Tecticornia Lylei
''Tecticornia lylei'', commonly known as wiry glasswort, is a small shrub with in the family Chenopodiaceae. It occurs in saline clay soils on the beds of and around the perimeter of salt lakes. The erect shrub can grow up to 1 m in height and 1.5 m wide, and has slender branches with very slender branchlets, its articles cylindrical, dull mid-green and about 3 mm long and 2 mm wide. The wiry glasswort flowers between November and June, with tiny flowers less than 3 mm across which fruit when pollinated. Listed as endangered in New South Wales and rare in Victoria and South Australia, ''T. lylei'' is threatened by trampling and overgrazing, vegetation clearing and stochastic events. Distribution and habitat ''Tecticornia lylei'' is an endangered species in NSW and rare in Victoria, with the numbers especially low in the once plentiful low open-shrubland in the Murray Darling Depression Bioregion. Requiring particularly saline soils to survive, it occurs on saline clay soils ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chenopodiaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterlogging (agriculture)
Waterlogging water is the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. In extreme cases of prolonged waterlogging, anaerobiosis occurs, the roots of mesophytes suffer, and the subsurface reducing atmosphere leads to such processes as denitrification, methanogenesis, and the reduction of iron and manganese oxides. All plants, including crops require air (specifically, oxygen) to respire, produce energy and keep their cells alive. In agriculture, waterlogging of the soil typically blocks air from getting in to the roots. With the exception of rice (''Oryza sativa''), most crops like maize and potato, are therefore highly intolerant to waterlogging. Plant cells use a variety of signals such the oxygen concentration, plant hormones like ethylene, energy and sugar status to acclimate to waterlogging-induced oxygen deprivation. In ...

Forage Harvester
A forage harvesteralso known as a silage harvester, forager or chopperis a farm implement that harvests forage plants to make silage. Silage is grass, corn or hay, which has been chopped into small pieces, and compacted together in a storage silo, silage bunker, or in silage bags. It is then fermented to provide feed for livestock. Haylage is a similar process to silage but using grass which has dried. Uses Forage harvesters can be implements attached to a tractor, or they can be self-propelled units. In either configuration, they comprise a drum (cutterhead) or a flywheel with a number of knives fixed to it that chops and blows the silage out of a chute of the harvester into a wagon that is either connected to the harvester or to another vehicle driving alongside. Towed harvesters are either single-chop, double-chop or precision-chop. Most larger machines also have paddle accelerators to increase material speed and improve unloading characteristics. Older machines were operated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubestock
Tubestock is the plural term for young plants which have been grown to the point where they are ready for either planting out in the field or potting on to larger pot sizes. Smaller, shallower pots (approx. 50mm in diameter x 80mm deep) are usually used to grow Tubestock in for the purpose of them being potted on to larger sizes. Larger, deeper pots (approx. 50mm square x 120mm deep) are generally preferred for planting out in the field, as in the case of Revegetation and Landscaping. The term tubestock generally refers to seedlings grown in individual pots (or Tubes) as opposed to smaller seedlings grown in cell-trays containing from 100 to 500 plants, which are referred to as "Plugs".

South Australia Department For Environment And Water
The Department for Environment and Water (DEW) is a department of the Government of South Australia. Created on 1 July 2012 by the merger of the Department of Environment and Natural Resources and the Department for Water as the Department of Environment, Water and Natural Resources (DEWNR), it was given its present name on 22 March 2018. It is responsible for ensuring that South Australia's natural resources are managed productively and sustainably, while improving the condition and resilience of the state's natural environment. Origins History of the environment portfolio in South Australia #On 23 December 1971, a new department called the ''Department of Environment and Conservation'' was created by the amalgamation of the ''Museum Department'' and the ''State Planning Office'' which was part of the ''Department of the Premier and of Development''. #On 18 December 1975, the ''Department of Environment and Conservation'' was renamed as the ''Department for the Environment' ...
