The biological activity of humic matter extracted from pasture and forested alpine soils, located in a unique climatic area, was investigated with Picea abies seedlings and Zea mays roots. The humic extracts were characterized by 13 C-NMR-spectra and by the amount of indole-3-acetic acid (IAA). Results evidenced that the forest humus, endowed with a higher phenolic C and IAA content, exhibits a better influence on peroxidase activity, esterase and peroxidase polymorphism and redox membrane activity

Abstract
The biological activity of humic matter extracted from pasture and forested alpine soils, located in a unique climatic area, was investigated with Picea abies seedlings and Zea mays roots. The humic extracts were characterized by 13 C-NMR-spectra and by the amount of indole-3-acetic acid (IAA). Results evidenced that the forest humus, endowed with a higher phenolic C and IAA content, exhibits a better influence on peroxidase activity, esterase and peroxidase polymorphism and redox membrane activity
