A global budget for fine root biomass, surface area, and nutrient contents.
Global biogeochemical models have improved dramatically in the last decade in their representation of the biosphere. Although leaf area data are an important input to such models and are readily available globally, global root distributions for modeling water and nutrient uptake and carbon cycling have not been available. This analysis provides global distributions for fine root biomass, length...
متن کاملLitter fall , Fine Root Biomass and Soil Nutrient Returns in Van Panchayat Forest of Uttarakhand
The litter fall and fine root biomass is needed to quantify the annual return of elements and organic matter to the soil. The tree species that covers the largest area in the present studied community managed forest are the common banj oak and chir pine. The mean annual litter fall in Anriyakot Van Panchayat forest was 6.25±0.26 t ha. The mean litter fall value was higher in the summer season (...
متن کاملStimulated fine root growth benefits maize nutrient uptake under optimized nitrogen management
Optimized nitrogen (N) management reduces total N application without sacrificing cropyield. However, the underlining mechanisms have not been well investigated, especially lackingthe evidence from roots. Here we performed a two-year field experiment with maize grownunder zero-N, conventional N and optimized N applications and examined grain yield, N,phosphorous (P) and potassium (K) uptake and...
متن کاملImplications of a large global root biomass for carbon sink estimates and for soil carbon dynamics.
Recent evidence suggests that significantly more plant carbon (C) is stored below ground than existing estimates indicate. This study explores the implications for biome C pool sizes and global C fluxes. It predicts a root C pool of at least 268 Pg, 68% larger than previously thought. Although still a low-precision estimate (owing to the uncertainties of biome-scale measurements), a global root...
متن کاملGlobal burned area and biomass burning emissions from small fires
Global burned area and biomass burning emissions from small fires" (2012). NASA Publications. Paper 144. [1] In several biomes, including croplands, wooded savannas, and tropical forests, many small fires occur each year that are well below the detection limit of the current generation of global burned area products derived from moderate resolution surface reflectance imagery. Although these fi...
