“…Forest cover plays a very important role in the reduction of soil erosion intensity with multiple favourable effects [19,61,62]. Therefore, it has been widely considered as the most effective biotechnical measure [9,63].…”

Abstract:The aim of this research was to analyse the changes in the soil erosion intensity caused by erosion control works (ECW) in Grdelica Gorge (The South Morava River) in the period between 1953 and 2016. For the purpose of quantifying the erosion intensity changes, the erosion potential model (EPM) was used to calculate the annual gross erosion (W), sediment transport (G), and erosion coefficient (Z) in the study area. As a result of the performed technical and biotechnical erosion control works, there was a general decreasing trend in the intensity of soil erosion processes in the last 63 years. The specific annual gross erosion in Grdelica Gorge was 1920.34 m 3 /km −2 /year −1 in 1953, while in 2016 it was 492.42 m 3 /km −2 /year −1 . The specific sediment transport was 1421.05 m 3 /km −2 /year −1 in 1953 and 364.39 m 3 /km −2 /year −1 in 2016. Due to the changes in the intensity of erosion processes, the specific annual gross erosion in the study area decreased by 1427.92 m 3 /km −2 /year −1 and the specific sediment transport by 1056.66 m 3 /km −2 /year −1 . The value of the erosion coefficient was reduced from Z = 0.84 in 1953 to Z = 0.32 in 2016. The results show that there is a significant correlation between the soil erosion intensity (erosion coefficient) and ECW (biotechnical works) performed in Grdelica Gorge. The permanent control of erosion processes in Grdelica Gorge is very important for torrential flood prevention and protection of two very important traffic routes (Belgrade-Skopje-Athens railway and motorway-Corridor X), as well as settlements, local roads, and other facilities in this area. Furthermore, these results are the basis for future water management projects, soil and environmental protection, spatial planning, agriculture, and other human activities.

“…The type and cover of vegetation are important factors that influence the activity of geomorphological processes by controlling the dynamics of surface runoff and sediment (Blinkova & Lavrov, 2017). The shape of the slope also has a significant impact on soil erosion and surface runoff which are greater on lands with a uniform slope than on lands with convex and concave slopes (Sensoy & Kara, 2014).…”

The utilization of steep lands by planting forestry and agricultural species can provide benefits from soil-water conservation and economic aspects. The combination of planting Neolamarckia cadamba-Phaseolus vulgaris and terrace systems can increase land use values, such as soil conservation, crop production, and farmers’ income. The aim of this study was to analyze silvicultural, hydro-orological, and economic aspects of a combination of forestry-agricultural crops (N. cadamba – P. vulgaris) and terrace systems on two slope classes. Two study plots were established on a steep gradient (25–40%) and a very steep gradient (>40%). The results showed an annual increase in the average diameter and height of N. cadamba of 1.78 cm and 1.84 m, respectively on the steep slope, and 1.68 cm and 1.53 m, respectively on the very steep slope. The surface run off and erosion rate were lower on the steep ground compared to the very steep ground. Erosion hazard indices and levels on the plots in the steep slope and very steep slope were categorized as low and very low; meanwhile the erosion hazard class was I. The profit of P. vulgaris cultivation was IDR 9,360,000.00 ha–1 per cropping season on steep slope and IDR 6,480,000.00 ha–1 per cropping season on very steep slope. The planting of P. vulgaris as an intercropping plant to fill empty land in between N. cadamba can increase the economic value obtained from selling P. vulgaris in the short term until the leaves of the N. cadamba plant are linked. The combination of planting N. cadamba–P. vulgaris and terrace system on steep slopes is therefore more profitable not only from the economic perspective, but also in lowering runoff and potential erosion rates than on very steep lands.

“…This is presumably because the loss of nutrients through harvesting, leaching, erosion, and volatilization in the crop is larger than the nutrient input through rain, organic and inorganic fertilization, and crop residues. Blinkova and Lavrov (2017) stated that non-woody plants have a high risk of nutrient leaching, erosion and runoff.…”

Degradation of soil functions in storing and cycling nutrients may be related to topography and land-use change. The research aimed to analyze the impact of land-use changes and slope positions on soil function in nutrient stock within Kalikungkuk micro watershed of East Java, Indonesia. Four different land-uses such as vegetable crops, agroforestry, shrub and forest were selected with three slope positions (e.g. ridge, slope, and valley), and three replications of each. Soil samples were collected at 0-10, 10-30, 30-50, and 50-100 cm depth of soil. Variables measured included soil properties (e.g. bulk density, soil texture, pH, CEC, soil nutrients). Slope positions impact on differences in soil physical (i.e. soil bulk density, soil texture) and chemical (i.e. total N, exchangeable K) properties. In addition, forest conversion to other land-uses (i.e. agroforestry, shrub, vegetable crops) decreased soil nutrient concentration (i.e. total C, total N, Ca, Mg, Na), and consequently resulted in degradation of soil nutrient stocks of especially C and N. The strong positive correlation between soil nutrient stock (e.g. C and N) and vegetation cover such as canopy cover, basal area, and litter (r = 0.63 – 0.78, r table 1% = 0.39) showed the benefit of biodiversity in maintaining soil function on the nutrient stock.
