“…Yet the purpose of this study was to spur the onset of the biological activity normally present in topsoil layers (Bellgard, 1993) and not to recreate a new topsoil horizon for plant life. Compared to previous trials (Bagnaresi et al, 1992;Muzzi et al, 1997), the amount of agronomic inputs was restricted in order to limit the impact on the topsoil properties. …”

Revegetation of mineral-clay soils is a notably complex ecological and technically challenging undertaking that depends on substrate profile and local micro-environmental conditions, factors making it a particularly long procedure as well. This study compared and assessed the medium-term effectiveness of four treatments employed to promote stable pedogenesis and herbaceous recolonisation of abandoned clay quarries in the Apennine foothills of northern Italy's EmiliaRomagna region. The treatments included: slow-release N organic fertiliser, phosphate fertiliser, organic amendment and topsoil [the soil top layer (0-0.2 m) of a local natural meadow]. The state of the vegetative cover was monitored monthly from 1994 through 2004, until problems of slope stability at the site compromised the integrity of the trial plots. Significant effects were achieved by the recycled topsoil through 8 years and by organic amendment through 6 years; the effects of slow-release nitrogen were notably limited over time and phosphorous delivered a medium-term response but of notable year-toyear swings. No interactions among factors emerged in the mediumterm. After 11 years, treatments did not induce effects statistical appreciable. Our results suggest that the tested agronomic strategies on mineral clay soil did not trigger, in the medium-term, secondary succession processes able to potentially alter the spontaneous revegetation course.

“…In our study the presence of mulch improved the effectiveness of hydroseeding, as Albaladejo et al (2000) and Muzzi et al (1997) have found. Comparing the experimental tests we carried out, we note that during the rainy season, between January and March, the highest percentage of total vegetation cover was obtained in test 2.…”

“…This is a technique increasingly used to establish vegetation on degraded areas in order to provide environmental protection; in EU countries it is primarily used for embankment and slope consolidation as well as for the recovery of abandoned quarries and landfill sites, and for the planting of lawns (Muzzi et al, 1997;Bochet and Garcìa-Fayos, 2004;Oliveira et al, 2011).…”

“…Hydroseeding application in Italy was carried out in the northern Appennine region in the context of reclamation and revegetation of former quarry land (Muzzi et al, 1997), obtaining poor results in terms of ground cover, species, runoff, and erosion. Other studies performed in Italy describe the functionality of hydroseeding machines with reference to the nozzle type and the homogenization of the mixture inside the tank (Balsari et al, 2005).…”

Comparing Potential Unstable Sites and Stable Sites on Revegetated Cut-Slopes of Mountainous Terrain in Korea

This study employs a diverse set of variables to explain slope stabilization on stable versus failure-prone revegetated cut-slopes in Korea. A field survey was conducted at potential unstable sites and stable sites using 23 variables. Through a non-parametric test of the field survey results, 15 variables were identified as primary determinants of slope failure. Of these variables, one described physical characteristics (elapsed year); four variables described vegetation properties (plant community, vegetation coverage rate, number of trees, and number of herbs); and 10 variables represented soil properties (porosity, soil hardness, water content, sand ratio and silt ratio of soil texture, tensile strength, permeability coefficient, soil depth, soil acidity, salt concentration, and organic matter). Slope angle, which was mainly considered in previous studies, of variables in physical characteristics was OPEN ACCESSSustainability 2015, 7 15320 not statistically selected as one of the 15 variables because most of sites were located on steep slopes. The vegetation community, vegetation coverage, and number of trees influence slope stabilization. Vegetation coverage is highly correlated with other soil and vegetation variables, making it a major indicator of slope stabilization. All soil variables were related to slope failure such that subsequent slope failure was related to the method of slope revegetation rather than the environmental condition of the slope. Slope failure did not occur in revegetated slopes that matched the characteristics of the surrounding landscape and contained a large number of native trees. Most soil and vegetation variables showed differing values for whether a revegetated slope is potentially unstable or stable.
