However, depending on field location and field size, it may not be possible to use water from these sources for irrigation.


How does water quality affect food?

Water quality can be affected by poor planning of industrial sites, animal farms, and barnyards and feedlots. Until recently, the type of water source has been indicative of the potential risks of contamination. Poor water quality can affect the quality of food crops and lead to illness in those who consume them. For example, the water may contain germs that cause human disease. Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. Groundwater, for example, has been considered one of the safest sources of water. However, depending on field location and field size, it may not be possible to use water from these sources for irrigation.

Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination.


Which type of irrigation system is most effective in areas with high water tables?

This system tends to be less expensive but requires more labor than others. Sub-irrigation. Water is distributed across land by raising the water table, through a system of pumping stations, canals, gates, and ditches. This type of irrigation is most effective in areas with high water tables. Manual irrigation.


How is water distributed in a field?

Water is distributed through a series of pipes, each with a wheel and a set of sprinklers, which are rotated either by hand or with a purpose-built mechanism. The sprinklers move a certain distance across the field and then need to have the water hose reconnected for the next distance.

How can farmers use water?

Through the process of drip irrigation farmers can supply water directly to the roots of their crops rather than sprinkling the water on top. Through properly installed drip irrigation systems, farmers can save up to 80% more water than standard sprinkler irrigation systems. Additionally, by creating ponds and reservoirs, farmers can draw their supply from there, taking the pressure off of local watersheds.

What is the importance of irrigation in agriculture?

Water applied as irrigation allows for crop production in arid regions and supplements soil moisture in humid regions when growing season precipitation is insufficient. Irrigation has enhanced both the productivity and profitability of the agricultural sector. According to the 2017 Census of Agriculture, farms with some form of irrigation accounted for more than 54 percent of the total value of U.S. crop sales, while irrigated land accounted for less than 20 percent of harvested cropland. Irrigated crop production helps to support local rural economies in many areas of the U.S., and contributes to the Nation’s livestock, food processing, transportation, and energy sectors.
