The technique of encapsulation of fertilizers as a coir based product is an effective and economical method for overcoming some management problems associated with fertilizer applications. Totally cut down labour charges associated with repeated fertilizer applications, reduction of fertilizer cost by 20%, prevention of environmental hazards and wastage due to extreme leaching loss of nutrients, prevention of possible pilferage and adulteration of fertilizers are some of the benefits associated with fertilizer encapsulated coir bricks.
