“…The contribution of the root system to total plant carbon (C) storage can range from 9 to 26%, and total C storage in the vineyard can range from 5.7 to 7.2 t C/(ha/year) (Brunori et al 2016). Thus, vineyard soils and root systems can positively contribute to the mitigation strategies to manage climate change by increasing soil carbon storage (Funes et al 2019).…”

Viticulture is facing emerging challenges not only because of the effect of climate change on yield and composition of grapes, but also of a social demand for environmental‐friendly agricultural management. Adaptation to these challenges is essential to guarantee the sustainability of viticulture. The aim of this review is to present adaptation possibilities from the soil‐hidden, and often disregarded, part of the grapevine, the roots. The complexity of soil–root interactions makes necessary a comprehensive approach taking into account physiology, pathology and genetics, in order to outline strategies to improve viticulture adaptation to current and future threats. Rootstocks are the link between soil and scion in grafted crops, and they have played an essential role in viticulture since the introduction of phylloxera into Europe at the end of the 19th century. This review outlines current and future challenges that are threatening the sustainability of the wine sector and the relevant role that rootstocks can play to face these threats. We describe how rootstocks along with soil management can be exploited as an essential tool to deal with the effects of climate change and of emerging soil‐borne pests and pathogens. Moreover, we discuss the possibilities and limitations of diverse genetic strategies for rootstock breeding.

“…In general, the mean SOC stocks decreased by 35−47% from 0-20 cm to 20-40 cm and by 25−33% from 20-40 cm to 40−60 cm. Other studies, such as Conant et al [28] in the southeastern United States, Li et al [43] in southwestern China, Tsozué et al [44] in central Africa, Funes et al [33] in north-eastern Spain, Chen [45] in central Taiwan, and Parras-Alcántara et al [46] in southern Spain, have also reported a decrease in SOC with depth.…”

“…For example, mean SOC stocks were 1.7 ± 0.18 to 2.5 ± 0.24 kg/m 2 at 0−20 cm, 1.1 ± 0.08 to 1.3 ± 0.18 kg/m 2 at 20−40 cm, and 0.8 ± 0.14 to 0.9 ± 0.15 kg/m 2 at 40−60 cm. The range of SOC stocks in the three fields are comparable to other croplands studies, such as those conducted in Ohio, United States (mean: 0.41-2.24 kg/m 2 ) [40] and southern Germany (mean: 2.0-2.9 kg/m 2 ) [41], but lower than croplands in western Minnesota, United States (mean: 3.27 kg/m 2 ) [42], north-eastern Spain (mean: 3.5-14.7 kg/m 2 ) [33] and western Australia (mean: 3.1 kg/m 2 ) [6].

“…Accurate bulk density values are critical to determining the change in SOC stocks. As we have limited values for field bulk density and these values are similar to the SSURGO database, the bulk density values in three fields at three depths from the SSURGO database were used to calculate total organic C (hereafter referred to as SOC) stocks based on the fixed depth intervals for each field site, as shown in the following equations [33].

Assessing Soil Organic Carbon in Soils to Enhance and Track Future Carbon Stocks

et al. 2020

Soils represent the largest terrestrial sink of carbon (C) on Earth, yet the quantification of the amount of soil organic carbon (SOC) is challenging due to the spatial variability inherent in agricultural soils. Our objective was to use a grid sampling approach to assess the magnitude of SOC variability and determine the current SOC stocks in three typical agricultural fields in Maryland, United States. A selected area in each field (4000 m2) was divided into eight grids (20 m × 25 m) for soil sample collection at three fixed depth intervals (0–20 cm, 20–40 cm, and 40–60 cm). Soil pH in all fields was significantly (p < 0.05) greater in the surface soil layer (6.2–6.4) than lower soil layers (4.7–5.9). The mean SOC stocks in the surface layers (0–20 cm: 1.7–2.5 kg/m2) were 47% to 53% of the total SOC stocks at 0–60 cm depth, and were significantly greater than sub-surface layers (20–40 cm: 0.9–1.3 kg/m2; 40–60 cm: 0.8–0.9 kg/m2). Carbon to nitrogen (C/N) ratio and stable C isotopic composition (δ13C) were used to understand the characteristics of SOC in three fields. The C/N ratio was positively corelated (r > 0.96) with SOC stocks, which were lower in sub-surface than surface layers. Differences in C/N ratios and δ13C signatures were observed among the three fields. The calculated values of SOC stocks at 0–60 cm depth ranged from 37 to 47 Mg/ha and were not significantly different in three fields likely due to the similar parent material, soil types, climate, and a short history of changes in management practices. A small variability (~10% coefficient of variation) in SOC stocks across eight sampling grids in each field suggests that re-sampling these grids in the future can lead to accurately determining and tracking changes in SOC stocks.

“…Based on evidences from Germany, Vos et al [22] demonstrated that agronomic management can increase the carbon sink capacity of soil surface. Funes et al [23] discovered that the organic carbon stock of surface soil is mainly influenced by climate, soil texture, and agricultural variables, while that of bottom soil is mainly affected by soil texture, clay content, soil type and bedrock depth. Hertwich and Peters [24] calculated the carbon footprint of Luxemburg and 72 other countries, using the multi-regional input-output (MIRO) model.…”

To promote sustainable development of agriculture, it is critical to reduce carbon sources and increase carbon sinks in farmland ecosystem by rationalizing the measures of agricultural management. This calls for scientific evaluation of net carbon sink (NCS) and its spatiotemporal evolution of farmland vegetation in a region. Taking 38 districts/counties of Chongqing, China as objects, this paper estimates the farmland vegetation NCS of Chongqing, based on statistics of crop yields and farmland inputs in 2000-2017. Then, geographical techniques were employed to analyze the features, regional difference and spatial evolution of NCS in Chongqing and its districts/counties. The main results are as follows: (1) From 2000 to 2017, the NCS and NCS strength (NCSS) of farmland vegetation in Chongqing both increased with fluctuations. The carbon sink, carbon emissions and carbon absorption increased across the board. The evolution of farmland vegetation can be divided into a wavy decline phase from 2000 to 2006, and a gradual increase phase from 2006 to 2017. (2) The source/sink structure of farmland vegetation in Chongqing remained stable in 2000-2017. The main sources are pesticide and tillage, and the main sinks are corn, rice, vegetables and oil crops. (3) In term of space, the farmland vegetation NCS and its center of gravity concentrated in the west zone and northeast zone. In general, the farmland vegetation of Chongqing boasts a strong carbon sink function; the west zone and northeast zone have the highest farmland vegetation NCSs; the west zone is the demonstration region of NCSS improvement.
