ravinnekierron
Ravinnekierron, commonly referred to in English as nutrient cycling, is the movement and transformation of chemical elements and compounds, including both inorganic forms and organic matter, within an ecosystem. It encompasses the uptake of nutrients by living organisms, their incorporation into biomass, and the release of nutrients back into the environment through decomposition, mineral weathering, and other processes. The most studied elements include nitrogen, phosphorus, carbon, sulfur, and potassium, though many other nutrients participate in cycles.
Key processes include mineralization and immobilization by microbes, plant and microbial uptake, nitrification and denitrification for
In agriculture and forestry, managing ravinnekierron aims to sustain fertility while limiting losses, through practices such
