   Soil organic matter (SOM) dynamics play a major role in natural ecosystems and extensive agriculture. In intensive agricultural systems with high fertilization rates, the various organic components have the potential for acting as a temporary nutrient reservoir. The proper

   Feb 1, 1998 · Because human modifications of land use, such as the replacement of natural ecosystems with agroecosystems, have the potential to dramatically alter soil organic matter (SOM) dynamics in these soils (Schlesinger, 1984), estimating SOM pools and turnover rates in natural and human-influenced systems is fundamental to our ability to estimate ...

   Jan 1, 1997 · These responses, individually and interactively, affect soil health or quality. In this chapter, we focus specifically on temporal changes in soil organic matter (SOM). Organic matter merits attention, because it is widely perceived as an indicator of soil productivity (Johnston, 1991).

   Are soil organic matter Dynamics primarily under biological control?

   • Overall, a new paradigm is emerging that soil organic matter dynamics and stocks are primarily under biological control, with implications for management of the valuable soil resource. Organic matter, the major product of life, is mainly made from six chemical elements: carbon, hydrogen, oxygen, nitrogen, sulphur, and phosphorus.

   How do soil organic matter models work?

   • Soil organic matter models are based on a carbon flow that is derived from litter input. Additional processes of carbon input, like the direct carbon uptake of methane and CO 2 by soil microorganisms (see above), are all lumped into a stable carbon pool.

   How does soil organic matter dynamics relate to exponential decay functions?

   • Our general established view of soil organic matter dynamics is related to exponential decay functions. It assumes that carbon added to the soil is decomposed with a constant decay rate (K) (Eq. 1). C is the carbon concentration at a given time point (t) in years and C 0 is the initial carbon concentration.

   Why is organic matter important?

   • Organic matter merits attention, because it is widely perceived as an indicator of soil productivity (Johnston, 1991). Furthermore, SOM is mutable and very responsive to external influences; many indices of soil quality are fixed, but SOM can be altered, particularly in agroecosystems.
