Abstract

Geotextiles have become a popular solution in environmental engineering. They may be manufactured from synthetic or biodegradable materials. The main functions of geotextiles are: separation, filtration, drainage, sealing, anti-erosion protection, and improving plant vegetation conditions. The synthetic ones are produced mainly from fossil fuels. One of the ways to reduce the consumption of energy from non-renewable sources and to limit environmental pollution is to replace petrochemical materials with natural products. Unfortunately, only 2% of the geosynthetics are produced from renewable resources. However, it is estimated that natural fibers and biopolymers might successfully replace synthetic materials even in 50% of all applications. A wide range of geotextiles produced from such natural fibers as jute, flax, coconut fiber, palm fiber, sisal, nettle, straw, cotton, and wool are currently available on the market but they are not widely used in environmental engineering. The paper presents the current state of knowledge and technological developments in their production and application. The study also points to the existing deficiencies and opportunities in the development of the manufacturing technology of natural fibers and biodegradable polymers.

Abstract

The aim of the study was to determine the effect of the geocomposite (GC) on macronutrient uptake of container- grown Brunnera macrophylla and substrate properties. The GC consists of superabsorbent polymer (SAP), internal skeleton and non-woven geotextile. It was designed to retain water in the soil in a form available for plants, by roots overgrowing the geotextile to access water. The GC was soaked in a multi-compound fertilizer (Insol® U) and compared with soluble fertilizer (SF) and controlled-release fertilizer (CRF). The fertilizer rates were calculated to cover the equal N supply: 0.36 and 0.72 g N plant-1. Nitrogen uptake of Brunnera cultivated with the geocomposite was approximately twice and three times as high as that of plants fertilized with SF and CRF, respectively. Exceptionally high N content was observed in plants cultivated with the GC-0.72 g N plant-1. The use of the GC also enhanced the accumulation of K and P, while CRF strongly reduced their content in plants. Distinct relations could be observed in the case of Ca accumulation. GC-0.72 g N plant-1 increased EC and water content in the medium without direct contact between SAP and substrate. [ABSTRACT FROM AUTHOR]

Abstract

The article discusses the soil substitute for grass biomass cultivation and influence of water sorbing geocomposites on it. Artificial soil for remediation purposes, soil substitutes produced by mixing organic fraction with mineral fraction, increase of water retention are also widely discussed in the article. Key condition for plant growth in soil substitutes like sufficient water, usage of geocomposites-containing superabsorbents, and migration of rain water too mentioned in the article.
