J Environ Sci Health A38:185–200, Taylor SA (1952) Use of mean soil moisture tension to evaluate the effect of soil moisture on crop yields. Water retention. Water is a precious natural resource, and freshwater is scarce too. Bulk density / porosity. These soil properties are essential to crop production. Porosity. agricultural water is extremely important and will become increasingly so, as fresh water supplies for irrigation become more scarce. It will enable the reader to scientifically analyze soils to develop practical and successful means of providing sufficient drainage and to develop science-based irrigation strategies. Surface irrigation is used on 85% of the irrigated land in the world. Irrigation is defined as the artificial application of water to the soil for the purpose of crop production in supplement to rainfall and ground water contribution. Cite as. The influence of texture on soil properties. Ann Appl Biol 146:239–259, Richards LA (1954) Diagnosis and improvement of saline and alkali soils. In this region, shallow water tables causing spring planting delays and excess water conditions during the growing season, may have contributed to significant unplanted cropland and yield reductions in recent years. Drainage, in agriculture, the artificial removal of water from land; drainage is employed in the reclamation of wetlands, in the prevention of erosion, and as a concomitant of irrigation in the agriculture of arid regions. Spell. Hydraulic conductivity / drainage. Academic, San Diego, O’Kane JP, Pokrovskii A, Flynn D (2004) The fest model for testing the importance of hysteresis in hydrology. This process is experimental and the keywords may be updated as the learning algorithm improves.

These same properties also influence related activities such as tillage, erosion, drainage, and irrigation. Publications. Ann Appl Biol 147:211–226, Radcliffe DE, Rasmussen TC (2002) Soil water movement. In Module 1, the need for drainage, the drainage methods and the design approaches for agricultural drainage systems are introduced. Drainage also reduces or eliminates mildew infections and various root rots of plants. So, water—soil water or irrigation water—need cautious management. Pages: 501-970. Journal of Architectural Engineering Technology, Journal of Civil & Environmental Engineering. Yields of many crops are reduced significantly due to water stress. In general, with appropriate irrigation management, there is increased growth, reduced production times, a more efficient use of fertilizers and pesticides, and reduced water and nutrient losses water science researchers and irrigation experts is important more than ever. Irrigation has been a central feature of agriculture for over 5000 years, and was the basis of the economy and society of numerous societies, ranging from Asia to Arizona. USDA, Washington, DC, Chakraborti D, Rahman MM, Paul K, Chowdhury UK, Sengupta MK, Lodh D, Chanda CR, Saha KC, Mukherjee SC (2002) Arsenic calamity in the Indian subcontinent: what lessons have been learned? With all the rain we received this winter, it is also important to make sure that your beds drain properly as you water them. Write. 38. 96). Why do we need to pay attention to drainage? Soil Science Society of America, Madison, Southorn N (1997) Farm irrigation: planning and management. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growth in grain fields and preventing soil consolidation. Publication of this supplement was supported by Chinese National Committee on Irrigation and Drainage (CNCID). Importance of water to plants. 1997; Kilic 2009).

The three main methods of irrigation are surface, sprinkler and micro. Adequate irrigation management remains an important factor for many crops, as any water application excess leads to energy waste. During heavy rainfall the upper soil layers become saturated and pools may form. Irrigation - Time and methods Modern techniques of - - Drainage and its irrigation importance . Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Poorly drained and badly aerated soils occur in many parts of the world with an estimated 12% of the world soils having excess water. Drainage is regarded as an important water management practice, and as a component of efficient crop production systems. Terms in this set (28) Border-strip irrigation. Irrigation is the process through which controlled amount of water can be supplied through artificial means such as pipes, ditches, sprinklers etc. Therefore, optimal management of soil and water salinity in saline-sodic soils should be regarded as an important factor in sustainable agriculture.
