You will receive a link and will create a new password via email. The main types of irrigation are briefly explained in this article. Micro-irrigation is an irrigation method that applies water slowly to the roots of plants, by depositing the water either on the soil surface or directly to the root zone, through a network of valves, pipes, tubing, and emitters. If you use irrigation water, you will purchase water on a seasonal basis. Water management is the management of water resources under set policies and regulations. An irrigation pump is used for providing water to a section of land. One of these methods is called surface irrigation, in which the farmer disperses water over the land by either flooding it or running it down furrows, which are lanes in the field. It also applies to maintaining landscaping features, such as turf/grass, trees, shrubs, and flowers. Irrigation takes the place of rainfall in dry regions. This makes the soil completely saturated. Irrigation and drainage, artificial application of water to land and artificial removal of excess water from land, respectively. Mobile drip irrigation (MDI) combines the high efficiency of surface drip irrigation with the flexibility, lower hardware costs, and convenience of center pivot irrigation. Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops. It works by exposing the roots to a direct supply of water. Letting water drop onto plants through holes in pipes, known as drip irrigation, is considered one of the most efficient methods of irrigation.

In certain areas, small ditches are made in different locations of the irrigation land, so that water from the ditches may percolate and nourish the crops, which also is a method of sub-surface irrigation system. This irrigation type is very costly and employed for crops that provide high returns and profit. The irrigation water need is defined as the crop water need minus the effective rainfall. Roots of the plants do not grow well in dry soil. It usually will be used for more extensive properties that need a system to help manage the volume, rate, and timing of water application in order to match with water holding capacities and soil intake. The trickle or drip method uses an underground system of pipes to water plants directly and is one of the most water-efficient methods. While the basic concept of irrigation is a simple one, there are many fascinating and remarkable systems in use today. For example, the physical and mechanical properties of the soil, ex.
