Irrigation Methods and Water Delivery

Irrigation is the process of delivering water to crops to maintain their growth and yield. There are different methods of irrigation, each with its own unique features and advantages. Some of these methods use open ditches for water delivery, while others do not. Let's take a closer look at each method:

1. Sub-irrigation
Sub-irrigation is a method of irrigation that delivers water to the crops from below the soil surface. This is done by raising the water table in the soil through the use of drainage tiles or pipes. The water then moves upward through the soil to the crop roots by capillary action. This method does not use open ditches for water delivery.

2. Trickle Irrigation
Trickle irrigation, also known as drip irrigation, is a method of irrigation that delivers water directly to the roots of the crops through a network of pipes and emitters. The water is released slowly and evenly, reducing losses from evaporation and runoff. This method does not use open ditches for water delivery.

3. Furrow Irrigation
Furrow irrigation is a method of irrigation that delivers water through shallow furrows or trenches between crop rows. The water flows down the furrows and infiltrates the soil to reach the crop roots. This method uses open ditches for water delivery.

4. Check Irrigation
Check irrigation is a method of irrigation that delivers water to the crops through a network of small ditches, or checks, that are built around the crop rows. The water is released into the checks, allowing it to infiltrate the soil and reach the crop roots. This method uses open ditches for water delivery.

Conclusion
Of the methods listed above, sub-irrigation and trickle irrigation do not use open ditches for water delivery. This makes them more efficient and effective in delivering water to the crops, while minimizing losses from evaporation and runoff.

Trickle irrigation means drip irrigation, drip irrigation method apply in the form of drops directly to the root.
drip irrigation can not related to open ditches
