“…To understand the effects of supplementary composts, it is necessary to verify geotextile quality factors, such as durability, through both eld and laboratory tests. This understanding can help improve ber-composite interactions and aid in the stabilization of slopes and potential forest recovery [35].…”

The objective of this study was to evaluate the mechanical performance of geotextiles made from natural fibers of Syagrus coronata (Mart.) Becc., Thypha domingensis, and Juncus sp. The geotextiles were treated with waterproofing resin and exposed to biodegradation for 120 days to understand their stress and strain behavior. The geotextiles was treated with colorless wood waterproofing resin by Hydronorth® to make it less permeable, delay the degradation process, and consequently increase the material's resistance to climatic variables. Subsequently, the geotextiles was subjected to natural degradation on slopes covering an area of 10m². Samples of the exposed material to the degradation processes were collected every 30 days. The findings reveal that the examined fibers, following treatment with waterproofing resin, exhibit the capability for extended utilization in the field, with Thypha fiber outperforming the other tested fibers. These results hold significant potential for the incorporation of natural fibers in endeavours related to environmental conservation.

“…However, little has been explored on the geotextiles manufacture 27 , on the development of protective compounds in order to increase the durability of natural ber geotextiles in the eld, and on the complexities of the effects of resistance and durability from the interaction with the environmental variables and the soil, since the mechanisms are measured based on empirical procedures. Although additives delay the effects of degradation, the decomposition of the material still happens, with the longterm durability of the product being affected 28 , thus, it is necessary to verify the durability of the geotextiles both in the eld and in laboratory tests to better understand ber-composite interactions, helping the slope stabilization and potential oristic recovery 29 . Therefore, to contribute to the research on the durability of geotextiles composed of natural bers, The objective of this work was to assess the resistance of a geotextile made with Thypha domingensis to degradation caused by climatic variables.…”

Geotextiles made from plant fibers creates a suitable environment for plant growth as part of soil bioengineering techniques. The faster decomposition of plant fiber geotextiles compared to synthetic ones demands the use of composites that enhance their waterproofing and extend their durability in the environment. The objective of this work was to assess the resistance of a geotextile made with Thypha domingensis to degradation caused by climatic variables. Tensile strength tests were conducted in the laboratory in order to evaluate the degradation of geotextiles treated with single and double layers of waterproofing resin. Based on Scanning Electron Microscopy (SEM) images, it was verified that applying waterproofing resin twice delays the degradation of the fibers for up to 120 days of exposure to the effects of climatic variables other than temperature. The maximum resistance losses due to the geotextile's exposure to degradation were statistically significant for the all three treatments: control-without waterproofing resin, with one layer of resin, and with two layers of resin. Therefore, waterproofing resin, as a low-cost material, provides a long-term protective solution for geotextiles made from cattail fibers.

“…This species is present in the most varied climates, mainly tropical and subtropical, adapted to different altitudes and climatic conditions (Truong 1999). It is widely used in the recovery of degraded areas, emphasizing erosion control, since its root system has many cylindrical bers capable of presenting an average tensile strength of 310 MPa (Teerawattanasuk et al 2014;Holanda et al 2020).…”

Background: The objective of this work was to evaluate the root system of Vetiver grass through different methodologies. The trench method evaluated 50 images in 10 x 10 cm squares in its vertical face. The volumetric ring method uses a metallic ring with a volume of 50 cm³ (diameter ≅ 4.6 cm and height ≅ 3.0 cm) to collect samples in the same trench´s vertical face. A hand auger hole method worked with soil samples and roots removed from the surface up to 0.50 m depth. The monolith method comprises a 0.50 m wide, 0.50 m long, and 1 m deep monolith. A spatial correlation between root volume and root area was observed in the kriging maps by the volumetric ring method. Results: The root area values for both the volumetric ring method and the hand auger hole method were similar, up to 0.10 to 0.20 m. Among the analyzed variables, the root area showed the best correlation coefficient among the analyzed root methods, especially those that use the limited spatial distribution by its sampling collection, such as the volumetric ring method and the hand auger hole method (r = 0.526).Conclusions: The studied methods can be separated into two groups: those that provide more detailed information about the behavior and distribution of the root system, such as trench and monolith methods. The trench method requires turning the soil. Both require greater spatial coverage, and therefore have greater precision, and the methods that better describe the morphological characteristics of the features, such as the volumetric ring method.
