Fertilizer injectors are mechanical devices used to apply water-soluble fertilizers, pesticides, plant growth regulators, wetting agents, disinfectants, and mineral acids—and are a vital part of modern greenhouse operations.

This comprehensive 24-page publication contains detailed illustrations of how injectors work, as well as guidelines for choosing, installing, and maintaining an injector. Additional guidelines for calibrating and checking water flow rate; includes tables of concentration of water-soluble fertilizer, fertilizer injector companies, and metric conversions.
