NJect LF by Capstan Ag Systems as the Next Generation in liquid fertilizer application technology.  It is available as an after-market installation by Capstan dealers on any OEM model toolbar, planter or air seeder.  NJect LF technology is a simple, clever automatic “orifice” changer.   No more need to change orifices for different rates or speeds.  In most cases, each toolbar LF outlet has its own PWM solenoid valve controlling that outlet flow which results in a low COV (coefficient of variance) across the implement independent of terrain.  Thus, with accurate and even placement across the implement, immediate ON/OFF overlap control per toolbar section, and a 25:1 variable rate range, NJect LF advances fertilizer application technology to keep pace with modern fertilizer application demands.
