Qinghai–Tibetan Plateau soils contain substantial carbon and nitrogen stocks, with >48 Pg carbon estimated in the upper 1 m of soil. Net ecosystem productivity (NEP) has increased as a result of climate change and restoration. As the increases in NEP surpass the increases in carbon losses...
The reason for this is that the soil microbial community is homeostatic, i.e., it maintains its C:N:P ratio within a small range (Xu et al., 2013; Cleveland and Liptzin, 2007). According to the concept of consumer-driven nutrient recycling, soil carbon (C) and N cycling is largely...
Fine-grained muds produced largely from rock weathering at the Earth’s surface have great influence on global carbon cycling. Mud binds and protects organic carbon (OC) from remineralization, and its organic loading controls the amounts, timescales and pathways of OC sequestration in sediments and...
This N accumulation in the soil, combined with the low-productivity and the dominant C4 grasses, which have relative low litter N concentration and thereby low fire-induced N losses, makes this successional grassland resistant to fire-induced N cycling and C and N pool changes for at least ...

Carbon and nitrogen and sulfur concentrations were measured to determine if associations existed between soil nutrient status, season, and the potential for immobilization of precipitation-borne sulfate in a forest watershed. Radiolabeled sulfate was used to assess the fate of S in soil and sediment....
This book is a single-volume treatment of the biochemical cycles in soil. It examines all major aspects of nutrient cycling, including fluxes with other ecosystems, biochemical pathways and transformation, gains and losses, chemical fixation reactions, and plant availability. It integrates environmental...
Microbial necromass is an important component of soil organic matter, however its persistence and contribution to soil carbon sequestration are poorly quantified. Here, we investigate the interaction of necromass with soil minerals and compare its persis
