NJect LF technology uses Blended Pulse technology as a simple, clever way to change the flow through an orifice as if the orifice size could be changed "on-the-go". It responds as needed up to a 25:1 range of rate for a variable rate map prescription
The liquid fertilizer is pumped to the input of the distribution manifold. Side-by-side flow indicators distribute the flow and give a visual flow confirmation. At the top of each flow indicator is a NJect LF PWM Solenoid that serves to regulate the liquid flow. The liquid exits out the back side of the solenoid housing and travels down a tube to the point of contact with the soil. Performance features inherit in this simple, yet innovative design include:
Automatic rate change: Rate management starts with the rate controller. The rate controller may be set up for a single rate, or to respond to rate changes dictated by a prescription map. A flow increase/decrease signal is sent by the rate controller to the NJect LF computer. The NJect LF instantaneously adjusts the solenoid response to execute the required flow. No need to change orifices for the different rates!
- Even flow distribution across the tool bar is achieved by the metering accuracy and speed of the PWM solenoids.
- Instant ON/OFF at the ground is achieved by the solenoid immediate OFF/ON response coupled with capillary action of the supply tubes.
- Significant overlap savings control occurs when the rate controller is loaded with swath control software, like Accuboom. That software communicates with the NJect LF solenoids to automatically and instantaneous turn OFF and ON as required by an As-Applied map.
- Overlap savings control can be configured by NJect LF by tool bar section with the number of sections depending on the rate controller capabilities. NJect LF permits customization of the tool bar to define the number of knives/coulters per section.
Result: Operators now have more control over placement and rates for a more accurate and precise application of fertilizer without having to ever leave the cab. Overall, users of NJect LF application technology have seen a significant reduction in their input costs and an overall improvement efficiency and quality of the application.
