Resumen:
Soil carbon, multiple benefits Maintaining and increasing soil carbon content yields substantial, multiple benefits. Greater soil carbon helps to maintain soil structure by forming stable, larger aggregates that hold plant-available water in intra-aggregate pores and larger inter-aggregate pores that create greater soil permeability, aeration and drainage. Increasing soil carbon provides substrate and energy to support microbial activity, provides a reservoir of organic N, P and other nutrients for plant productivity, and creates more physically cohesive soil to resist soil losses by wind or water erosion and by protecting occluded organic matter within the larger aggregates. Carbon that enters soil is removed from the atmosphere; any gains in soil carbon mitigate greenhouse gas emissions, with caveats about impacts on the N cycle and N2O production, and production of CH4 from anaerobic decomposition of organic matter in waterlogged soils.
