodland. Carbon storage (kg/m2) varied with land usage and woodland type and age, but only agricultural land vs. woodland, and for agriculture, arable land vs. permanent grassland, significantly affected the 0–90 cm soil carbon. At the university‐managed farms, current terrestrial carbon stocks were 103,620 tonnes in total (98,050 tonnes from the 0–90 cm soil and 5,569 tonnes from tree biomass). These terrestrial carbon stocks were equivalent to sixteen years of the current carbon emissions of Newcastle University (6,406 tonnes CO2 equivalents‐C per year). Using strategies for alternative land management, Newcastle University could over 40 years offset up to 3,221 tonnes of carbon per year, or 50% of its carbon emissions at the current rate. The methodological framework developed in this study will enable institutions having large landholdings to rationally consider their estates in future soil carbon management schemes.

“…the amount of carbon that is assimilated by plants, is a primary driver of soil carbon dynamics. Other studies found unchanged or even decreased SOC stocks upon the increased cutting frequency with biomass removal (Balasubramanian et al, 2020;Kramberger et al, 2015), which might point to the fact that the found SOC sequestration was mainly achieved by leaving the clippings on site. Leaving the clippings on-site might in turn stimulate N 2 O emissions, which could potentially lead to a certain greenhouse gas trade-off of SOC sequestration.…”

Soil organic matter is the largest terrestrial carbon pool. Globally, it stores more carbon than vegetation and atmosphere combined (Ciais, 2013). Relatively small changes in soil organic carbon (SOC) stocks can thus have strong impacts on the atmospheric CO 2 concentration. For this reason, accumulating SOC is considered as a potential negative emission technology to achieve international climate mitigation goals. Furthermore, soil organic matter content is a key soil quality indicator, due to numerous positive effects of organic

In recent years, the application of unmanned aerial vehicle (UAV) remote sensing in grassland ecosystem monitoring has increased, and the application directions have diversified. However, there have been few research reviews specifically for grassland ecosystems at present. Therefore, it is necessary to systematically and comprehensively summarize the application of UAV remote sensing in grassland ecosystem monitoring. In this paper, we first analyzed the application trend of UAV remote sensing in grassland ecosystem monitoring and introduced common UAV platforms and remote sensing sensors. Then, the application scenarios of UAV remote sensing in grassland ecosystem monitoring were reviewed from five aspects: grassland vegetation monitoring, grassland animal surveys, soil physical and chemical monitoring, grassland degradation monitoring and environmental disturbance monitoring. Finally, the current limitations and future development directions were summarized. The results will be helpful to improve the understanding of the application scenarios of UAV remote sensing in grassland ecosystem monitoring and to provide a scientific reference for ecological remote sensing research.
