A növényi anyag bomlása fontos mechanizmusa az ökoszisztémák energia- és tápanyagdinamikájának. 230 napos kísérletben vizsgáltuk a közönséges nád (Phragmites australis) három növényi részének (levél, szár és rizóma) lebontási ütemét és a visszamaradt teljes nitrogén és foszfor mennyiségét a Balaton (tó) és a Kis-Balaton (wetland) területén. A kísérlet során avarzsákos módszert alkalmaztunk, két lyukbőséggel (avarzsák lyukátmérő ø = 3 mm és planktonháló zsák lyukátmérő ø = 900 µm). A nád növényi részeinek tömegvesztése általában nem különbözött a két lyukbőségű zsák és a kísérleti területek között. A bomlási sebesség a leggyorsabb a rizóma esetében volt (k = 0,0051), míg a szárnál figyeltük meg a legalacsonyabb értékeket (k = 0,0004). A vizsgálati időszak végén a nád három növényrészében mért visszamaradt tápanyag-koncentráció eltérő volt. A balatoni nád szár esetében a nitrogén és a foszfor magasabb volt, mint a kezdeti koncentráció. A levél és a rizóma esetében csökkenés volt megfigyelhető.
