“…Thus, the positive effect of no-tillage on the humus state in the studies is explained by modeling of the sod formation process [14,15]. In other studies, the increase in humus content with minimization of the main tillage is explained by a decrease in the intensity of mineralization of crop residues, root residues, and organic fertilizers.…”

Studies, were conducted in a stationary experiment between 1988 and 2018 on dark gray forest heavy loam soil in Scientific Research Institute of Agriculture for Northern Trans-Ural Region - Branch of Federal State Institutions Federal Research Centre Tyumen Scientific Centre of Siberian Branch of the Russian Academy of Sciences. The aim of the study is to determine the effect of long-term (30 years) impact of different systems of basic cultivation of dark gray forest soils in the cultivation of grain crops on the humus content. Observations were made according to generally accepted methods during 6 rotations of grain and fallow crop rotation: bare fallow, winter rye, spring wheat, spring vetch, spring barley, unfolded in time and space. The impact of the combined system of tillage with alternation of plowing and no-tillage at 20-22 cm during 6 rotations of a 5-pole grain and steam crop rotation (30 years), increased the humus content in the 0-40 cm layer of dark gray forest soil compared with the initial content by 0.42%. The systems of main tillage - differentiated, without sowing, and mouldboard provided in general a relatively favorable dynamics of the humus state of the soil. The content of humus in the 0-40 cm layer of soil by differentiated and unswept systems during the study period remained close to the initial condition. По отвальной системе содержание гумуса снижалось на 0,22% или в среднем 0,37т/га в год. The greatest loss of humus in the 0-40 cm layer of soil by 0.80% in relation to the initial was the impact of surface treatment with annual discing BDT-2,5 (heavy disc harrows) on 10-12 cm or an average annual loss of 1.33 t / ha.

“…Besides, microbial degradation may contribute greatly to the OM content increment under various agricultural practices. Significant differences in soil OM content under crop rotation and different tillage methods may be associated with management‐induced OM stripping at the soil surface (Man et al, 2021). However, tillage areas may have lower OM than no‐tillage areas in other soil types (Gómez‐Paccard et al, 2015).…”

Agricultural activities have raised increasing concern regarding their effects on soil properties and shear strength, which are related to root growth, crop yield and engineering stability. We collected undisturbed soil samples (0-15 cm) from a No-Reclaimed (NR) system, a Short-term Reclaimed (SR) system for less than 7 years, and a Long-term Reclaimed (LR) system for more than 30 years, in coastal

“…Moreover, no‐tillage also significantly improved soil aggregate stability (Fernández et al, 2017; Tourn et al, 2019). Therefore, implementing no‐tillage or other conservation tillage measures in black soil areas, with few conservation tillage practices, may be a feasible measure to slow the decrease in the mSOM and the bulk SOM C content (Hao et al, 2020; Man et al, 2021; Wulanningtyas et al, 2021).…”

Accumulation of SOM fractions to croplands and plantations converted from cropland with black soil

et al. 2022

View full text Add to dashboard Cite

Soil organic matter (SOM) decreases after the conversion of native grasslands to croplands and increases after the conversion of croplands to plantations. However, the reasons for loss and/or accumulation of SOM fractions remain unclear. Hence, we investigated SOM fraction quantity and quality of soils from cropland (CL), a plantation (PL) converted from cropland, and native grassland (NG) all converted from the black soil (Mollisols) region of China. Results showed that: (1) across all sites, coarse
