“…We have used the SOC sequestration rate of 37 years old hedgerows to upscale our results over a 40 years period, as beyond this we are likely to overestimate their ability to sequester carbon. This sequestration rate may not be representative of all hedgerows, as the rate of SOC storage is influenced by external factors of soil type and climatic conditions, as well as hedgerow structure and species composition ( Thiel et al, 2015 ; Ford et al, 2021 ). Rainfall water accumulation and discharge, for example, affect erosion rates and both high and low soil moisture affect soil SOC storage by reducing microbial activity ( Frank et al, 2015 ).…”

“…Accurate rates of CO 2 sequestration by soil beneath hedgerows are limited by lack of information regarding SOC stocks beneath managed hedgerows and how factors such as soil depth and hedgerow age may affect them ( Wolton et al, 2014 ), as well as how SOC stock beneath hedgerows may compare to those in adjacent agricultural fields ( Ford et al, 2021 ; Viaud and Kunnemann, 2021 ). The SOC stock beneath hedgerows will depend on a number of factors, such as the maturation stage of the hedgerow, previous land use, the soil physical and chemical properties at the time of planting, and the depth of sampling ( Laganière et al, 2010 ).…”

“…The effect of grazing on the carbon budget of grassland ecosystems has mainly been evaluated through experimental observations, remote sensing, and model simulation (Lin et al, 2017;Jia et al, 2018;Ford et al, 2021;Li et al, 2021). Experimental observations are often too time-consuming and labor-intensive to be conducted over large areas, especially when there is high spatial heterogeneity in climate, terrain, and management regimes.…”

Spatiotemporal Dynamics of the Carbon Budget and the Response to Grazing in Qinghai Grasslands

Estimating the grassland carbon budget is critically important for ensuring that grassland resources are used sustainably. However, the spatiotemporal dynamics of the carbon budget and the response to grazing have not yet been characterized in Qinghai grasslands. Here, we estimated the gross primary productivity (GPP) and net ecosystem exchange (NEE) in Qinghai grasslands using the improved Biome-BGCMuSo model to characterize the spatiotemporal dynamics of the carbon budget and the response to grazing in this region from 1979 to 2018. The GPP of Qinghai grasslands fluctuated during the study period, with an average annual value of 118.78 gC/m2. The NEE of Qinghai grasslands fluctuated from 1979 to 2018, with an average value of −5.16 gC/m2. After 2,000, GPP increased, and NEE decreased in a fluctuating manner. There were clear regional differences in GPP and NEE. GPP was low in most areas of Qinghai, and GPP was high in eastern and southern Qinghai. The southern, southeastern, and northeastern parts of Qinghai were mainly carbon sinks, and the northwestern part of Qinghai and the region between the southeastern and northeastern parts of Qinghai were mainly carbon sources. Grazing generally decreased GPP and increased NEE in Qinghai grasslands from 1979 to 2018. There was spatial heterogeneity in the effect of grazing on GPP and NEE. Under grazing, GPP and NEE were significantly decreased mainly in eastern Qinghai, and GPP and NEE were significantly increased mainly in southern and eastern Qinghai. NEE was most affected by grazing in eastern Qinghai. The results of this study aid our understanding of the mechanism driving variation in the grassland carbon budget and provide new data that could be used to support local grassland management.

“…Four research articles analyzed soil carbon emissions under different precipitation regimes (Lai et al 2016, one study evaluated both soil carbon sequestration and emissions under different soil moisture conditions (Singh et al 2021), one study assessed SOC under the effect of different irrigation inputs during a drought event in a semi-arid climate (Bhandari et al 2022), and one study evaluated the influence of soil type and soil water drainage capacity on soil carbon emissions under drought in a maritime climate (Ford et al 2021). Regarding the effects of precipitation, two studies evaluated the effects of drought on cropland and a jujube orchard, compared with abandoned grassland and shrubland, in a semi-arid continental climate (Sun et al 2018(Sun et al , 2021.…”

Drought is a natural hazard occurring with increasing frequency due to climate change. Drought events reduce soil water content and also soil organic carbon (SOC) content, with negative impacts on crop development and food security. This study investigates the impact of drought on SOC dynamics in agricultural systems and the influence of water availability and farm management practices in these impacts. The manuscript is a systematic review, based on Scopus database for scoping the literature on the topic. A total of 283 records were retrieved, but only 16 papers were relevant for the review. The main findings are: 1) water plays a key role in regulating SOC mineralization, necessitating further research on water management to mitigate carbon losses during drought; 2) different agricultural systems can have differing impacts on SOC under drought conditions (e.g., pastures are more resilient than arable systems); and 3) SOC loss generally occurs after a drought event, regardless of farm management regime. Best management practices, such as cover cropping and soil amendment, can minimize SOC losses, but further research is required to optimize these practices in counteracting the effect of drought. A better understanding of the effects of drought on SOC dynamics, and of short-term and long-term ways to mitigate these effects, is important to ensure soil health and crop productivity.
