Fertigation Water

Fertigation water is the water used for fertigation (the combined irrigation and fertilisation). In the SSWM toolbox, it refers to wastewater that has been partly treated but still contains sufficient nutrients to be used in fertigation. Fertigation water, depending on its initial composition, should have undergone both physical treatment, to prevent clogging of the irrigation system, and biological treatment to reduce pathogens and to limit the risk of crop contamination and the health risk to workers and end consumers.
