Major Purposes and Types of Irrigation.
The process through which water is applied to plants through controlled amounts is referred as irrigation. Irrigation is done in intervals to ensure proper distribution and non-wasteful use of water. In areas where rain water is not sufficient, irrigation is the common option of growing plants. Landscape maintenance is another use of irrigation apart from growing agricultural products.
Growth of weed can be minimized through irrigation. The improper hardness of the soil can be eliminated through irrigation and hence ensure that the soil is efficient for growing plants. Animal production is also a major user of irrigation since it enables the cooling of animal bodies through drinking of water. Irrigation helps reduce and control dust. Irrigation in mining can be done to soften the rocks and also reduce the dust in the mining areas. Sewage disposal is the role played by irrigation. The removal of water where it is not supposed to be can be regarded as drainage which can be wholly defined as a way of irrigation.
Irrigation has been used in many countries throughout the world in different social cultures and hence different ways of usage. Irrigation in all countries using irrigation is geared towards ensuring continuous crop production and hence the country is able to sustain its citizens through sufficient food security. Irrigation has been greatly used in desert and semi-desert countries throughout a large period of time. The practice of irrigation have also developed throughout the ages due to the rise in irrigation technology. Water is being supplied to the dry areas of different countries through the proper utility and exploitation of the water bodies available in the country.
The types of irrigation depends on the method of water supply to the crops. The amount of water supplied to plants is dependent on the water consumption needs of the plant. Some plants vary in the consumption level including plants that entirely require water for growth like rice and sugarcane. Surface irrigation is one form of irrigation and it is regarded as one of the earliest and oldest mode of irrigation. This type of irrigation involves use of furrows and through this structure water flows throughout the cultivated land. This mode of irrigation causes flooding especially when the soil is saturated enough. Surface irrigation is common in areas or countries with ample water supply from the water bodies.
Another famous mode of irrigation is the micro irrigation which can also be referred as the trickle irrigation. There is the use of pipes and water is distributed in low amounts at a certain pattern. Drip type of irrigation involves low amounts of water which are commonly drops being applied to crops through sprinklers and sprays. Irrigation strategies are well initiated in destinations like the irrigation in Yakima.
