Irrigation branch canals: farmers' adapted design (-)
Establishing the system of water drainage ditches - Lampradong Rongnam (irrigation branch canals) is the technology developed from struggling in managing water and soil for farming before 1993. Learning to modify the system was derived from using the labor required to move pumps and equipment to pump water at various locations. This created an exhausting and time-consuming task. Moreover, land could not be developed and the water could not be controlled as required either. Therefore, setting up a system of irrigation branch canals arose from this. The system was then designed to counter acidity and neutralized it from the soil. As a result, rice could be grown, giving a good yield. At the same time, water could be controlled in rice farming throughout. To set up a ditch-branch watercourse comprises ditches of 50-100 centimetres wide, and 100 centimetres deep. Both sides of the ditch consist of ridges that can be modified -either side- to be a path to deliver materials and equipment in doing rice farming and productivity form the paddy. The path to convey materials is 1.9 -2.5 meters up, depending the objectives of the owner of the area. For the levee on the other side, it is 50-100 centimetres wide with a height of 50 centimetres. In the rice farming area of farmers in Ongkharak district, Nakhon Nayok province, there are paddy areas divided into plots. Each plot has an area of 3.2-6.4 hectares. The areas required to establish these canals are about 1,640-3,200 square meters. Farmers not only prefer this adapted technology but it also reduces labour in managing rice farming.
