“…Studies revealed that the runoff coefficients of natural slopes are 2.79 to 11.50 times higher than those of slopes after land preparations (Darvishan, Homayounfar, & Sadeghi, 2016). Additionally, land preparations improve soil water storage by capturing and harvesting substantial rainwater.…”

In the dryland and degraded regions, soil moisture is the primary factor determining ecological restoration. Proper land preparations and vegetation restoration can improve soil moisture and benefit land restoration. Identifying their effects on soil moisture is thus essential for developing suitable management strategies. In this study, four typical land preparation techniques (level ditches, fish‐scale pits, zig terraces, and level benches) and non‐native vegetation types (Prunus armeniaca, Platycladus orientalis, Pinus tabulaeformis, and Caragana microphylla) were planted on a semiarid loess hilly catchment, China. Soil moisture was monitored by a time‐domain reflectometer, and its spatial–temporal variations were analyzed during the 2014–2015 growing seasons. The following results were captured. (a) Soil moisture was highest for the combination of P. orientalis and fish‐scale pits (P. orientalis/fish‐scale pits, 10.37%), followed by P. armeniaca/level ditches (10.23%), P. orientalis/zig terraces (9.67%), C. microphylla/level benches (8.62%), P. tabulaeformis/fish‐scale pits (8.05%), and P. tabulaeformis/zig terraces (7.72%). (b) Fish‐scale pits offered a better rainwater‐harvesting capacity during the rainy months, whereas zig terraces had a higher water retention capacity under extremely dry conditions (as indicated by the temporal soil moisture variation and soil water retention curves). (c) P. tabulaeformis consumed more water than other vegetation types (26.7% lower than that of P. orientalis). (d) Soil moisture in shallower layers (0–80 cm) was more affected by land preparations and was more effected by vegetation types in deeper soil layers (80–180 cm). We thus suggest that fish‐scale pits may be a better choice in wetter regions whereas zig terraces and P. orientalis are more suitable in the driest parts of the Loess Plateau to restore the fragile ecosystems.

“…Soil erosion is one of the most widespread and a major environmental threat which decreases agricultural productivity and affects water quality (Artemyeva et al, 2021;Kavian et al, 2018;Kavian et al, 2017;Khaledi Darvishan et al, 2016;Mohammadi and Kavian, 2015;Spalevic et al, 2013;Nearing et al, 2005). Water erosion has drastically affected the productive capacity of soils, especially in tropical regions, due to the large volume of rainfall (Panachuki et al, 2006;Santos et al, 2010).…”

Water erosion has radically affected the productive capacity of soils, especially in regions with a tropical climate, causing environmental and social damage, such as reduced agricultural productivity and siltation of water bodies. The objective of this research was to estimate soil losses with using the IntErO model -Erosion Potential Method in the River Machado Watershed (MRW), South Minas Gerais State (Brazil), with the idea to identify areas of increased soil losses due to water erosion, contributing with the research activities to the environmental planning in order to prevent land degradation. The Machado River basin was selected as study area because it is an important Sustainable Use Conservation Unit in Minas Gerais, which has abundant water resources, rich biodiversity, and intensive agricultural production. The estimated soil losses for the year 2020 were calculated, using the IntErO model -Erosion Potential Method, in a Geographic Information System (GIS) environment. The MRW presented an average soil loss of 18.2 Mg ha -1 yr -1 , and a total of about 2 million tons per year. In about 85% of the watershed, soil losses were greater than the tolerable limits, what leads to the conclusion that there is a need to adopt a comprehensive soil conservation management plan to reduce water erosion. The highest average soil losses occurred in areas of exposed soil as well as sporadic agricultural and pasture, and are concentrated in the southern sector of the studied area. The results obtained can support the environmental planning aimed at the conservationist use of the soil in the MRW.

“…La erodabilidad se ref iere a la susceptibilidad del suelo a la erosión por el agua o el viento, y este se identif ica como un controlador secundario en la intensidad de los factores ambientales (USDA-ARS, 1997;Shabani et al, 2014). La susceptibilidad del suelo a la erosión hídrica (SEH) es determinada primordialmente por el potencial erosivo de la lluvia, por la inclinación del terreno o grado de pendiente, por la superf icie y posición de captación o (área) de impacto de la lluvia, por las cubiertas en su superf icie (FAO and ITPS, 2015) y por la acción antrópica (Wang et al, 2015;Darvishan et al, 2016).…”

Erosion estimates for black soils in Mexico based on the Universal Soil Loss Equation (USLE) present discrepancies due to generalizations that lead to errors in permissible limits, with the erodibility factor or K factor (FK) being the most sensitive. The objective of the present investigation was to obtain a reasonable FK range for a Phaeozem (PH) from central Mexico by contrasting two equations based on the USLE. Samples were randomly obtained at three sites (P1, P2, P3) of a four-hectare area. The percentage of organic matter, textural class, soil structure, and profile permeability were determined. The results reveal differences between the estimated FK (FKe) and reference FK (FKr), whose values were +0.015, +0.028, and +0.029 for P1, P2, and P3, respectively. The differences represent underestimations that are up to 1.7 times greater in magnitude for FKr with respect to FKe. The statistical analysis rejects the null hypothesis (H0) that the means of each site evaluated are the same (P1 = P2 = P3). Although the variances between the factors of erodibility obtained using the equation specific to the Mollisols in Yunnan Province, China, and the reference nomography developed primarily in United States are significantly different (α ≥ 0.01), a combination of both could provide a range of maximums and minimums in the FK estimates and would yield better results than with the use of default values that tend to underestimate erosion rates.
