Megfigyelésünkben a FAO-56 módszer néven ismert Penman-Monteith egyenletet és annak egy lehetséges gyakorlati alkalmazását mutatjuk be hazai példán. A dolgozat célja a FAO-56 módszer helybeli alkalmazhatóságának áttekintése, valamint egy gyakorlati példa alapján történő felhasználása volt. A referencia evapotranspiráció és a növénykonstans segítségével meghatározhatjuk egy adott növény faj tényleges párolgását különböző időintervallumokra. A napi nád párolgását evapotranszspirométerben mértük, melyből a nád növénykonstansait származtattuk. Bár megfigyelésünkben a cél nem a konkrét ETc meghatározás volt, a mintapéldánk alapján 2007-ben a nád párolgása mintegy 30%-kal meghaladta a szabad vízfelület evaporációját, mely összhangban van a korábbi irodalmi adatokkal.
