“…The measured mechanical properties of the rope materials are introduced in Table 4 and Table 5 (according to [ 24 , 25 ] and this research). As we can see, the tension strength of wool reduced by 0.07 kN∙m −1 (10.4%) after 12 months (no defined detail location in [ 24 ]) and was practically null after 47 months (degraded, not tested) in both locations 4 and 5. The tension strength of the RNSF rope at location 4 (not buried, exposed to climate variation) reduced by 0.3 kN∙m −1 (9.09%) after 47 months.…”

“…The measurements of the tensile strength and elongation at break were carried out in accordance with the Polish standard PN-EN ISO 10319:2010 [ 23 ] with a H50K-S Hounsfield tensile machine (Hounsfield Test Equipment Ltd., Redhill, UK). The tested properties of ropes materials are also outlined in [ 24 ]. More information on nonwoven properties can be found in [ 25 ].…”

Using materials from recycling is a key part of decreasing present-day waste. It is optimal for recycled material to be used in environmental protection. This paper presents the application of geotextile ropes in erosion protection of a slope of a gravel pit. To protect the slope, thick ropes with a diameter of 120 mm made from wool and a mixture of recycled natural and synthetic fibers were used. After 47 months from installation, soil and rope specimens were taken from the slope parts with inclinations 1:1 and 1:1.8, and their physical and mechanical properties were determined. Direct shear tests were applied to determine the soil shear strength parameters in state at sampling and at Ic = 0 (unconsolidated and consolidated). Based on the obtained soil shear strength parameters, the loads on the ropes were determined, taking into account also unfavorable hydraulic conditions and compared to rope strength. It was shown that even after 47 months from installation, rope tension strength was higher as tension forces were induced in the ropes in every case. At present, whole slopes in protected sections are stabilized, without rills and gullies.

“…Therefore, the use of geo-textiles could emerge as an interesting alternative to ploughing or the use of herbicides to control weeds, improve organic carbon stores, and enhance infiltration and soil aggregate stability (Broda et al, 2017; Cheah et al, 2017; Faure et al, 2010). However, more research is needed to understand better the cost-effectiveness and acceptance of geo-textiles for agricultural applications.…”

Soil erosion presents a pressing global issue that gravely impacts agriculture, food security, and the environment, necessitating immediate attention. Exploring innovative alternatives to combat soil degradation effectively is imperative while ensuring sustainable soil management. This study aims to investigate the feasibility of utilizing geo-textiles as a sustainable solution for soil erosion compared to conventional methods like weeding. The primary objective is to assess the economic efficiency of geo-textiles and rank them against traditional approaches. To achieve these objectives, we have developed mathematical models to evaluate and rank the alternatives comprehensively. The study utilized the Single Price Model method to establish a complete ranking of the alternatives. By considering economic efficiency as a key criterion, geo-textiles demonstrated their potential as a viable solution for soil erosion management, with model 4, geo-textiles made from recyclable materials, being the most efficient model of the geo-textiles studied behind the traditional plough. In conclusion, geo-textiles offer a promising alternative to traditional weeding methods, demonstrating their potential for economic efficiency and sustainable soil management. This study’s results underscore the importance of adopting innovative approaches to combat soil erosion, providing crucial guidance to decision-makers and practitioners in pursuing sustainable agricultural practices.

“…At present, loess slope protection technologies are mainly focused on theoretical studies, such as slope stability mechanisms [ 10 ], water-soil erosion control [ 11 ], biological protection by vegetation [ 12 ], and the root–soil system model [ 13 ]. In terms of practical materials and technology, various traditional treatment methods for loess slope protection (e.g., anti-slide piles, geogrid, and retaining walls) have been widely applied to improve soil strength and stability [ 14 , 15 ] and reduce soil erosion [ 16 ]. However, these treatments can not completely address water and soil erosion problems and achieve the long-term stability of loess slopes.…”

In the Loess Plateau region, the poor structure and properties of loess slopes will cause many types of geological disasters such as landslides, mudflow, land collapse, soil erosion, and ground cracking. In this paper, an eco-friendly polymer composite fertilizer (PCF) based on corn straw wastes (CS) and geopolymer synthesized from loess was studied. The characterization by FT-IR of the PCF confirmed that graft copolymer is formed, while morphological analysis by scanning electron microscopy and energy dispersive spectroscopy showed that geopolymer and urea were embedded in the polymer porous network. The effects of PCF contents on the compressive strength of loess were investigated. The PCF was characterized in terms of surface curing test, temperature and freeze-thaw aging property, water and wind erosion resistance, and remediation soil acidity and alkalinity property, which indicates that PCF can improve loess slope fixation and stability by physical and chemical effects. Moreover, the loess slope planting experiment showed that PCF can significantly increase the germination rate of vegetation from 31% to 68% and promote the survival rate of slope vegetation from 45.2% to 67.7% to enhance biological protection for loess slopes. The PCF meets the demands of building and roadbed slope protection and water-soil conservation in arid and semi-arid regions, which opens a new application field for multifunctional polymer composite fertilizers with low cost and environmental remediation.
