what is the organic constituent of soil called
Graduate study, travel, work make me an expert in benthics, European languages, wildlife mapping, world fauna and flora. Humus is what the organic constituent of soil is called. It's dark brown, fresh smelling, nutrient rich organic matter. It's formed from the break down of dead and decaying animal and plant matter, and from animal waste products, in the soil.
Soil biology is the study of microbial and faunal activity and ecology in soil.Soil life, soil biota, soil fauna, or edaphon is a collective term that encompasses all the organisms that spend a significant portion of their life cycle within a soil profile, or at the soil-litter interface.erobic bacteria are most active in a soil that is moist (but not saturated, as this will deprive aerobic bacteria of the air that they require), and neutral soil pH, and where there is plenty of food (carbohydrates and micronutrients from organic matter) available.
