Humus en forêt : Tout savoir sur les humus - Pédologie #1

This video on forest humus will give you the keys to recognizing the different soil layers (OLN, OLV, OF, OH) and identifying the type of humus using a simplified identification key used in forest soil science. 🌱 We'll see what is taught in the BTS Forest Management program regarding soil horizons, and how humus and indicator flora allow us to assess the chemical richness of forest soil. #humus #soil #forest #pedology #ecology #nature #science #earth #biodiversity #forester #organic #garden 👉 In this video, you will learn to recognize: the different organic horizons (OLN, OLV, OF, OH) the A horizon (organo-mineral) the key for identifying aerated lowland humus (Brêthes & Jabiol) the main types of humus: eumull, mesomull, oligomull, dysmull, hemimoder, eumoder, dysmoder, and mor. 🌳 This video is ideal for: students and technicians in Forest Management BTS programs, those passionate about soils, forests, and forest ecology, and anyone who wants to better understand the fertility and life of forest soils.
