Step 1: Understanding basin irrigation.
In basin irrigation, circular or square basins are formed around the plant base (especially fruit trees). Water is applied to the basin so that it seeps down to the root zone. Step 2: Diagram requirements.
A correct diagram should show:
- A tree at the center.
- Circular basin around the tree.
- Water stored within the basin.
- Arrow showing seepage into the root zone. Step 3: Importance.
This method ensures efficient water use and is highly suitable for orchards.
