A standing crop is the total biomass of the living organisms present in a given environment. [1] ... "Standing crop and importance of zooplankton in a system of ...
Short rotation coppice. A field of coppiced poplar in Hampshire. Short rotation coppice (SRC) is coppice grown as an energy crop. This woody solid biomass can be used in applications such as district heating, electric power generating stations, alone or in combination with other fuels. Currently, the leading countries in area planted for energy ...
Species used. SRF is the practice of cultivating fast-growing trees that reach their economically optimum size between 8 and 20 years old. Species used are selected on this basis and include alder, ash, southern beech, birch, Eucalyptus, poplar, willow, [1][2] new varieties of Paulownia elongata, paper mulberry, Australian blackwood and sycamore.
Biomass heating system. Biomass heating systems generate heat from biomass. The systems may use direct combustion, gasification, combined heat and power (CHP), anaerobic digestion or aerobic digestion to produce heat. Biomass heating may be fully automated or semi-automated they may be pellet-fired, or they may be combined heat and power systems .
The Alpena biorefinery plant in the USA. A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)".

Standing crop biomass – Unlimited growth is an exponential process, which means that the amount of biomass determines the production. Because an increased biomass implies higher respiration per surface unit and a limited increase in intercepted light, crop growth is a sigmoid function of crop biomass.
Bioenergy. Bioenergy is a type of renewable energy that is derived from plants and animal waste. [1] The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood ...
The term second-generation biofuels is used loosely to describe both the 'advanced' technology used to process feedstocks into biofuel, but also the use of non-food crops, biomass and wastes as feedstocks in 'standard' biofuels processing technologies if suitable. This causes some considerable confusion. Therefore it is important to distinguish ...
