Colombo Rowing Club
The Colombo Rowing Club (commonly known as CRC) is the premier boat club in Sri Lanka having been founded in 1864. Its clubhouse and boat house are located on the edge of the northern Beira Lake, at Sir Chittapalam A. Gardiner Mawatha (formerly Parsons Road), in Colombo. Since its inception the Colombo Rowing Club has progressed into one of the most prestigious and active private member clubs in Sri Lanka. A distinctive feature has been that while the club's main sporting focus remains in rowing, social interaction and fellowship is also an important aspect. The club claims to be the ''cradle of rowing in Sri Lanka'' since most affiliated clubs of the Amateur Rowing Association of Sri Lanka, governing body for rowing in Sri Lanka, started from the facilities and infrastructure that is available at the Colombo Rowing Club. History The club was founded on the July 15, 1864 by Sir Edward Creasy, the former Chief Justice of Ceylon and based on available records, the CRC claims to b ...

Gliricidia
''Gliricidia'' is a genus of flowering plants in the legume family, Fabaceae and tribe Robinieae. Its native range is Mexico to Peru, but ''Gliricidia sepium'' has been widely introduced to other tropical zones. The species ''G. sepium'' is a small, deciduous, ornamental tree, cultivated and used for a variety of purposes in tropical regions. The genus name ''Gliricidia'' means "mouse killer" in reference to the traditional use of the toxic seeds and bark of ''G. sepium'' as rodenticides. The tree is leafless when in flower and bears fruits during April and May in India and countries with same climate. The small flowers (barely 2 cm long) are pale pink and they are borne in dense clusters on bare twigs. Flowers fade to white or a faint purple with age. The flowers attract a lot of bees and some lycaenid butterflies—particularly the Peablue ''Lampides boeticus'' and other native birds. Species The following species are valid: *''Gliricidia brenningii'' (Harms) Lavin *''Gl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agroforestry
Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland. Trees produce a wide range of useful and marketable products from fruits/nuts, medicines, wood products, etc. This intentional combination of agriculture and forestry has multiple benefits, such as greatly enhanced yields from staple food crops, enhanced farmer livelihoods from income generation, increased biodiversity, improved soil structure and health, reduced erosion, and carbon sequestration. Agroforestry practices are highly beneficial in the tropics, especially in subsistence smallholdings in sub-Saharan Africa and have been found to be beneficial in Europe and the United States. Agroforestry shares principles with intercropping but can also involve much more complex multi-strata agroforests containing hundreds of species. Agroforestry can also utilise nitrogen-fixing plants such as legumes to restore soil nitrogen fertility. The nitrogen-fixing plant ...

Sustainable Agriculture
Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within sustainable food systems, it is important to develop flexible business process and farming practices. Agriculture has an enormous environmental footprint, playing a significant role in causing climate change ( food systems are responsible for one third of the anthropogenic GHG emissions), water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes. Sustainable agriculture consists of environment friendly methods of farming that allow the production of crops or livestock without damage to human or natural systems. It ...

Leaf Mulch
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of '' Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper ( adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs l ...

Soil Conservation
Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination. Slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. A sequel to deforestation is typically large-scale erosion, loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil. Code 330 defines standard methods recommended by the U.S. Natural Resources Conservation Service. Farmers have practiced soil conservation for millennia. In Europe, policies such as the Common Agricultural Policy are targeting the application of best management practices such as reduced tillage, winter cover crops, p ...
