Abstract
Coir pith was considered as an agro waste in the yester years. Coir pith as an organic waste is suitable for vermicomposting, potting medium in horticulture industry and as a suitable agricultural amendment. Though coir pith is suitable for many techniques, there are also some constraints present in using the raw coir pith, such as high EC, high cation exchange capacity, low pH, high amount of soluble salts like potassium, calcium, magnesium, sodium and chloride. In order to overcome these constraints the present study was undertaken and particular issues were studied. Thus the process of pre-processing of coir pith i.e. washing the coir pith repeatedly for several times (7 times) was found effective in overcoming the constraints in the usage of raw coir pith.
