Evidence: 100 • authority: 72

Miscanthus × giganteus, also known as the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of 3–4 metres (13 ft) in one season (from the third season onwards). Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass. Miscanthus × giganteus' perennial nature, its ability to grow on marginal land, its water efficiency, non-invasiveness, low fertilizer needs, significant carbon sequestration and high yield have sparked significant interest among researchers, with some arguing that it has "ideal" energy crop properties. Some argue that…

Energy crops are low-cost and low-maintenance crops grown solely for renewable bioenergy production (not for food). The crops are processed into solid, liquid or gaseous fuels, such as pellets, bioethanol or biogas. The fuels are burned to generate electrical power or heat. The plants are generally categorized as woody or herbaceous. Woody plants include willow and poplar, herbaceous plants include Miscanthus x giganteus and Pennisetum purpureum (both known as elephant grass). Herbaceous crops, while physically smaller than trees, store roughly twice the amount of CO2 (in the form of carbon) below ground compared to woody crops. Through biotechnological procedures such as genetic modificati…

Significant difference in Miscanthus species root carbon exudation rate.. Background and aims The cultivation of Miscanthus, a giant perennial grass and promising biomass crop, is expected to increase globally in response to climate mitigation policies and sustainable agriculture goals. Little is known about root carbon (C) exudation and fine root architecture or how this might differ between Miscanthus species. To understand the functional biology of three diverse Miscanthus species and to evaluate impacts on soil C cycling, the aim of this study was to quantify root C exudation rates and track fine root growth. Methods We use a controlled environment with plants grown in rhizotron boxes (…

Restoring degraded agricultural peatlands: how rewetting, biochar, and iron sulphate synergistically modify microbial hotspots and carbon storage.. The draining and conversion of peatlands for agriculture has led to their degradation globally, diminishing their carbon (C) storage capacity and functioning. However, rewetting, alongside the addition of organic/inorganic amendments, has the potential to accelerate peat formation and C accrual. The aim of this experiment was therefore to examine the combined benefits of altering water table depth and adding organic (e.g., biochar, paper waste, biosolids, cereal straw; 20 t C ha -1 ) and inorganic (e.g., FeSO 4 ; 0.5 t ha -1 ) materials on net C…

Biochar mitigates the peatland GHG dilemma under contrasting water table regimes: phase-dependent responses of CO<sub>2</sub> and CH<sub>4</sub> over a two-year study.. Peat soils are major terrestrial carbon stores, yet drainage alters redox conditions that stimulate CO 2 , CH 4 , and N 2 O emissions. We conducted a two-year mesocosm experiment to quantify how water table level (0, 20, and 40 cm) interacts with organic amendments to regulate gaseous C and N fluxes from lowland peat. Amendments included Miscanthus biochar, Miscanthus chip, paper waste, biosolids, and cereal straw. Results revealed that moderate drainage (WTL 20 ) provided the optimal balance between…

In the context of energy production, biomass is matter from recently living (but now dead) organisms which is used for bioenergy production. Examples include wood, wood residues, energy crops, agricultural residues including straw, and organic waste from industry and households. Wood and wood residues is the largest biomass energy source today. Wood can be used as a fuel directly or processed into pellet fuel or other forms of fuels. Other plants can also be used as fuel, for instance maize, switchgrass, miscanthus and bamboo. The main waste feedstocks are wood waste, agricultural waste, municipal solid waste, and manufacturing waste. Upgrading raw biomass to higher grade fuels can be achie…
