Do farmers use irrigation?

Why is irrigation still important today?
Irrigation, one of the many important aspects in feeding the world, allows farmers and producers to control the amount of water that is placed on the field which allows the crop to get the needed amount of water for growth and development; essentially creating a higher yield.
What percent of farmers use irrigation?
The U.S. Geological Survey (USGS), which monitors water use by economic sector, estimates that irrigated agriculture accounted for 38 percent of the Nation’s freshwater withdrawals in 2010. Agriculture, however, accounts for approximately 80 to 90 percent of U.S. consumptive water use.
What is the best time to irrigate?
The best time of day to begin irrigation is after nightfall. The irrigation cycle should end early enough before sunrise to allow excess water to soak into the landscape so that the leaves will dry in the normal time period.

Excessive Water Absorption Due to the hypotonicity, absorption of Sterile Water for Irrigation can result in serious adverse reactions of hyponatremia, hypoosmolality and fluid overload, resulting in fatality or permanent morbidity.
What is modern method of irrigation?
The modern methods of irrigation include sprinkler systems, drip systems, etc. In the sprinkler system, water is sprinkled on the crop by using a pipe and nozzle system. It resembles raining. In the drip system, waterfalls drop by drop just at the position of the root.
What are positive and negative effects of irrigation?
The effects may be water mining, land/soil subsidence, and, along the coast, saltwater intrusion. Irrigation projects can have large benefits, but the negative side effects are often overlooked. The lower the irrigation efficiency, the higher are the losses.
