“…Thus this explains why TP and TR were delayed on the Straw and Grass treatments. Groundcovers are well known to intercept raindrops and decrease the raindrop energy impact on the soil surface, thus slowing down the generation of ponds and runoff (Keesstra et al, 2019;Yang et al, 2021). Runoff was significantly higher on the Grass treatment than on the Tilled and Straw treatment in the Spring due to higher BD, which ensured faster water rising in the soil, thus making it more susceptible to runoff (Telak et al, 2021).…”

In order to mitigate vineyard degradation, we study different soil management to obtain the most suitable practices. To study the effects of water erosion on vineyards, a rainfall experiment (58 mm h-1 for 30 min) was applied on Anthrosols in humid conditions to assess the impact of treatment (Tilled, Straw and Grass) and season (Spring and Summer). Higher bulk density (BD) and soil water content (SWC) were on the Straw treatment in the Spring period. Also, the Tilled and Grass treatment noticed higher mean weight diameter (MWD) and water-stable aggregates (WSA). In the Summer, BD, SWC and MWD were significantly higher on the Grass treatment. Higher values of time to ponding (TP) and time to runoff (TR) in Spring were recorded on the Grass treatment, Runoff was higher on the Straw treatment. Higher sediment concentration (SC) and soil loss (SL) were noticed during the Tilled treatment. In the Summer period, TP was higher on the Straw treatment, while TR and Runoff were higher on the Straw, SC and SL on the Tilled treatment. This study confirms the positive effects of grass cover and straw mulching as a sustainable agricultural practice in sloped vineyards of north-western Croatia.

“…Lower RIs resulted in weaker impacts of raindrops on the soil. An RI of 80 mm hr −1 was sufficient to induce splash erosion, but it was weak at compacting the soil compared with a larger RI (Berger, Schulze, Rieke–Zapp & Schlunegger, 2010; Yang et al, 2021). Low RIs did not facilitate the bonding of soils and straw; we observed that the influence surface morphology had on surface roughness was significantly greater than that of straw incorporation.…”

The depth and width of rill cutting can be reduced by mixtures, thereby increasing the slope roughness.…”

The hydrodynamic parameters of rainfall runoff are important for those studying hillslope water flow, which in turn affects soil erosion, chemical pollutant migration, and diffusion. Straw incorporation into the cultivated soil layer may affect soil properties, resulting in different hydrodynamic behaviours of hillslope runoff. The objective of this study was to evaluate the influences of straw incorporation, rainfall intensity, and slope gradient on hydraulic parameters, such as the Reynolds number (Re), Froude number (Fr), Darcy‐Weisbach friction factor (f), and hydrodynamic dispersion coefficient (DH). Laboratory experiments were conducted under four straw incorporation rates (SRs: 0, 2, 4, and 8 t ha−1), three rainfall intensities (RIs: 80, 120, and 160 mm hr−1), and three slope gradients (SGs: 10, 15, and 20°) to examine the hydrodynamic characteristics. The results show that the increase in SR significantly reduces the DH. Compared with bare soil slope (0.020 m2 s−1), the mean DH decreased by half (0.011 m2 s−1) at an SR of 2 t ha−1 and approximately three‐quarters (0.005 m2 s−1) at an SR of 8 t ha−1. Both Re and Fr decreased with a rise in the SR; however, the slope roughness increased, which caused a significant increase in frictional force compared to results observed for the bare soil. A rise in RI and SG increased the driving force on the farmland slope. The Re and Fr decreased with RI and SR, while f increased with RI and SG. Therefore, this study elucidates that the incorporation of straw in the soil can alter the hydrodynamic parameters, thus influencing water flow velocity and soil erosion.

“…At present, most scholars have explored the impacts of porous materials on the soil structure (such as the soil porosity, bulk density, water conductivity, etc.) (Humberto, 2017;Dong et al, 2019;Dunkerley, 2021) and revealed its mechanism that the probers materials were how to influence the infiltration process and soil water-holding capacity (Li et al, 2019;Ahmadi et al, 2020;Chen et al, 2020;Yang et al, 2021). Although traditional porous materials increased the infiltration and water-retaining capacity, there were the following defects: blocking soil pores, compacting soil during the application, limiting the improvement range of water-holding capacity (Pu et al, 2019;Zhang F. B. et al, 2019), which would aggravate the soil erosion of farmland in some extreme rainfall events (Werdin et al, 2021;Li et al, 2020).…”

Drought and floods frequently occurred in the Huaibei plain, which was the main factor that restricted agricultural development. We conducted rainfall experiments, which aimed to explore the impacts of porous fiber material (PFM) on the farmland water cycle processes and soil water storage capacity. In this study, we designed two types of rainfall intensities, 4 PFM volumes, 4 growth periods of winter wheat, and a total of 8 experimental groups and 32 rainfall events to evaluate the effects. The result showed that PFM had significantly affected the soil water circulation in the grain-filling period, and the peak flow and runoff decreased maximumly compared with other periods. However, the effect of PFM on surface runoff was slighter in the fallow period, and the peak flow or runoff decreased with the PFM volumes increased (R2 = −0.92, −0.99). In the 100 and 50 mm/h rainfall intensities, PFM decreased the average values of runoff by (55.2–59.6%) and (57.2–90.2%), reduced peak flow by (62.2–68%) and (64.2–86%), and increased the stable infiltration rate by (13.4–14.3%) and (26.6–41.3%), respectively. After the rainfall experiments ended for 1 h, the surface soil water rapidly infiltrated into PFM, which made the water-storage capacity of PFM groups higher than the control groups by 0.2–11% Vol. Subsequently, PFM increased the water-holding capacity by 0.3–2.3% Vol in the 10–70 cm depth from the heading period to the fallow period. It had a positive relationship between the PFM volumes and the average values of soil water content (R2 = 0.8, 0.84). In general, PFM could increase infiltration, reduce runoff, and improve the water-storage capacity to alleviate soil water deficit and the risk of farmland drought and floods. It has an excellent application effect in long-duration rainfall.
