Pros and Cons of three types of water irrigation

Drip irrigation uses a system of tubes looped around each plant at soil level so that water can seep into the ground for instant moisture and can be controlled manually or timed with a timer.
Pros
-concentrating the irrigation to specific plants prevent weeds from growing nearby.
-retaining the moisture at the soil level also reduces water loss to wind and evaporation.
-the tubes supply an even amount of water to each plant.
-maintains a healthy soil environment with no muddy or drought areas.
- less runoff to local drains so soil keeps nutrients and reduces ground water pollution.
Cons
- bad installation often leads to poor root development and die back.
- very expensive
- the system needs periodic flushing to remove mineral build up and the farmers will have to check every single emitter for any blockage so water pressure does not build up within the tubing and damage the entire system.




Irrigation sprinkler system functions by dispensing water to the air to fall like natural rain.
Pros
- is ideal for most crops and so more adaptable to many irrigable soils.
- very efficient 
Cons
- can be impacted by wind
- some crops are affected by leaf scorch, fungal disease along with other damage which may be caused by salt being deposited on the leaves.
- costs a lot of money and requires lots of maintenance.


Surface irrigation
Pros
- less affected by climate and water quality factors .
- large areas can be irrigated
-floods can be controlled
Cons
- less efficient than other systems 
- difficult to engineer and very labor demanding
-drainage can also be a problem in some circumstances
-amount of available water varies from year to year.
-sediments in the irrigation water if not taken care of can lead to problems with crops and soil.


      farmers should use drip irrigation systems. It would be very expensive but what system is not? Also you would have to check every emitter to see if there is a blockage but it uses much less water. The water in the other system uses to much water and becomes polluted runoff or just makes weeds. Water is a very valuable resource and is starting to dry up so the country needs to think about that.
