Proportional Fertilizer Injector

The 1 Pint Automatic Proportional Fertilizer Injector from DIG Corporation, known as the ADD-IT, is the perfect solution for home gardeners looking to easily fertilize their plants. This injector can be connected to any standard 3/4" garden hose spigot or connection, eliminating the need for an outside power source. With no moving parts, the ADD-IT requires minimal maintenance and fertilizes your plants with every watering.

Key Features:

• Economical way to automatically apply nutrients to lawns, shrubs, trees, flowers, raised beds, vines, and potted plants
• Simple and easy installation process
• Constructed of heavy-walled, UV-resistant PVC for durability
• Maintenance-free operation due to lack of moving parts
• Compatible with any liquid or water-soluble dry fertilizer
• Applies fertilizer proportionately and evenly throughout drip or conventional sprinkler irrigation systems
• Ideal for residential, commercial, greenhouse, and nursery use

The ADD-IT Fertilizer Injector has been recognized with the prestigious AE50 award from the American Society of Agricultural Engineers for its innovative product design.

Please note that the unit must be installed in a vertical upright position and is not rated for use under constant pressure.

How It Works:

The ADD-IT injector does not dilute the fertilizer additive as the irrigation system operates. A small amount of water is diverted from the mainline into the canister, then forced back into the mainline. A pressure differential draws the fertilizer out from the bottom of the canister, ensuring even distribution throughout the system. The water and fertilizer solution remain separate due to their differing specific gravities, ensuring consistent distribution from start to finish.

After all the fertilizer solution is dispensed, the canister will contain only water. With its efficient design and easy operation, the ADD-IT Fertilizer Injector is a must-have tool for any home gardener looking to simplify their fertilizing routine.
