Impacts of Salt on Water Resources

In Iran and Pakistan, the salinization of land resources is a major problem due to a combination of primary salinity and secondary salinity (Kahlown et al., 2003; Qadir, Qureshi, & Cheraghi, 2008).Primary salinity in Iran is a result of a combination of factors including: the geological composition of the soil’s parent material, such as halite and gypsum, natural salinization of surface waters due to stream salinity, salinity and the expansion of salinity from wind-borne origins, seawater intrusion, low rainfall and high potential evapotranspiration (Qadir, Qureshi, & Cheraghi, 2008).Dryland salinity, a form of secondary salinity, has particularly become a major problem worldwide (Beresford et al., 2001).In Australia, areas of th...

Impact of Waterlogging on Plants

”Waterlogging is a major problem restricting the plant growth by leading to oxygen deficiency around roots and rhizomes, and consequently it can be fatal because aerobic respiration ceases and levels of energy-rich adenylates drop rapidly resulting in dramatic decrease in ion uptake and transport” (Huang et al, 2003; vartapetian et al, 2003) as quoted in (Changdee., et al, 2008).Then it focuses on five plant species of global interest or importance, Barley, Tomatoes, Soy Bean, Cotton and Rice, showing the effect of waterlogging on each, quoting journals and experiments done by fellow scientist .The topic of research into waterlogging is vast, with thousands of journals and experiments on countless plant species, so I’m focusing on just f...

The Relevance of Mangroves in Climate Change Essay

The biggest problem mangroves face is nutrient uptake.Taxonomy and evolution .[4] The saline conditions tolerated by various mangrove species range from brackish water, through pure seawater (30 to 40 ppt), to water concentrated by evaporation to over twice the salinity of ocean seawater (up to 90 ppt).The return of tide can flush out these soils, bringing them back to salinity levels comparable to that of seawater.The following listing (modified from Tomlinson, 1986) gives the number of species of mangroves in each listed plant genus and family.

Woodlands & forests Essay

An article in New Scientist magazine shows that new climate models have found that forests help cool the atmosphere as the water evaporating from leaves absorbs heat, it also stated that the location chosen to afforest is important as if you chose to plant a forest to take in C0 2 it could actually lead to warming if it was planted in a region where snow falls, as this would change the lands albedo value and would reflect less sunlight.It also affects salinity by transpiring water it helps keep the water table well below the surface and prevents salinisation from occurring.Afforestation will affect the water cycle in a positive way by helping areas with low rainfall have more precipitation for its local crops etc.It also influences the h...

Waterlogging of Soil

Currently Victoria has 1.8 million ha affected by waterlogging.Waterlogging is the lower in land productivity through the rise in groundwater close to the soil surface, and also where the water table rises above the surface.·     Nitrogen deficiency.Waterlogging occurs mostly on flat floodplain areas or gently sloping landforms with high rainfall and red duplex or heavy clay soils.Farmers need to manage and plan their irrigations properly, so that they do not over water the soil.

Comparison of Normal Saline and Heparin Flush

Floor nurses were used as observers and observe catheter failures, as either loss of patency or phlebitis.More catheters flushed with heparin were removed because of problems (p = .027).The researcher concluded that heparin was shown to cause more phlebitis than saline (p < 0.025), but no difference was found between the two flushing solutions in loss of patency.Quality of care can be enhanced by using saline as the flush solution, thereby eliminating problems associated with anticoagulant effects and drug incompatibilities.In addition, an estimated yearly savings of $109,100,000 to $218,200,000 U.S. health care dollars could be attained.

Impact of Agriculture Credit on Agriculture Productivity

Pest problems have shown marked increase in changing agriculture.Pest problems have increased with the intensification of agriculture.Emphasis in the 1980s and early 1990s was on rehabilitation and preservation of existing canals and watercourses, on farm improvements on the farms themselves (including some land leveling to conserve water), and on drainage and salinity in priority areas.Nevertheless, serious problems in the design of the irrigation system avert achieving the highest potential agricultural output.However, by 1978 (when the Indus Basin Salinity Survey was completed), the water table in 22% of the Indus Basin was within 1.8 m of the surface, and an additional 30% was within 3 m. The condition has get worse since then.

The soil type

The productivity of oak trees and vegetation in general is dependant on soil type.This investigation would benefit from using a larger sample size that would increase the validity of the results.An extension could be carried out and the east facing hillside could be sampled at different times of year to see how vegetation and soil properties may vary.On the day of data collection it was raining heavily and some rainwater may have contaminated the test tubes affecting the pH values.The catena concept looks at individual sections of the hillside as open systems with inputs, throughputs and outputs that determine the soil types found there.

Salinity Responsiveness in Finger Millet Analysis

Seeds of two contrasting genotypes of rice ( ) {FL478 (tolerant), White Ponni (Susceptible)} and finger millet ( ) {Trichy 1 (tolerant), CO12 (Susceptible)} in terms of salinity tolerance were evaluated for their responses against salinity stress under greenhouse conditions.But much more concerted efforts are needed to identify and exploit diverse crop species exhibiting superior level of salinity tolerance which will help in identifying novel genes associated with salinity tolerance.Gas exchange parameters were recorded in the third leaf (from top) of control and salinity stressed plants of rice and finger millet genotypes between 1000 hours and 1200 noon at 11 DAS (days after stress) using LI-COR 6400-XT photosynthesis system (LI-COR...

Salinity in Rice Production

Several salt-induced proteins have been identified in plant species and have been classified into two distinct groups such as (i) salt stress proteins, which accumulate only due to salt stress and (ii) stress associated proteins, which also accumulate in response to heat, cold, drought, water-logging and high and low mineral nutrients (Pareek et al., 1997; Ali et al., 1999; Mansour, 2000).Amino acids have been reported to have accumulated in higher plants under salinity stress (Ashraf, 1994b; Mansour, 2000).In addition to the development of salt tolerant cultivars, better understanding of nutritional disorders in the context of plant nutrient uptake and physiological as well as biochemical mechanisms of salt tolerance in rice plants may ...

Benefits Of Using Halophytes Environmental Sciences Essay

As such, halophytes can be grown in saline areas in which traditional crops falter, as well as in regions increasingly affected by dryland salinity.In Western Australia alone, 6.5 million hectares of agricultural land are at risk of dryland salinity due to land degradation (ANRA, 2002), and traditional crops such as wheat and canola will then be unproductive to be farmed.Studies have shown that it is able to grow and reproduce at salinity levels of up to 300 mM NaCl, and can be grown at levels up to 100 mM NaCl without losing its nutritional values (Ladeiro, 1997).Environmental stresses such as salinity affects solute transport in plants and can cause changes in the partitioning of carbon and nitrogen.When grown in highly saline environm...

Geography Erosional Landforms

Small-scale, active landforms include lobes and sheets and turf-banked terraces.The latter reflect also the action of wind in stripping and shaping the vegetation mat and frequently occur in association with deflation surface.This land form is also not currently used for anything and will increase because: more ice melting means more waterlogged soil which means more solifluction lobes.Solifluction adds detail to the terrain underfoot.Pingo = Open-system pingos form when groundwater moves from a distant, elevated source under hydraulic pressure.
