grasgroei | 18 juli 2017 |
Meten hoe hard het gras groeit, geeft altijd veel reacties. Vandaag doet Mari de metingen. In twaalf gepaarde plotjes zijn vier spruiten per plot geringd. De ene plot is begraasd, de andere is omgaasd en daarmee is ganzenbegrazing uitgesloten. Op dit moment groeit het gras iets minder dan 2 mm per dag. | |
