“…Concerning SOC, Santos et al (2019) assessed the effect of land-use changes in SOC stocks (TCS) and microbial biomass carbon (MBC) in semi-arid Brazilian, and found that the conversion of forest (Caatinga) into successional areas can decrease by up to 44 % TCS and 68 % MBC, affecting, thus, the SR and corroborating with our results. The SOC values in both land-uses (8.44 and 18.13 g kg -1 in degraded pasture and Caatinga, respectively) are within the range reported by other authors (Medeiros et al, 2017;Santana et al, 2019) in the semi-arid region of Brazil.…”

“…To fully utilize the carbon sink function of farmland vegetation, the above zones must attach importance to ecological agriculture, protect farmland and modernize agriculture in future [16,17]. In the west zone, modern urban agriculture is developing rapidly, as evidenced by the growing investment in agriculture.…”

“…But the latter is arousing a growing interest in the academic circle. The relevant studies either focus on macro levels like country level [13,14] and provincial level, or target micro issues like soil carbon [15,16]. For example, Kay et al [17] held that agroforestry creates carbon sinks while enhancing the environment in agricultural landscapes.…”

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.

“…Thus, changes in vegetation covers use, depending on the management applied, can reduce or increase the C stocks in humic fractions (Santana et al, 2019). One way to mitigate C emission in atmosphere is preservation of native forests and reforestation, measures like these remove large amounts of CO 2 from the atmosphere, through photosynthesis, and store C in biomass and soil (Soleimani et al, 2019).…”

Carbon Dynamics in Humic Fractions of Soil Organic Matter Under Different Vegetation Cover in Southern Tocantins

et al. 2021

Soil organic matter has great importance in chemical, physical and biological processes in soil-plant system. This study aimed to evaluate changes in carbon humic fractions of soil organic matter under different vegetation coverings in Cerrado in Tocantins, Brazil. The work was developed in Eucalyptus sp., Pasture, Agriculture and Cerrado sensu stricto areas. Soil samples were collected in dry period, October, 2018, in trenches 70 x 70 cm at depths 0-10, 10-20, 20-30, 30-40 and 40-50 cm, with six replications. The vegetation cover in Eucalyptus sp. area showed higher levels of total carbon in soil humic fraction. Respectively fulvic acid, humic acid and humin in Eucalyptus sp. area had stocks of 22.09; 2.71 and 20.01% higher than native forest, 32.04; 2.57 and 35.59% higher than pasture and 10.59; 19.19 and 7.61% higher than the agriculture area. Among the different areas evaluated, the soil of Eucalyptus sp. has great potential to increase carbon storage in soil humic fractions.
