Purpose: Concerns over the quantity of available freshwater for agriculture have triggered the development of technologiesintended to increase efficiency of water use, especially with regard to irrigation. A new technique called fertirrigation hasbeen developed to use the same irrigation equipment for fertilization. Methods: Since the above-mentioned techniquerequires care during installation and use on farms, current analysis focuses on some of its characteristics. Results: Highuniformity irrigation systems provide the best distribution of fertilizers, especially when used in combination with dripirrigation or micro-aspersion. The factors purity, compatibility, acidification, salinity, and solubility should be taken intoaccount. Conclusions: Fertirrigation provides a significant increase in productivity as it allows for highly controlled nutrientapplication during the entire growing season. However, it may cause serious problems if misused or overused.
