With this system, the fertilizer is gravity fed through a flexible hose and into a trough that is comfortably positioned for hand holding. The trough remains continually full but will not overflow. This allows even distribution of fertilizer and applies it where you want it. The water resistant pouch is made of 12 oz. Dupont Cordura and has a 45 lb. capacity. It is secured to an aircraft hardened aluminum self-standing frame with a combination of stitching and heavy duty webbing. It has a 2 1/2" wide, fully padded, adjustable shoulder harness system and 5" wide, fully padded, adjustable waist belt with quick release buckle.
