Résumé
Simulation de tertre de marmottes : augmentation de la production végétale autour du tertre et augmentation des niveaux en phosphore du sol. Simulated mounds of excavated soil similar to those from woodchuck burrows and found that presence of feces in woodchuck mounds significantly increased aboveground production relative to simulated mounds without feces and increased levels of soil phosphorous.
