season / month1. System Design and Layout The first step involves designing a drip irrigation system tailored to the specific needs of the agricultural land, considering factors like crop type, soil composition, and topography. The layout should ensure even distribution of water to all plants. 2. Water Source and Filtration Identifying a reliable water source is crucial. The water must be filtered to prevent clogging of the drip emitters, which could result from sediment, algae, or other particulates. 3. Installation of Main and Sub-Main Pipes These pipes transport water from the source to the fields. Their size and layout depend on the field's size and the water flow rate required by the crops. At sowing 4. Distribution Lines and Emitters Flexible tubing or drip tapes are installed along the rows of crops, with emitters placed at intervals to deliver water directly to each plant's root zone. The emitter's flow rate can be adjusted according to the crop's water needs. After emerging 5. System Management and Maintenance Regular monitoring and maintenance are essential to ensure the system's efficiency. This includes checking for leaks, cleaning filters, and flushing the system to prevent emitter blockage.
