What is the importance of irrigation and drainage?

Subsurface drainage systems are as important in many irrigated areas as they are in humid areas. A drainage system is needed on irrigated lands to control the water table and ensure that water will be able to move through a soil, thus keeping salts from accumulating in the root zone and making the soil unproductive.

What is the most common irrigation?

1. Surface Irrigation. It is the most common type of irrigation as it simply employs gravity to distribute water over a field by following the contour of the land. In surface irrigation, for example, water will flow downhill from an area of higher elevation, reaching all the crops.

What is the best method of irrigation for agriculture?

Sprinkler or drip irrigation are preferred above surface irrigation on steeper or unevenly sloping lands as they require little or no land levelling. An exception is rice grown on terraces on sloping lands. Climate: Strong wind can disturb the spraying of water from sprinklers.

What is the best type of irrigation system?

What are the two main types of drip irrigation?

Which is the best method of irrigation and why?

Drip irrigation is the most efficient and appropriate irrigation system. Instead of wetting the whole field surface, water is applied only to the plant root zone. The primary goal of drip irrigation is to apply water at the time when plants need it most and in rates needed for proper plant growth.

What are the two basic types of irrigation systems?

There are two main types of irrigation systems: low flow and high flow. Both can be utilized in one garden if needed. Low flow systems refer to micro spray, drip emitters, or drip lines. High flow systems are fixed spray, rotor, impact, bubbler, and soaker hose.

What are the effects of over irrigation and poor drainage?

Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring watertable control by some form of subsurface land drainage.

What is the difference between irrigation and drainage?

Drainage refers to the removal of excess water from the ground surface as well as from the subsurface soil to facilitate the proper growth of plants and to avoid the hazards due to water logging. ... Irrigation refers to the application of controlled amounts of water to plants at needed intervals.

Why is irrigation so important?

In areas that have irregular precipitation, irrigation improves crop growth and quality. By allowing farmers to grow crops on a consistent schedule, irrigation also creates more reliable food supplies. ... Modern irrigation systems use reservoirs, tanks, and wells to supply water for crops.
