soil respiration

Pedology is the scientific study of soils, encompassing their physical and chemical properties, the role of organisms, and their formation and mapping. Soil organisms, from microscopic bacteria to larger animals, are crucial for soil fertility, structure, drainage, and aeration. They break down organic matter, releasing nutrients essential for plant growth and facilitating nutrient cycles like carbon and nitrogen.12

Soil respiration is a key process where soils release carbon dioxide (CO₂) into the atmosphere as organic matter decomposes. This process is vital for the carbon cycle, but human activities like deforestation and agriculture can disrupt this balance, leading to increased CO₂ release. Soils also play a role in global warming by influencing greenhouse gas emissions like methane and nitrous oxide.34
