Fertigation introduces soluble nutrients into an irrigation network, so the irrigation design and nutrient-delivery method need to work as one system.
The injector or dosing method should match the available pressure, flow, farm scale and desired level of control. Compatibility with fertilizers and irrigation materials should be confirmed from product documentation.
Good practice includes filtration, controlled mixing, line flushing and a clear operating sequence. Backflow protection and safe handling are also important where the source connects to other water uses.
A fertigation quotation should identify the irrigation zones, water source, crop, existing pump or tank arrangement and the desired level of automation.
