“…However, as pointed out by several studies when grasses are mixed with trees under an SPS management, an increase in above and belowground biomass of the system is expected, resulting in higher organic residues C inputs to the soils, thus enhancing the SOC stocks (Sarto, Borges, Sarto, Rice, & Rosolem, 2020b; Webster, Gaudin, Pulleman, Siles, & Fonte, 2019), as we observed in our study (0.35 Mg C ha −1 yr −1 ). Increments in SOC stocks induced by SPS implementation were also observed in other countries, such as Brazil (Lira et al, 2020; Sarto, Borges, Sarto, Rice, & Rosolem, 2020b), Nicaragua (Hoosbeek et al, 2018), and England (Upson, Burgess, & Morison, 2016).…”

Restoring soil carbon and chemical properties through silvopastoral adoption in the Colombian Amazon region

Silvopastoral systems (SPS) have been widely implemented in the Colombian Amazon region to improve pastures involving a greater diversity of species, soil tillage, fertilization, and higher stocking rate, which can induce changes in soil properties and functions. This study aimed to evaluate soil chemical properties and carbon sequestration changes due to the transition from traditional pastures to silvopastoral systems. The study was conducted in the Colombian Amazon region, specifically in La Montañita and El Doncello Counties, in Caquetá, the second most important hotspot of deforestation in the entire Amazon basin. In each study site, we established a chronosequence consisting of three areas following the typical land‐use change at the region: (i) native vegetation, (ii) traditional pasture, and (iii) silvopastoral system. We found that agricultural practices involving liming and tillage, performed under the silvopastoral management, contributed to reducing soil active acidity and exchangeable acidity with soil pH increasing from 3.8 to 4.3 and H++Al3+ decreasing from 5.8 to 2.3 cmolc kg−1. These alterations favored increases in Ca2+ and Mg2+ contents mainly, increasing the base saturation from 17% in traditional pastures to 55% under silvopastoral systems. The synergic effect of the mix of grasses and trees under silvopastoral management improved soil micronutrient contents and modified soil C stocks in 20–30 cm layer. A rate of soil C accretion of 0.26 Mg ha−1 yr−1 for the 0–30 cm detected in silvopastoral systems suggests that its implementation could be a promising tool for C sequestration in tropical regions, capable of restoring soil functioning of degraded areas.

“…Systems managed with pastures are important in maintaining soil quality, given the extension of these cultivated areas across the planet (Salton et al, 2008;Santos et al, 2019), especially pastures with adequate management, which present an increase in SOM in surface and subsurface layers due to root decomposition (Coonan et al, 2019;Malcolm et al, 2019). On the other hand, pastures undergoing degradation stages, with low biomass production and soil cover and under the beginning of the emergence of erosive processes, negatively influence soil quality, compromising soil C quality and quantity (Segnini et al, 2019;Zago et al, 2019;Webster et al, 2019).…”

This study aimed to assess the soil density (Sd) and the total organic carbon contents and stocks in different management systems and implementation times in the municipality of Iguatemi, MS, Brazil. A completely randomized design with four replications was applied to four areas: conventional tillage (CT), reformed pasture (RP), and degraded pasture (DP), in addition to a native forest (NF) area with no anthropic action. Disturbed and undisturbed soil samples were collected at depths of 0–0.05, 0.05–0.1, and 0.1–0.2 m. The determination of Sd and total organic carbon content (TOC) allowed calculating the carbon stock (Cstock), the stratification index (SI), and the carbon stock variation (ΔCstock), with subsequent multivariate analysis. The NF area presented the highest TOC contents at all depths compared to the managed areas, with a value of 17.45 g kg−1 at a depth of 0–0.05 m. The RP and NF areas showed similar SI, which was higher in PD, with a value of 2.54. Except for RP, the other managed areas showed a negative ΔCstock in the soil profile relative to the NF area. The RP and NF areas promoted the maintenance of TOC in the soil, while DP and CT compromised the edaphic quality.

“…For a long time, due to the unreasonable development and utilization of resources, a variety of mining environmental geological problems have been raised (Chen et al, 2019). According to the statistical analysis of national geological environmental survey data, environmental geological problems caused by mining activities mainly include geological disasters such as landslides, collapses, mudslides, ground subsidence, ground subsidence, and ground fissures, occupation and destruction of land resources, destruction of water resources, land desertification and soil erosion (Webster et al, 2019;Cui & Wang, 2019). The specific content is shown in Table 1.…”

Aiming at the destruction of the ecological environment of the comprehensive geological structure, the traditional restoration countermeasures have the problems of high input cost and low economic benefits. For this reason, the ecological environment destruction process and restoration countermeasures of the comprehensive geological structure were proposed. The common geological structure characteristics and the impact of activities on the ecological environment in the mining area were analyzed. Based on the analysis results, an evaluation system for the degree of damage to the ecological environment by mining activities was constructed. According to the expert scoring method, a rating standard was developed to measure the degree of damage to the ecological environment. Depending on the degree of damage, appropriate recovery measures were formulated. The experimental results show that compared with the traditional restoration countermeasures, considering the destruction of the ecological environment during the mining process of comprehensive geological structures, the proposed restoration countermeasures have the advantages of low cost and high economic benefits.
