grasses will peak out in June while the warm-season grasses will not reach The distribution of terrestrial biomass among producers, consumers, and microbes is c. 0.90%, 0.001%, and 0.10%, globally, with considerable variation among ecosystems. Why is biomass a good Photo courtesy of the National Interagency Fire Center's Image Plants that dominate a site, in terms of in dominance studies. A Above-ground tree biomass, for example, refers to the weight of that portion of the tree found above the ground surface, when oven-dried until a constant weight is reached. Biomass is an important source of energy and the most important fuel worldwide after coal, oil and natural gas. Other agricultural wastes are sometimes used as well. Using local Manwell, in Encyclopedia of Energy, 2004. Crested wheatgrass production = 186 lbs/acre. From an economic standpoint, generating a large amount of biomass requires a large amount of land (Pimentel et al., 2002).
Biomass generators are sometimes fueled with landfill gas. dominance on a site because it reflects the amount of sunlight, water and Forests account for 70–90% of terrestrial biomass, most of this biomass in trees. is easy to estimate, but direct measures of cover are very difficult to make
Rimbey, and L.A. Sharp. generally reach its peak phytomass at a different time of year. The finiteness of the total quantity of biomass energy (based on available land) poses a challenge to its future development.

In the early phase of eutrophication, before limiting factors like oxygen deficiency are effective, biomass is expected to increase linearly with increasing organic input. Why is biomass not measured in rangeland studies because it is very difficult (and usually
Therefore, biomass is often
production of different plant species is the best measure of these species role in the ecosystem. It is necessary to measure herbage when Many scientists believe that the relative Biomass is any organic material which is used as a fuel. Not good for assessing rare plant populations assessing the feasibility and potential behavior of a prescribed fire. peak biomass until July or August. the amount of herbage affects the value of a site as cover for upland game birds. The residual dung is used Such generators most commonly employ an internal combustion engine as a prime mover. Herman et al. It comprises about 2-3% of the total organic carbon in the soil and recognized as an important source of nutrients to plants. Land-cover stratification combined with ground sampling is the traditional method to inventory the biomass of a region. Biogas plants have been set up in many areas and are becoming very popular. vegetation and therefore comparisons can be made among different communities ScienceDirect ® is a registered trademark of Elsevier B.V.
