Abstract Since the late 1950s, governmental rangeland policies have changed grazing management on T ibetan P lateau ( TP ). Increasing pressure and, since 1980s, privatization and fencing of pastures near villages has led to land degradation, whereas remote recovered from stronger overgrazing. To clarify effect moderate carbon C ) cycle , we investigated differences in below‐ground stocks allocation using situ 13 CO 2 pulse labeling (i) a montane K obresia winter pasture yaks, with regime...
Increase of belowground C allocation by plants under global warming or elevated CO2 may promote decomposition soil organic carbon (SOC) priming and strongly affects SOC dynamics. The specific effects depend on the amount frequency inputs. Most previous studies have investigated single additions, but they are not very representative for litterfall root exudation in many terrestrial ecosystems. We evaluated (13)C-labeled glucose added to three temporal patterns: single, repeated, continuous...
Stoichiometric control of input substrate (glucose) and native soil organic C (SOC) mineralization was assessed by performing a manipulation experiment based on N or P fertilization in paddy soil. Glucose increased with nutrient addition up to 11.6% combined application compared that without addition. During 100 days incubation, approximately 4.5% SOC mineralized stimulated glucose exponentially dissolved (DOC):NH4+-N, DOC:Olsen P, microbial biomass (MB)C:MBN ratios. The relative abundances...
When glaciers retreat they expose barren substrates that become colonized by organisms, beginning the process of primary succession. Recent studies reveal heterotrophic microbial communities occur in newly exposed glacial before autotrophic succession begins. This raises questions about how function absence carbon inputs from autotrophs. We measured patterns soil organic matter development and changes community composition use along a 150-year chronosequence retreating glacier Austrian Alps....
Summary 1. Plant–microbe competition for available nitrogen (N) has been suggested to be an important mechanism controlling N limitation of plants in a variety ecosystems. However, spatio‐temporal patterns between and microbes soil remain unclear. 2. Short‐term 15 tracer experiments were conducted during growing season (July, August September) alpine meadow on the Tibetan Plateau unravel plant–microbe NH 4 + NO 3 − . 3. Alpine poorer competitors than microorganisms inorganic July compared...
Abstract Decomposition of organic matter (OM) in soil, affecting carbon (C) cycling and climate feedbacks, depends on microbial activities driven by C nitrogen (N) availability. However, it remains unknown how decomposition various OMs vary across global supplies ratios N inputs. We examined OM incubating four types (leaf litter, wood, from mineral horizons) a decay continuum subtropical forest at Ailao Mountain, China with labile additions. wood high C:N decreased for 3.9 to 29% these...
Evidence shows that many tree species can take up organic nitrogen (N) in the form of free amino acids from soils, but few studies have been conducted to compare and inorganic N uptake patterns temperate tropical relation mycorrhizal status successional state. We labeled intact roots by brief 15N exposures using field hydroponic experiments a forest China. A total 21 dominant were investigated, 8 13 forest.

Assessment of soil health requires complex evaluation properties and functions responsible for a broad range ecosystem services. Numerous quality indices (SQI) have been suggested the specific groups functions, but comparison various SQI is impossible because they are based on combination properties. To avoid this problem, we suggest an SQI-area approach areas radar diagram chemical, biological physical The new independent principle allows rapid simple parameter soils. Another analyzing...
