Nutrient Injection Systems

  • This system ships via motor freight; please contact CropKing for a quote.


    CropKing's Nutrient Injection System simplifies the fertigation process by injecting concentrated fertilizer into a main reservoir tank and pumping the nutrient solution through the feed lines to irrigate the crops. The system includes a three-headed bellows pump that pulls fertilizer from two concentrate tanks and one acid concentrate tank. The fertilizer salts are split in order to prevent precipitates from forming. The pump injects the concentrated fertilizer and acid at predetermined ratios, often 1:100, in order to reach the EC and pH targets.


    Everything is tested before leaving our manufacturing facility and the system is delivered completely assembled and mounted on a steel frame. Two PVC union connectors are included; one at the water supply hookup and one coming off the American Stainless injection pump. Hot and cold-water valves on the water supply provide a method of adjusting the nutrient solution to the proper temperature ideal for root growth.


    All electrical connections are clearly marked in the drip-proof control box and complete electrical diagrams are provided with each injection system. The control panel features manual and automatic switches with indicator lights for all functions. The system is compatible with any type of 24-volt AC irrigation controller, including the iGrow 1400 and the Sterling irrigation timers. The system will supply nutrient solution at a rate of up to 17 GPM at 24 PSI to the irrigation system with up to 4 zones.


    The system also includes a bypass kit to aid in system cleanup and emergency situations. For added security, CropKing’s Injection System comes equipped with an alarm kit to alert the grower if a loss of pressure is detected. The alarm can connect to a customer supplied Sensaphone to call and alert the grower or can activate a customer supplied 115V flashing light or buzzer. Nutrient and acid concentrate tanks must be purchased separately.


    A Fertroller unit can be added, wired, and mounted to the injection unit for an additional cost. This addition provides a clear display and simple method for adjusting the EC and pH targets. Please contact CropKing for more information.
