“…We found strong evidence to support the hypothesis that plant roots bind soil particles together, making the soil less susceptible to erosion. Roots contribute to this by: increasing soil cohesion/root reinforcement (Burylo et al 2011a;De Baets et al 2009;Farhadi et al 2018;Hamidifar et al 2018;Li et al 2014;Zegeye et al 2018), reducing sediment loss/erodibility (Chau and Chu 2017;Zhang et al 2017), increasing the shear strength of the soil (Chen et al 2019), forming a mesh that bind soil particles (Chomczyńska et al 2016), reducing the relative soil detachment rate (De Baets et al 2007;Farhadi et al 2018;Li et al 2014;Vannoppen et al 2016), and increasing aggregate stability (Hudek et al 2017).…”

Background Soil erosion adversely impacts natural and human environments globally. Vegetation is a sustainable approach used in mitigating erosion. Although using vegetation to reduce erosion is a widely accepted concept, how the different traits of vegetation mitigate the different mechanisms of erosion are not well understood. Methods We developed 12 hypotheses on how traits of vegetation (roots, leaves, and stems) act to reduce erosion through different mechanisms (binding soil particles, promoting suspended sediment deposition and reducing the energy of waves, runoff, and wind). We then conducted a rapid evidence assessment of the scientific literature using the Eco-Evidence method. Results We found strong evidence to support our overarching hypothesis – an increase in plant abundance reduces erosion. We also found support for the specific hypotheses that plant roots bind soil particles and that greater plant stem density and leaf area reduce surface run-off and promote sediment deposition. There was insufficient evidence to support the hypotheses that plant roots promote sediment deposition or reduce wave energy, or that stem density and leaf area reduce wave or wind energy. None of our hypotheses were rejected. Conclusion Species with high root and stem densities and greater leaf area will be most effective in mitigating erosion. Our review highlights that there is insufficient evidence regarding some potentially important mechanisms between vegetation and erosion, making these prospective areas for further research. These results should be considered by environmental engineers in designing schemes to reduce erosion and ecologists who are concerned about preserving vegetation in erosion-prone environments.

Soil erosion adversely impacts natural and human environments globally. Vegetation is often used as a sustainable approach to mitigate erosion. Although using vegetation to reduce erosion is a widely accepted concept, how different plant traits mitigate different mechanisms of erosion, and the generality of these mechanisms has not been well demonstrated. We developed ten hypotheses on how different plant traits (roots, leaves, and stems) act to reduce erosion through different mechanisms (binding soil particles, promoting suspended sediment deposition and reducing the energy of waves, runoff, and wind). We then conducted a rapid evidence assessment of the scientific literature using the Eco Evidence method. We found strong evidence to support our overarching hypothesis—an increase in plant abundance reduces erosion. We also found support for the specific hypotheses that plant roots bind soil particles and that greater plant stem density and leaf area reduce surface run-off and promote sediment deposition. There was insufficient evidence to support the hypotheses that an increase in stem density or leaf area reduces wave or wind energy. None of our hypotheses were rejected. Species with higher root and stem densities and greater leaf area will be the most effective in mitigating erosion. Our review highlights that there is insufficient evidence regarding some potentially important mechanisms between vegetation and erosion, making these prospective areas for further research. Our results have the potential to aid environmental engineers when designing schemes to reduce erosion and ecologists and managers who are concerned about the conservation and restoration of erosion-prone environments.

The objectives of the experiment were to: (1) evaluate the effects of ground contact pressures of 0.051, 0.103 and 0.154 MPa on physical properties of sandy loam Eutric Cambisol and clayey loam Vertic Cambisol, and (2) assess the effects of winter wheat roots on the recovery of physical properties of the compacted soils. A 49day pot experiment included treatments with winter wheat (Triticum aestivum L.) growing until the BBCH 10 growth stage. The ground contact pressures were created by a hand-operated hydraulic compressor equipped with a manometer. As a reference, pots with uncompacted soils without plants were also included in the experiment. At the end of the experiment, bulk density, penetration resistance, total amount of water-stable aggregates (WSA), their size fractions and weight of dry roots in the whole 0-15 cm layers of both soils were determined. The ground contact pressures resulted in significantly higher mean values of bulk density in the 0-15 cm layers for both soils without plants compared to the uncompacted soils. Winter wheat roots contributed to a decrease in the mean values of bulk density of the clayey loam by 1.4, 3.8 and 4.9 %, but caused the increase in those of the sandy loam by 6.2, 5.1 and 1.8 % at the ground contact pressures of 0.051, 0.103 and 0.154 MPa, respectively. The ground contact pressures caused mostly a significant increase in the mean penetration resistance of the 0-5 cm layer in the clayey loam and sandy loam without plants compared to the uncompacted soils. The roots did not contribute to any significant change in the mean magnitudes of penetration resistance of both soils at the three studied levels of compaction. Total amount of WSA of the two soils significantly decreased after the compaction by all the applied ground contact pressures. Winter wheat roots contributed mainly to a partial recovery of the total amount of WSA in both compacted soils compared to those of the uncompacted soils.
