Humanity throughout the years have endeavored to increase production of arable farmland to maintain the ability to feed the ever increasing population. Irrigation is generally considered the most effective way of increasing farmland production. It can help supplement the water needed for crop growth when rainfall is at a low point or, in more humid areas, it can help bridge dryer times and reduce agricultural risks. The goal of irrigating is to increase the land usable for crops, the crop production per harvest per season, and the diversity of crops that can be grown in different areas(R.J. Oosterbaan, Page 1). With the advent of irrigation leads to the problem of waterlogging. In flat lands, waterlogging is the result of local losses of irrigation water, due to
leakage from canals and above all from percolation in irrigated fields from the absence of
sufficient natural drainage capacity of the aquifer. These waters further add to the groundwater
reservoir, thereby raising the water table. In lands with considerable differences in topography, waterlogging occurs primarily in depressions, valley floors, or at the foot of slopes. It is caused by the flow of groundwater from irrigation losses in higher-lying areas.
Salinity develops in arid and semi arid regions, simultaneously with waterlogging. As long as the water table remains deep, the salts, imported with the irrigation water, are washed down into the deeper soils with the percolation losses of irrigation water. If the water table becomes more shallow however, excess irrigation can no longer take place, otherwise the land would become flooded with stagnating water. At this point, salt leaching no longer occurs, and the salts brought in with the irrigation water accumulate i...

... animal consumption, animals consuming salty water can have many health problems. As an example, dry cows need
about 8 to 10 gallons of water daily. Cows in their last 3 months of pregnancy may drink up to 15 gallons a day. Those in milk need about five times as much water as the volume of milk produced. And calves require much more water after weaning than before.
Despite the many disappointing results, irrigation can and will need to be a central component in producing food for the world’s growing population and in sustaining the livelihood of farmers. In the past many positive examples have been created. It is therefore vital that engineers and economists rehabilitate the reputation of irrigation by embarking on more effective irrigation projects in which they give due attention to environmental impacts that may change an environment permanently in the future.

Essay Waterlogging of Soil

- What is it. 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. The raised water table results in the soils becoming waterlogged and air spaces in the soil are filled with water, and plant roots, in effect, suffocate from the lack of oxygen, limiting plant growth in those areas. Where does it occur. Waterlogging occurs where bad irrigation methods are used and in poorly drained soils where water can't penetrate deeply....   [tags: Environmental, Informative, ]

Essay on A Brief Note On Agriculture And Agriculture Practices

- Introduction Although people are becoming aware of the significance of land protection, the amount of arable land is still decreasing at an alarming rate. More specifically, according to a study cited by UNCCD, the United Nations Convention to Combat Desertification, the land degradation costs about $490 billion per year. However, if sustainable actions are taken, there will be $1.4 trillion increase in crop production. Therefore, in order to mitigating the loss of arable land due to modern U.S....   [tags: Agriculture, Irrigation, Soil, Water]

Salinization Essay

- Salinization has been a problem for cultivators since humans were able to live a more sedentary lifestyle. Salinization occurs when too much water-soluable salts are introduced to soil or water systems (Kaushal). The causes of salinization vary greatly depending on the region, and water delivery systems. It can occur naturally or by faulty management of soils and water. Once a soil or water source is salinized, it can cause great stress on the surrounding environment. Salinization of an environment has social, ecological, and economic impacts (“Impacts of Salinity”)....   [tags: Irrigation, Mesopotamia, Agriculture, Water]

Essay on Irrigation As A Common Irrigation Method

- Irrigation has been around for as long as humans have been cultivating plants. Man 's first invention after he learned how to grow plants from seeds was probably a bucket. Ancient people must have been strong from having to haul buckets full of water to pour on their first plants. Pouring water on fields is still a common irrigation method today -- but other, more efficient and mechanized methods are also used. Flood (furrow) irrigation: Early man would have used this "low-tech" method of irrigating crops -- collect water in a bucket and pour it onto the fields....   [tags: Water, Irrigation, Agriculture, Hydrology]

Essay on Waterlogging and Plants

- Growth and development of plants are severely influenced by the stagnant waterlogged condition. Plants grown on arable farmland or watery environment show differential responsiveness to the stress. The level of variation in response to waterlogging is a critical issue regulating abundance and distribution of plants [1]. Rice (Oryza sativa L.) is particularly tolerant to submergence, whereas tomato (Solanum lycopersicon L.) is highly intolerant [2]. Within species, Mentha arvensis is more tolerant than Mentha piperita [3]....   [tags: Hypoxia, Genes]

Essay on The Urban Revolution And Irrigation Were On The Rise

- In 6000 BC farming and irrigation were on the rise. Since there was little rain in Southern Mesopotamia they created irrigation which lead farmers to settle in Southern Mesopotamia. With the large increase in population in Southern Mesopotamia, things quickly changed. There were new inventions and ideas, which led to the exchange of those inventions and ideas- known as trade. Over hundreds of years farmers and inhabitants settled along the Tigris and Euphrates River banks and plains. Some of the villages were religious and will later evolve into Sumerian city states....   [tags: Sumer, Mesopotamia, Sargon of Akkad, Uruk]

Essay on Seawater Irrigation Is Solution To Water Shortages

- “Agriculture is a major user of ground and surface water in the United States, accounting for 80% of the Nation's consumptive water use and over 90% in many Western States” (“Irrigation and Water Use”). As population grows, our demand for food and agriculture also grows. Therefore, we need a more efficient irrigation system. In “U.S. to tighten tap for farmers”, Bloomekatz mentioned that the government had reduced or even refused to supply water to some agriculture fields in 2009. In Central Valley, the government had refused to provide water for over 200 water districts....   [tags: Drinking Water Scarcity]

Irrigation as a Tool for Frost and Freeze Protection Essay

- For years now farmers and researchers have understood the value of applying water to crops during periods when the temperature drops below 32oF (0oC). The temperature of 32oF is the freezing point of water and is the temperature at which crops start to become damaged due to the formation of ice crystals in their tissue cells. The point that this starts to occur is considered the crops critical temperature. The critical temperature usually is slightly lower than the freezing point of water and depends on the duration at the temperature....   [tags: Agriculture Crops Farming Papers]

Essay Nitrogen and Irrigation on Coastal Plains Soils

- Nitrogen and Irrigation on Coastal Plains Soils So why is it important to look at nitrogen in soils. First of all, it is a key element in organic molecules, so it is key to plant growth (Singer and Munns). Nitrogen is useful to plants in the form of nitrate because plants can take in nitrate and form organic molecules (Singer and Munns, 193). However, in soils, nitrogen in the form of nitrate (NO3) is considered a "mobile nutrient" which means that it can move easily through the soil to supply the needs of a plant (Singer and Munns, 221)....   [tags: Agricultural Agriculture Farming Essays]
