2 juli 2007 20.30 Lise Fivez van de universiteit van Antwerpen is 3 dagen op bezoek om een experiment op te zetten. Ze gaat planten kweken op een voedingsoplossing die verrijkt is met een stabiel isotoop van stikstof (N15). Deze planten worden dan als strooisel op begraasde en onbegraasde vegetatie gelegd. De afbraak van de planten is dan te vervolgen doordat het isotoop van stikstof terug te vinden is in de bodem, in het mos of in nieuw groeiende planten.Eerst moet ze zand verzamelen waarin de planten geplant kunnen worden. Dat is nog niet zo eenvoudig want hier is de bodem voornamelijk bestaande uit stenen en ijs. |
