Fiber Quality of Hemp (Cannabis sativa L.) Grown in Soil Irrigated by Landfill Leachate Water

Hemp (Cannabis sativa L.) for industrial use is often considered as a renewable resource for cultivation in polluted areas, on one hand, for the purpose of possible remediation of soil and, on the other hand, for wide options of the possible use of plant material after the harvest in such areas, namely hemp fiber. This study summarizes the effects of landfill leachate irrigation on agronomic parameters and fiber properties in two cultivars of hemp has grown and harvested in two consecutive seasons. Cultivar Bialobrzeskie shows more promising results in terms of total fiber content and phloem fiber content, while it tends to sacrifice the density of both xylem and phloem fiber in comparison to cultivar Monoica. The two cultivars also demonstrate different sensitivity and responses to the presence of heavy metals, namely zinc and chromium
