A Novel Method for Accelerated Composting of Coir Pith

Hillocks of coir pith accumulate in the vicinity of coconut coir-fiber extraction units, of which disposal and management remain a major problem. Southern states of India, especially Kerala, Tamil Nadu, Andhra Pradesh, Karnataka, and Orissa, face this problem. A simple technology for accelerated composting of coir pith was developed, and on-site composting of coir pith hillocks was demonstrated. The composting of pith was complete in 21 days. The composted pith was an excellent organic manure, with a reduced C/N ratio of 20:1, pH of about 6.5, and electrical conductivity of 0.23 dS/cm, making it a more desirable soil organic manure. The composted pith did not contain or carry weeds and undesirable pathogens, thus providing a rich soil environment for plant and vegetation growth.
