1. Soil organic carbon and its dynamics
Organic carbon enters the soil primarily in the form of plant
litter and root exudates. These plant-derived materials are biotransformed
and mineralized by soil organisms, mainly micro-organisms (bacteria
and fungi). Soil organic matter (the main functions of which are presented
in figure 1) is
therefore mainly composed of living and dead biomass, decaying plant
litter, and substances of microbial origin.
