Cymbopogon citratus, commonly known as West Indian lemon grass [2] or simply lemon grass, [3] is a tropical plant native to South Asia and Maritime Southeast Asia and introduced to many tropical regions. [1] Cymbopogon citratus is often sold in stem form. While it can be grown in warmer temperate regions, such as the UK, it is not hardy to frost.
Citronella grass (Cymbopogon nardus and Cymbopogon winterianus) grow to about 2 metres (6 + 1 ⁄ 2 ft) and have magenta-colored base stems.These species are used for the production of citronella oil, which is used in soaps, as an insect repellent (especially mosquitoes and houseflies) in insect sprays and candles, and aromatherapy.
The slow rate of decomposition gradually releases plant nutrients bound up in the leaves back into the environment to be re-used by plants. Autumn leaves are often collected in gardens and farms into pits or containers for the resultant leaf mold to be used later. Oxygen and moisture are essential for leaf decomposition.
The rate of decomposition is governed by three sets of factors: the physical environment (temperature, moisture and soil properties), the quantity and quality of the dead material available to decomposers, and the nature of the microbial community itself. [64] Decomposition rates are low under very wet or very dry conditions.
Leaf litter accumulation depends on factors like wind, decomposition rate and species composition of the forest. The quantity, depth and humidity of leaf litter varies in different habitats. The leaf litter found in primary forests is more abundant, deeper and holds more humidity than in secondary forests.
Cymbopogon flexuosus, also called Cochin grass, East-Indian lemon grass or Malabar grass, is a perennial grass native to India, Sri Lanka, Burma, and Thailand. It is placed in the genus Cymbopogon (lemongrasses). Its essential oil is produced by steam distillation of the freshly cut leaves, [1] or it can be extracted using alcohol.
Decomposition microbiology can be divided into two fields of interest, namely the decomposition of plant materials and the decomposition of cadavers and carcasses. The decomposition of plant materials is commonly studied in order to understand the cycling of carbon within a given environment and to understand the subsequent impacts on soil ...
