Different methods of Irrigation



Surface Irrigation
In this method water is distributed over the soil surface by gravity flow.  It is best suited for flat land slopes and to fine textured soil types which promote the lateral spread of water down the furrow and across the basin.

Subsurface Irrigation
In this method water is distributed below the soil and depends on the depth of the water table.  When the water level is well below the surface trickle / drip irrigation can be done


Drip Irrigation
In this method of micro irrigation water is supplied through emitters to the soil. The discharge rate in emitters is low so this irrigation can be used on all soil types

Sprinkler Irrigation
In this method water is sprayed and sprinkled through the air in rain like drops.  Both Permanent / Movable sprinklers are available and can be installed upon requirement.

Advantages of Drip Irrigation




Drip irrigation is a modern method in which water is delivered directly into the root zone of the plants. Drip Irrigation systems are able to supply small amounts of water at high frequency intervals. As a result, a relatively constant moisture level of the soil can be maintained.  This enhances good growth and production.

Traditional way of irrigating the entire field by flood irrigation results in significant loss of water.  In Drip irrigation water is saved and water in the wetted area increases the efficiency of water and nutrition uptake.

Advantages of Drip irrigation

Increases revenue from increased yield
Increases revenue from increased quality
Decreases water costs
Easy installation
No drift
No water being supplied to weeds
Decreases labour costs
Decreases energy costs
Decreases fertilizer costs
Decreases pesticide costs
Less evaporation of water compared to surface irrigation
No soil erosion
Improves seed germination
Improved environmental quality
Fertilizers can be directly applied efficiently through drip irrigation system
Drip irrigation can be used with polyethylene mulch which increases the yield further



In Drip Irrigation for effective result design is the key.  Lower salt content of the soil can be achieved by Drip Irrigation
