Coir pith has high porosity and holds up to SOO% moisture that makes it a unique input as soil amendment. In addition to these important physical properties, it contains high concentration of potash which makes it more useful. However, high polyphenolic content makes raw coir-pith toxic to roots of many crops. Therefore, composting is an ideal option for its beneficial utilization in agriculture as this can help in reducing the concentration of toxic phenolics and make the plant nutrients easily available.
