“…17 n. 5, e2814 -Taubaté 2022 The areas of PP and PNHR, due to the arrangement of the groups, did not contribute effectively to the improvement of the edaphic quality within the parameters evaluated, and only the NTS area was closer to the NF. Rosset et al (2014;; Martins et al (2020) and Troian et al (2020) also observed the same behaviors found in this study, with the NF area of vegetation of the Atlantic Forest biome having better edaphic quality in relation to the other managed areas. Rosset et al (2019) observed similarities between the areas of PP and NF.…”

This study quantified the C content of the chemical and physical fractions of SOM in different management systems in an Argisoil of sandy texture. The study was carried out in a reference area of Native Forest (NF), and in three managed areas: Permanent Pasture (PP), No-Tillage System (NTS) and an area of Private Natural Heritage Reserve (PNHR) in the process of natural regeneration. Soil samples were collected in the layers 0.0-0.05, 0.05-0.10 and 0.10-0.20 m. We assessed the soil density (Sd), total organic carbon (TOC) content, chemical fractionation of SOM with determination of the C contents of the fulvic acids (FA), humic acids (HA) and humin (HUM), with subsequent calculations of the HA/FA ratios, AE/HUM, stock (StockC), physical granulometric fractionation and determination of C contents of particulate organic matter (C-POM) and carbon management index (CMI). Higher TOC contents were observed for the NF area. The C-HA and C-HUM contents were higher in the NF and NTS. NF showed higher C-POM levels in all layers evaluated. For the C-MOM, the NTS area was superior to the other managed areas. The managed areas had lower StockPOM values than the NF. The managed areas had lower CMI values in relation to NF. The NTS area showed that, even in crop succession, it contributes to the improvement of the soil organic fraction over the adoption time. On the other hand, the areas of PP and PNHR showed that inadequate management favors the reduction of edaphic quality. Keywords: carbon in soil, carbon management index, chemical fractionation, physical fractionation.

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.

“…The TOC contents of the different areas in the 0-0.05 m layer ranged from 7.28 g kg -1 to 16.42 g kg -1 , with higher content in the NF area (Figure 3). This higher content of TOC in the NF in the surface layer is due to the continuous deposition of plant material from litter (branches, leaves, flowers, fruits, and tree bark) on the soil surface , in addition to lower losses by erosive processes (Barros et al 2013), as well as the absence of anthropic activity in this location, as observed by Rosset et al (2014;2016;, Assunção et al (2019) and Ferreira et al (2020) comparing managed areas and native vegetation of Atlantic Forest in Guaíra, PR, by Ozório et al (2019; in Terra Roxa, PR and Martins et al (2020) and Troian et al (2020) in Iguatemi, MS.…”

This study aimed to evaluate the impact of different land use systems on total organic carbon (TOC) contents and stocks and the daily and total evolution of mineralizable carbon (C-CO2) in a sandy-textured Argissolo Vermelho Amarelo. The study was carried out in Eldorado, MS, in a reference area of Native Forest (NF) and three managed areas: Permanent Pasture (PP), Direct Sowing b(DS), and an area of Private Natural Heritage Reserve (PNHR) in the process of natural regeneration. Soil samples from the 0.0-0.05, 0.05-0.10, and 0.10-0.20 m layers were collected to assess soil density (Sd), TOC contents, with subsequent calculations of the stratification index (SI), carbon stock (StockC), and variation of the total organic carbon stock (∆StockC), in addition to the determination of daily emission and calculation of total C-CO2 accumulation. The NF area had the highest levels and stocks of TOC, reaching 16.42 g kg-1 and 20.90 Mg ha-1, respectively. On the other hand, the PP and PNHR areas had the lowest content and StockC. The areas of PP, DS, PNHR, and NF presented SI values of 1.08, 1.13, 1.32, and 1.61, respectively. The NF area showed higher peaks and a higher total accumulation of C-CO2, inferring the highest biological activity in this area. By multivariate analysis, none of the managed areas was close to the NF in quality. The worst results considering the evaluated attributes were observed in the areas of PP and PNHR due to the stage of degradation of these areas as a result of exploration and land use history.
