How drip irrigation turns the way of agriculture?

By Edited Nov 13, 2013 0 0

Drip irrigation is one of the old methods of 60s. At that time it is one of the only underground irrigation methods developed. The cause which led to the knowing of this amazing method of irrigation was never commercial. It all started from the position where the tree was situated near a running tap which leaked drop by drop and indeed the tree was well large than all its siblings around. It was from then, that this method of drip irrigation also called as the drop by drop irrigation was practiced and has been very successful and evolving out at recommendable pace.

Drip irrigation System is simple enough to understand. In fact its name itself is quite self explanatory and very well proclaims the entire method and procedure of approach. By the name drip irrigation it is also called as the drop by drop irrigation or underground irrigation. The main objective of such an irrigation practice is to provide the water supply till the active root zone of the tree which may be fairly deep for fully grown trees. Another thing that brought light upon this fantastic find of irrigation besides the deep reach for irrigation is the method being very conservative in terms of water. Drip irrigation has significantly reduced the amount of water lost by the wasteful methods like runoffs and evaporation. In addition to the usual drip irrigation, today's modern agriculture also uses a plastic sheet to further reducing water loss from evaporation and may be used for fertilizing as well. This method of drip irrigation and plastic sheet is together termed as fertigation (fertilization+ irrigation).

Drip irrigation does not require very high sophisticated system. This type of irrigation only depends upon the drip irrigation supplies and the time till which the drips are continued. If the time is prolonged or drip rate is increased the irrigation extends deep beneath the root level giving a uniform irrigation to the plants in the area. This drip rate may be controlled technically with the help of machines or may be simply controlled by labor structures. Other thing to be kept in mind is that, the pressure requires is not high here, mostly the pressure may be low. As the drip rate is finally to be adjusted at the end.

The pressure may be kept constant for flat terrains but in case where the terrain is not so smooth other irrigation facilities fail to deliver the required results. But the process of drip irrigation is quite efficient even in the places with rough terrain here by simply adjusting the pressure by pressure compensating emitters the drip can be very well handled.

This drip irrigation is mostly underground and it is the primary step to first filter and regulate the pressure of the water supply before the drip mechanism is set functional. Also the drip tubes may be made to be of different colors thereby making a distinguishing factor among them. This distinguishing may be on the basis of the pressure that prevails in the tube. The underground nature of the irrigation system prevents the growth of algae and has prevented faster degradation of the tubes. The drip irrigation has much more modified branches as that of the porous clay vessel modification that retains water and is filled time to time to facilitate irrigation.
