Nitrogen fertilization decreases forest soil fungal and bacterial biomass in three long-term experiments
We examined the effects of N fertilization on forest soil fungal and bacterial biomass at three long-term experiments in New England (Harvard Forest, MA; Mt. Ascutney, VT; Bear Brook, ME). At Harvard Forest, chronic N fertilization has decreased organic soil microbial biomass C (MBC) by an average of 54% and substrate induced respiration (SIR) was decreased by an average of 45% in hardwood stan...
متن کاملRoot biomass and exudates link plant diversity with soil bacterial and fungal biomass
Plant diversity has been shown to determine the composition and functioning of soil biota. Although root-derived organic inputs are discussed as the main drivers of soil communities, experimental evidence is scarce. While there is some evidence that higher root biomass at high plant diversity increases substrate availability for soil biota, several studies have speculated that the quantity and ...
متن کاملSap flow estimates of stand transpiration at two slope positions in a Japanese cedar forest watershed.
We determined the amount of information needed to estimate watershed-scale transpiration in a Japanese cedar (Cryptomeria japonica D. Don) forest from sap flow measurements of individual trees. Measurements of tree biometrics (diameter at breast height (DBH) and tree sapwood area (AS_tree)), and tree-to-tree and radial variations in xylem sap flux density (Fd) were made in two stand plots, an u...
متن کاملCellulose utilization in forest litter and soil: identification of bacterial and fungal decomposers.
Organic matter decomposition in the globally widespread coniferous forests has an important role in the carbon cycle, and cellulose decomposition is especially important in this respect because cellulose is the most abundant polysaccharide in plant litter. Cellulose decomposition was 10 times faster in the fungi-dominated litter of Picea abies forest than in the bacteria-dominated soil. In the ...
متن کاملSoil Organic Carbon Stocks and Nitrogen Content Comparison in Different Slope Positions in Native Grasslands and Adjacent Cultivated Soils (Case Study: Kermanshah Mountain Rangelands, Iran)
Global warming has been largely driven by increasing atmospheric GHG (Green House Gasses), particularly carbon dioxide caused by fossil fuels burning. The current trend can not be stopped except by reducing fossil fuel consumption or storing organic carbon in soil or earthchr('39')s biological systems such as forests, rangelands and agricultural systems. This study was conducted to determine th...
