What environmental problem is the result of irrigation?
One of the main problems caused by irrigation is rising salinity. Irrigation salinity can be the result of several factors, such as over-irrigation of farmland or any practice that causes water to lie around for long periods. This leads to increased leakage to the groundwater system, which in turn causes the water table to rise. When the water table reaches to within 2 metres of e soil's surface, evaporation of the water can cause a buildup of salt which is already present in the soil to some degree.
What is the Ill effects of excess irrigation on soil?
Water loggingBreeding place of mosquitosGround water table is increasedComplete saturation of root zone causes efflorescence.
How does carrying irrigation water into fields through open ditches waste water?

What is natural subsurface irrigation and artificial subsurface irrigation?
natural subsurface irrigation :- those areas which lie near to canal and roots zone of crops doenst require irrigation water Artificial irrigation :- by a network of pipe and pump water is provide to the root zone
What effect does irrigation have on soil groundwater and rivers?
The effect irrigation has on soil is that it dampens it, making it better for growing crops. To groundwater, irrigation fills it up with water. Rivers are affected by irrigation by the irrigation flowing into it.
Did irrigation and household usage lead to a recent drop in water table levels Yes or No?
Yes.

How many different types of irrigation systems are there?
There are three types of irrigations methods. First is surface irrigation where the water is fed by simple gravity over a field such a rice paddy field. Sprinkler or drip irrigation is when water is delivered over the air onto the plants such as most fields in North America. Finally Sub-Irrigation where the water table to raise to the crop's roots level.
How does human activity impact ground water?
Over irrigation of growing crops could lower the water table in an area - especially in a desert environment.

How to do a work of the irrigation of the water or irrigation of drip?

What do you call it when farmers water their fields with water from the ground or river?
Irrigation.
WHAT are the disadvantages of using a tubewells?
Disadvantage of a tube well: -It is not possible where water-table is low. -If the groundwater is brackish then irrigation is not possible.
What is water harvesting?
Water harvesting is a method of collecting rainwater in storage tanks or pits which are dug underground; the purpose is to store the water for future use in irrigation or to increase the water table.
What is intake in irrigation?
Intake is an integral part of any irrigation system. The intake is where water is drawn into the irrigation system, either from a body of water or from a water system. This water is then distributed through the irrigation system to water the plants.
What is it called when farmers water their fields with water from the ground of a river?
