    University of Bahrain College of science Department of biology The Effect of Salinity on Seed Germination 1) Abstract: Poor seeding growth can be the result of soil salinity. A study was done to examine the influence of NaCl salinity treatment on the germination and seeding grow of vigna radiata using different NaCl concentration 0 (control) ‚ 0.25 ‚ 0.5 ‚ 1.0 ‚ 1.75 . A graph was used to analyze the data obtained from the study. Important differences among the treatment

    Irrigating Crops with Seawater Brown J. Jed‚ Glenn Edward P.‚ and O’Leary James W. 1998. Irrigating Crops with Seawater. Scientific American. “Irrigating Crops with Seawater” talks about the global problem of finding enough water and land for the world’s population to survive. An estimated 494.2 million acres of cropland is needed just to feed the tropics and subtropics for the next 30 years. However‚ only close to 200 million acres are available

    assignment is seawater obtained from the hydrosphere. The seawater can be separated through out several processes‚ both chemically and physically. The separation process is known as desalination. This name is getting more common everyday‚ as the Australian water demand grows with population we can no longer ignore the salinity problem. Desalination process could take use of the salt concentrated water‚ turning them into fresh water. Industrial Separation Procedure: 1. The seawater is inputted through

    do you think is the cause of the “dip” (i.e.‚ decrease) in salinity around the equator? Could it not be argued that higher temperature causes more evaporation from the ocean surface‚ which‚ in turn‚ results in higher salinity content? Figure 9.4 shows how the surface temperature of the ocean and the surface salinity change with latitudinal position. Salinity the measure of the concentration of dissolved salts in the ocean water. Salinity influences where plants and animals can thrive‚ and also

    500 million ha under dry land agriculture‚ 32 million are salt-affected to varying degrees (2.1 percent) (Rengasamy‚ 2002). Careful monitoring of soil salinization is needed to reduce degradation and protect sustainable land use and management. Salinity is a natural process that occurs when dissolved salts accumulate in soil water‚ this affects plant growth and a way to monitor soil degradation with emphasis on salinization is through the use of remote sensing techniques. Remote sensing with technological

    Salinity is the measure and concentration of all the salts dissolved in water. Usually measured in parts per thousand (ppt or )‚ ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less (University of Rhode Island). Many factors go into salinity‚ making water salty. To name a few‚ salinity affects the environment through sediment from rocks washes into the ocean‚ evaporation of ocean water‚ and sea ice formation are known to increase the salinity of the ocean (NASA). It

    This might confuse predators. • gills for gas exchange. The rock pools provide a micro-climate where the temperature and salinity of the water will change‚ depending on the weather. If it was a really hot day‚ the rock pools will get warmer‚ more water will evaporate and the salinity will increase. The crab would have to be adapted to cope with these changes in salinity‚ otherwise‚ as the concentration of salt in the water around it changes‚ it will gain or loose mass due to osmosis. Through

    water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation‚ or decreased by the addition of fresh water by precipitation or runoff. Normally‚ in tropical regions where the sun is very strong‚ the ocean salinity is somewhat higher than it is in other parts of the world where there is

    Vicente Zarate Professor Foster English 100 November 21‚ 2013 “Desalination of Seawater” Water is extremely essential to every human in this world. The scarcity of water has increased in the past decades due to the overpopulation of humans. Today‚ we found ourselves in a critical stage where most people have not realized the consequences for the future generations. The government is investing economic resources to find innovative methods to produce fresh water. The process that removes salt
