Selected physico-chemical and chemical characteristics of 13 coconut coir dust (mesocarp pithy tissue plus short-length fibres) samples from Asia, America and Africa were evaluated as peat alternatives. All properties studied differed significantly between and within sources, and from the control Sphagnum peat. pH of coir dust was slightly acidic, whereas salinity varied dramatically between 39 and 597 mS m(-1) in the saturated media extract. The cation exchange capacity and carbon/nitrogen (C/N) ratio ranged from 31.7 to 95.4 cmol(c) kg(-1) and from 75 to 186, respectively. Most carbon was found as lignin and cellulose. The concentrations of available nitrogen, calcium, magnesium and micro-elements were low, while those of phosphorus and potassium were remarkably high (0.28-2.81 mol m(-3) and 2.97-52.66 mol m(-3) for P and K, respectively). Saline ion concentrations, especially chloride and sodium, were also high.
对来自亚洲、美洲和非洲的13个椰壳纤维粉尘（中果皮髓质组织加短纤维）样本的选定物理化学和化学特性进行了评估，以作为泥炭的替代品。所有研究的特性在不同来源之间、同一来源内部以及与对照泥炭藓泥炭之间均存在显著差异。椰壳纤维粉尘的pH值呈微酸性，而在饱和介质提取物中，电导率在39至597 mS m(-1)之间变化很大。阳离子交换容量和碳氮比（C/N）分别为31.7至95.4 cmol(c) kg(-1)和75至186。大部分碳以木质素和纤维素的形式存在。有效氮、钙、镁和微量元素的浓度较低，而磷和钾的浓度则非常高（磷和钾的浓度分别为0.28 - 2.81 mol m(-3)和2.97 - 52.66 mol m(-3)）。盐离子浓度，尤其是氯离子和钠离子浓度也很高。
