ABSTRACT

Coir pith, a biomass residue, is generated as a byproduct during extraction of coir fiber from coconut husk. It is considered as a waste in coir industry. Larger quantity production of coir pith may cause environmental pollution because of improper management of the coir pith which is not naturally degradable. Present paper deals with the utilization of the coir pith as a plant growing medium. Different parameters such as pH and conductivity of the coir pith were tested to confirm the source of micronutrient in it for the plants. These parameters were controlled by washing in subsequent stage. The retentivity of the coir medium was also tested to check water holding capacity of the medium. The obtained results showed that the parameters are not only depending on the washing but also on the size of the coir pith particle.

摘要

椰壳纤维是一种生物质残渣，在从椰子壳中提取椰壳纤维的过程中作为副产品产生。它被认为是椰壳工业的废物。由于对不可自然降解的椰壳的管理不当，大量生产椰壳可能会造成环境污染。本论文涉及利用椰壳作为植物生长介质。测试了椰壳的不同参数，例如 pH 值和电导率，以确认植物中微量营养素的来源。这些参数通过后续阶段的洗涤来控制。还测试了椰壳介质的保持力以检查介质的持水能力。所得结果表明，参数不仅取决于洗涤，还取决于椰髓颗粒的大小。
