Coconut husk is emerging as a rich resource for a variety of products as well as soil-less gardening. The coconut fibre has been known since long as raw material for a large number of products such as ropes, coir mats, coir mesh, bio-filter and even yarn that could go into rough linen. Cocopeat (a mixture of dust as well as the non-useable fibre ends) is of late emerging as the choice for non-terrestrial plants, mainly for urban homes where space constraints force people to look for alternative material.
Normally the fibres around the coconut kernel comprise one-third of husk. The remaining two-thirds consist of dusty contents which are extremely rich in nutrients. Several entrepreneurs are now eyeing an opportunity to use the cocopeat for a variety of products. It has come to be used in a big way for hydroponic (soil-less) cultivation.
A kilogram of cocopeat is said to be capable of absorbing seven litres of water and retaining it for several months. Cocopeat is now being compacted into solid blocks for commercial purposes. It sees 17-fold volumetric expansion when treated with water. High porosity of the coco peat substratum allows good air circulation and quick vegetative propagation when planted with saplings. Besides, it is rich in nutrients such as nitrogen, potassium, phosphorous, magnesium, zinc and other necessary substances for farming.....Read more
