Inline fertilizer injector with a clear reservoir

Fertilizer injectors and mixers add a measured amount of compatible soluble fertilizer to irrigation water. Compare reservoir capacity, dilution or siphon ratio, flow and pressure requirements, hose or pipe connections, and the product directions for approved inputs. Confirm that the injector fits the watering system before purchase.

Use suitable irrigation filters and follow label directions for mixing, application, flushing, and storage. See the broader fertigation and irrigation feeding collection for compatible system components and inputs.
