Geotextiles are used for separation, drainage, filtration and anti-erosion protection sealing, as well as to improve plant vegetation conditions. The research objective of this study was to verify the influence of the addition of poultry feathers on accelerating the biodegradation of nonwovens in cultivated soil. The tests were carried out in laboratory conditions and were based on the assessment of weight loss. The experiments confirmed the positive effects of the presence of waste that was rich in keratin on the time required for the biodegradation of the tested materials (the period of biodegradation was 8-24 weeks). Additionally, the influence of the biodegradation of the tested materials on the ecotoxicity was investigated and showed no negative effects on the microbiological activity (10 cfu). The research also included the determination of the carbon to nitrogen ratio of the test medium (blank, 12-14:1; with feather addition, 19-20:1). A statistical analysis revealed a correlation between the mechanical properties and the period of biological decomposition. This research was an important step for the management of poultry feather waste in agricultural applications. The tested materials could be seen an alternative that meets all ecological criteria, which seems to be a golden solution that not only allows the delivery of important nutrients to the soil, but also manages waste in an environmentally safe manner.
土工布用于分离、排水、过滤、抗侵蚀保护密封以及改善植物植被条件。本研究的目的是验证添加家禽羽毛对加速耕地土壤中非织造布生物降解的影响。试验在实验室条件下进行，基于重量损失评估。实验证实了富含角蛋白的废弃物的存在对测试材料生物降解所需时间有积极影响（生物降解期为8 - 24周）。此外，还研究了测试材料生物降解对生态毒性的影响，结果表明对微生物活性没有负面影响（10 cfu）。研究还包括测定测试介质的碳氮比（空白，12 - 14:1；添加羽毛，19 - 20:1）。统计分析表明机械性能与生物分解期之间存在相关性。这项研究是农业应用中家禽羽毛废弃物管理的重要一步。测试材料可被视为符合所有生态标准的替代品，这似乎是一个绝佳的解决方案，不仅能向土壤输送重要养分，还能以环境安全的方式管理废弃物。
