Tamarix
The genus ''Tamarix'' (tamarisk, salt cedar, taray) is composed of about 50–60 species of flowering plants in the family Tamaricaceae, native to drier areas of Eurasia and Africa. The generic name originated in Latin and may refer to the Tamaris River in Hispania Tarraconensis (Spain). Description They are evergreen or deciduous shrubs or trees growing to in height and forming dense thickets. The largest, ''Tamarix aphylla'', is an evergreen tree that can grow to tall. They usually grow on saline soils, tolerating up to 15,000 ppm soluble salt, and can also tolerate alkaline conditions. Tamarisks are characterized by slender branches and grey-green foliage. The bark of young branches is smooth and reddish brown. As the plants age, the bark becomes gray-brown, ridged and furrowed. The leaves are scale-like, almost like that of junipers, long, and overlap each other along the stem. They are often encrusted with salt secretions. The pink to white flowers appear in dense ...

Aeroponics
Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the ancient Greek: ''aer'' (air) and ''ponos'' (labor, hardship, or toil). It falls under the category of hydroponics, as water is employed in aeroponics to deliver nutrients to the plants. Methods The fundamental principle of aeroponic growing entails suspending plants in a closed or semi-closed environment whilst spraying their dangling roots and lower stems with a nutrient-rich water solution in an atomized or sprayed form.Stoner, R.J. and J.M. Clawson (1997-1998). ''A High Performance, Gravity Insensitive, Enclosed Aeroponic System for Food Production in Space.'' Principal Investigator, NASA SBIR NAS10-98030. The upper portion of the plant, including the leaves and crown, referred to as the canopy, extends above. The plant support structure keeps the roots separated. To minimize labor and expenses ...

Desert
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or Semi-arid climate, semi-arid. This includes much of the Polar regions of Earth, polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night strain the Rock (geology), rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting frag ...

Shade Tree
A shade tree is a large tree whose primary role is to provide shade in the surrounding environment due to its spreading canopy and crown, where it may give shelter from sunlight in the heat of the summer for people who seek recreational needs in urban parks and house yards, and thus, also protecting them from the sun's harmful UV rays. Some of the most popular shade trees in temperate countries are oaks, plane trees, willows, birches, beeches, maples, ashes, lindens, and elms. In subtropical countries like Australia and India, figs are popular choices as shade trees. In tropical countries, trees such as some ''Erythrina'' and African tulip tree species are often planted as shade trees. Specialities These trees are commonly grown, and/or used, as shade trees due to their protuberant size: * American elm * American sycamore * Austrian oak * Brush box * Banyan tree * Black walnut * Blue Jacaranda * Camphor laurel * Cape Chestnut * Carob tree * Chinese elm * Coas ...

Field (agriculture)
In agriculture, a field is an area of land, enclosed or otherwise, used for agricultural purposes such as cultivating crops or as a paddock or other enclosure for livestock. A field may also be an area left to lie fallow or as arable land. Many farms have a field border, usually composed of a strip of shrubs and vegetation, used to provide food and cover necessary for the survival of wildlife. It has been found that these borders may lead to an increased variety of animals and plants in the area, but also in some cases a decreased yield of crops. Paddock In Australian English, Australian and New Zealand English, any agricultural field may be called a ''paddock'', especially if for keeping sheep or cattle. If stock are grazed there, the space may be called a ''run'', e.g. ''sheep run''; ''cattle run''. The term paddock is used more specifically in animal husbandry for a system in which grazing land is divided into small areas, paddocks, and the stock graze each paddock in tur ...

Windbreak
A windbreak (shelterbelt) is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted in hedgerows around the edges of fields on farms. If designed properly, windbreaks around a home can reduce the cost of heating and cooling and save energy. Windbreaks are also planted to help keep snow from drifting onto roadways or yards. Farmers sometimes use windbreaks to keep snow drifts on farm land that will provide water when the snow melts in the spring. Other benefits include contributing to a microclimate around crops (with slightly less drying and chilling at night), providing habitat for wildlife, and, in some regions, providing wood if the trees are harvested. Windbreaks and intercropping can be combined in a farming practice referred to as alley cropping, or being deployed along riparian buffer stripes. Fields are planted in rows of different cro ...

Eucalyptus
''Eucalyptus'' () is a genus of more than 700 species of flowering plants in the family Myrtaceae. Most species of ''Eucalyptus'' are trees, often Mallee (habit), mallees, and a few are shrubs. Along with several other genera in the tribe Eucalypteae, including ''Corymbia'' and ''Angophora'', they are commonly known as eucalypts or "gum trees". Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard, or stringy and leaves that have oil Gland (botany), glands. The sepals and petals are fused to form a "cap" or Operculum (botany), operculum over the stamens, hence the name from Greek ''eû'' ("well") and ''kaluptós'' ("covered"). The fruit is a woody Capsule (botany), capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are Indigenous (ecology), native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Many eucalypt species have adapted to wildfire, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Plant
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. A wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. A native species in a location is not necessarily also endemic to that location. Endemic species are ''exclusively'' found in a particular place. A native species may occur in areas other than the one under consideration. The terms endemic and native also do not imply that an organism necessarily first originated or evolved where it is currently found. Notion The notion ...
