l), our knowledge of the turn-over of forest soil humus is very incomplete. This is particularly true of the organic matter in soil horizons below the humus layer.

HUMUS decomposition under bare fallow has now been measured during five successive wet and dry seasons. Soil samples were taken periodically (about once a week during the wet season) and put in ...

Therefore, the stability of boreal soils is critical to understanding global carbon cycle feedbacks to climate change and soil management. However, the regulating factors of humus carbon ...
