In china’s loess plateau, afforestation and reforestation are considered the foremost practices for sequestering carbon and conserving soil and water. In order to evaluate the carbon storage changes of tree, soil, and litter, and the soil total nitrogen (stn) in two typical artificial forests in the region, we conducted plot surveys for different ages of both artificial forest types.

Further, 28% of the population is chronically hungry and over half of people are living on less than us$ 1 per day as a result of soil fertility depletion.
The ubiquitous occurrence of a long-lived soil oc pool suggests soil oc is globally vulnerable to perturbations by future temperature and precipitation increase. Scaling of riverine biospheric-carbon ages with soil oc turnover shows the former can constrain the sensitivity of carbon dynamics to environmental controls on broad spatial scales.
The integrated biosphere simulator (or ibis) is designed to be a comprehensive model of the terrestrial biosphere.

Soil carbon (c) is mostly bound in what we call “soil organic matter”, or som—although carbonate (co3) minerals also contribute to soil c storage. Som is composed of dead biomass (detritus) from roots, plant litter, animals, and microorganisms, plus live microorganisms that actively consume and produce a diverse mixture of c-containing.
This makes soils a critical component of the global carbon cycle. Soil carbon (c) is mostly bound in what we call “soil organic matter”, or som—although carbonate.

Integrated crop-livestock systems can have subtle effects on soil quality over time, particularly in semiarid regions where soil responses to management occur slowly. We tested if analyzing temporal trajectories of soils could detect trends in soil quality data which were not detected using traditional statistical and index approaches.

Research over the past several decades has clarified the mechanisms and timescales involved in stabilizing organic matter in soils, but we still lack process-based understanding sufficient for predicting how vulnerable soil carbon (c) is, given climatic or environmental change across a range of soil types and landscapes. Part of the problem is the emphasis on short-term studies and processes.
Insufficient characterization of soil organic carbon (soc) dynamics in semi-arid climates contributes uncertainty to soc sequestration estimates.
