Abstract Background and aims Research into the variability of fine‐root decomposition and nutrient cycling processes in arid and semiarid ecosystems is highly significant not only for investigations of regional and global carbon and nitrogen cycling but also for offering a theoretical basis for vegetation restoration and reconstruction. In particular, information is limited on fine‐root decomposition processes and nutrient releasing characteristics in the high‐altitude Qinghai Gonghe basin… Expand
Fine root dynamic characteristics and effect on plantation’s carbon sequestration of three Salix shrub plantations in Tibetan Plateau alpine sandy land
TLDR
The results indicated that the root system of S. psammophila, especially the fine roots, was very developed, which was conducive to soil water transportation and carbon sequestration, which showed that three Salix plantations in alpine sandy land are an important carbon pool. Expand
Root order and initial moisture status influenced root decomposition in a subtropical tree species Liquidambar formosana
Root decomposition plays an important role in biogeochemical cycles in terrestrial ecosystems. However, there is still controversy on whether low-order (finer) or high-order (coarser) roots decayExpand
Decomposition characteristics of long-established Salix psammophila sand barriers in an arid area, Northwestern China
Salix psammophila has been extensively used as a sand barrier material for various desertification control applications. Elucidating the long-term decomposition characteristics and nutrient cyclingExpand
Decomposition of roots of different diameters in response to different drought periods in a subtropical evergreen broad-leaf forest in Ailao Mountain
Abstract Root decomposition plays an essential role in the terrestrial carbon cycle, but the responses of roots of different diameters to varying drought periods are unclear. Therefore, artificialExpand

Spatial Heterogeneity of Soil Nutrients after the Establishment of Caragana intermedia Plantation on Sand Dunes in Alpine Sandy Land of the Tibet Plateau
TLDR
The results showed that the spatial heterogeneity of soil nutrients was existed in C. intermedia plantation on sand dunes, and soil “fertile islands” were formed, and the ‘fertiles islands’ were more marked on lower soil nutrients level topography positions, while it decreased towards higher soil nutrientslevel topographic positions.

Relationships between fine root dynamics and nitrogen availability in Michigan northern hardwood forests
TLDR
It is proposed that greater metabolic activity for roots in nitrogen-rich zones leads to greater carbohydrate allocation to those roots, and that a reduction in root C sink strength when local nutrients are depleted provides a mechanism through which root lifespan is regulated in these forests.
