Geochemical analysis of selected plant fibres used as geotextiles for erosion control was conducted to evaluate their geochemical composition and to determine the elements that could potentially be nutrients for plants or cause heavy metal contamination in soils. Analysis of the samples was performed using X-ray Diffraction and X-ray Fluorescence spectrometry. Results revealed that potassium concentrations varied from 3.63% in jute-mat (India)-50.73% in banana-leaf (Sao Romao, Brazil), with a mean of 27.17%. Similarly, calcium concentrations varied from 0.09% in banana-leaf (Sao Romao) –37.0% in banana-leaf/stem (Oleo, Brazil). Iron concentrations varied from 0.15% in banana-leaf/stem samples (Oleo) –4.47% in jute-cloth (India). Since banana-leaf/stem had the highest concentration of macro-nutrients, it is therefore proposed that banana-leaf has the highest potential for adding nutrients to the soil system when biodegraded. In addition, heavy metal analysis of the samples revealed that none of the fibres have high concentrations that may contaminate the soil upon decomposition.

香蕉、布里提棕榈、黄麻和椰壳纤维的地球化学特征，用作控制侵蚀的生物地纺织品

对用作控制侵蚀的土工织物的选定植物纤维进行地球化学分析，以评估其地球化学成分，并确定可能成为植物养分或导致土壤重金属污染的元素。使用 X 射线衍射和 X 射线荧光光谱法对样品进行分析。结果显示，钾浓度从黄麻垫（印度）的 3.63%-香蕉叶（巴西圣罗马）的 50.73% 不等，平均值为 27.17%。同样，钙浓度从香蕉叶（Sao Romao）中的 0.09% 到香蕉叶/茎（Oleo，巴西）中的 37.0% 不等。铁浓度从香蕉叶/茎样品（油橄榄）中的 0.15% 到黄麻布（印度）中的 4.47% 不等。由于香蕉叶/茎含有最高浓度的常量营养素，因此，建议香蕉叶在生物降解时最有可能向土壤系统添加养分。此外，样品的重金属分析表明，没有一种纤维的浓度很高，分解后可能会污染土壤。
