Abstract
Aim of the study: Newly formed earth structures such as ski slopes are areas causing difficulties in attempts for efficient sodding since colonization with plants, their initial development and adaptation are hindered due to unfavorable climatic and soil factors. The main aim of the study was to demonstrate the feasibility of using nonwoven fabrics made from sheep's wool and waste poultry feathers on steep-gradient mountain slopes. Material and methods: Biodegradable geotextiles can be used not only to protect seeds and soil from washout, but also to promote turf development and improve soil microbial quality. During the experiment, plant growth was monitored together with microbial frequency changes. Results and conclusions: The results showed that the application of nonwoven fabrics after sowing a mix of grasses and clover had many advantages including the acceleration of seedling germination, improvement of plant initial development and increase of the number of plants per m2. The final biostimulation effect was found to be strongly dependent on geotextile biodegradability, grammage and the fleece structure. The best yield was obtained with the nonwoven grammage within the range of 150 - 180 g·m-2. The promotion of plant growth and, in particular, the development of the root system had a significant positive impact on the population of soil microbiota.
