Irrigation and its methods

It was likely the first form of irrigation used by humans as they began cultivating crops and is still one of the most commonly used methods of irrigation used today. With flood irrigation it is generally assumed that only half of the water applied actually ends up irrigating the crop [1].

The other half is lost to evaporation, runoff, infiltration of uncultivated areas, and transpiration through the leaves of weeds. Although flood irrigation will never be as efficient as other types of irrigation there are several techniques that can be used to improve its efficiency: Recycling runoff — water that runs off the end and sides of the irrigated are is captured in low-lying areas and pumped to the top of the field where it can be reused.

It is common for flood irrigators to release water until the entire field is covered. By flooding the entire field all at once, irrigators fail to take advantage of capillary movement of water through the soil, particularly in clay soils.

This results in significant runoff, anaerobic conditions in the soil and around the root zone, and deep irrigation below the root zone that is unavailable to the plants. Soil moisture sensors provide irrigators with a useful tool when used in conjunction with surge irrigation also known as cut-off irrigation [2].

Irrigation and its methods

Strategic placement of sensors near the end of the irrigated area and at selected depths alert the irrigator when the soil is saturated and irrigation should be cut off to take advantage of the infiltration that occurs.

Flood Irrigation Introduction. Flood irrigation is an ancient method of irrigating crops. It was likely the first form of irrigation used by humans as they began cultivating crops and is still one of the most commonly used methods of irrigation used today.

Successful farmers have used different methods to apply water to their crops. production. In traditional agriculture, irrigation was. You've found the web's mother lode of irrigation information!

To choose an irrigation method, the farmer must know the advantages and disadvantages of the various methods. He or she must know which method suits the local conditions best.

Unfortunately, in many cases there is no single best solution: all methods have their advantages and disadvantages. Testing. Read this article to learn about the important methods of irrigation, i.e., (1) Surface Irrigation (2) Overhead or Sprinkler Irrigation (3) Drip or Trickle Irrigation.

In this method water flows and spreads over the surface of the land. Varied quantities of water are allowed on the fields at.

Pressurized Distribution

Systems of pressurised irrigation, sprinkler or drip, can improve water efficiency and contribute substantially to improved food production.

Sprinkler irrigation is a type of pressurised irrigation that consists of applying water to the soil surface using mechanical and hydraulic devices that simulate natural rainfall (see Figure 1).
