Fertilizer Injection Machines

The “pHertigater” and Ag Solution Master are used to inject a number of amendment and fertilizing materials through irrigation water. Many are compatible when mixed and injected in combination with other materials, or they may be injected alone. A jar test at diluted rates is always advisable. Materials containing phosphorous should not be mixed and injected with materials containing calcium. An added feature to the “pHertigater” is that materials in nearby and freestanding tanks may be injected through the “Gaterater” port without passing through the “pHertigater’s” tank.

Many other materials, including sea weed and fish emulsion are easily injected.
