“…In the 40‐ to 60‐cm soil layer, a higher SOC value was found in ST compared with other tillage methods. These results are consistent with the findings of many scholars and indicate that conservation tillage is good for soil carbon accumulation (Marinho, Pereira, Vidal Vazquez, Lado, & Paz Gonzalez, ; Melero et al, ).…”

“…We also found an increasing trend in stratification ratios with BT and ST, which means that SOC accumulated on the surface, but in ST, the opposite trend was observed. The same result has also been found in other reports (Chen et al, ; Lopez‐Fando & Pardo, ; Marinho et al, ). According to Chabbi and Rumpel (), SOC accumulations on the surface are common because of the lower transport rate but surface SOC is prone to mineralization (Murphy et al, ), and the immobilization of organic carbon in deep soil is conducive to the stable accumulation of soil carbon.…”

Soil organic carbon (SOC) is a core indicator of soil quality. A proper tillage system can improve SOC accumulation and benefit land restoration. This improvement is especially significant in loess soil, which is undergoing serious degradation in China. In this study, we chose a field that was used for crop production and used a traditional moldboard plow with crop residue removal (CT) for over 10 years. We then carried out a long-term field experiment (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015) and changed the tillage system from a moldboard plow with crop residue removal to either a moldboard plow with buried straw system (BT), a no-tillage with straw mulch system (NT), or a subsoiling with straw mulch system (ST) to evaluate the effect of tillage system change and the effects of tillage systems on SOC storage. Tillage system change influenced SOC content, NT, ST, and BT showed higher values of SOC content and increased 8.34, 7.83, and 1.64 Mg·C·ha −1 , respectively, compared with CT. Among the 3 changed tillage systems, NT and ST showed a 12.5% and 11.6% increase in SOC content then BT, respectively. Tillage system change influenced SOC stratification ratio values, with higher value observed in BT and NT compared CT but ST. Therefore, in loess soil, changing tillage system can significantly improve SOC storage and change profile distribution. The NT and ST treatments showed a more marked SOC increase, but the increase value in stratification ratio with NT still needs attention, and our results is meaningful for soil quality improvement and land restoration.

“…Existing studies show that indices such as F, F silt , F sand , D 0 , D 1 , D 2 and D 1 /D 0 highly correlate with soil organic matter, and these measures can potentially be used to reflect soil quality (Marinho et al, 2017;Wang et al, 2007;Zaffar and Lu, 2015;Zhang et al, 2012aZhang et al, , 2012b. These indices also differed at different slope positions and soil depths in this study.…”

In the context of global climate change as well as local climate warming and drying on the Loess Plateau of China, understanding the relationship between soil particle size and soil water distribution during years of atypical precipitation is important. In this study, fractal geometry theory is used to describe the mechanical composition and texture of soils to improve our understanding of hydropedology and ecohydrology in the critical zone on the Loess Plateau. One grassland slope and two shrubland slopes were selected in the hilly and gully region of the Loess Plateau, and soils were sampled along hillslope transects at depths of 0-500 cm. Fractal theory and redundancy analysis (RDA) were used to identify relationships between the fractal dimension of soil particle-size distributions and the corresponding van Genuchten parameters for the soil-water-characteristic curves. The oven-drying method was used to measure soil water content, and the high-speed centrifugation method was used to generate soil-water-characteristic curves. The results show that (1) the soil water that can be used by Caragana korshinskii during a drought year is distributed below 2 m from the surface, whereas the soil water that can be used by grass is below 1.2 m; (2) Caragana korshinskii promotes the conservation of fine soil particles more than does natural restored grass, and the soil particle-size distribution fractal dimension changes with depth and position; and (3) soil hydraulic properties correlate strongly with soil pedological properties such as bulk density and the soil particle-size distribution fractal dimension. These results provide a case study of the relationships among soil distributions, hydrologic and geomorphic processes for vegetation restoration in drylands with a thick vadose zone. More studies on soil property changes are needed to provide case studies and empirical support for ecological restoration in the Loess Plateau of China.

“…The maximum SOC stock was 262 Mg ha -1 . Several papers confirm, that under variable conditions, the highest organic carbon stocks occur in the topsoil layer, down to the depth of 30 cm (Marinho et al 2017;Börjesson et al 2018). De Vos et al (2015) estimated its total stocks at 3.50-3.94 Gt C in forest floors and 21.4-22.7 Gt C in mineral and peat soils down to 1 m in European forests.…”

The objective of the study is the presentation of the chemical properties of forest chernozems and the features of forest habitats developed on chernozems in south-eastern Poland. The assessment of the trophic status of chernozems was presented based on the Trophic Soil Index (SIG). Moreover, the paper presents the diversity of forest vegetation on chernozems. The research covered 15 plots from the habitat inventory performed for the Mircze and Strzelce Forest Districts (SE Poland). Habitat conditions were characterised on the research plots, with particular consideration of the soil and vegetation. The analysed soils were featured by the presence of thick humus horizons and the occurrence of calcium carbonate. High SIG values confirm the eutrophic status of the analysed soils. In general, fresh and wet habitats of broadleaved forests (Lśw and Lw), as well as fresh habitats of broadleaved upland forest (Lwyżśw) develop on chernozems in Poland. They are associated with multi-species broadleaved tree stands. The conducted research indicates that, in current environmental conditions, the potential plant community is oak-hornbeam forest with predominance of oak, hornbeam, and abundant admixtures of other broadleaved species. High trophic status of the analysed chernozems is confirmed by high bonitation of tree stands and richness of forest floor vegetation.
