Moisture sensors are crucial for efficient irrigation, but determining their depth is key for accurate readings. Placing sensors at various depths can provide a comprehensive view of soil moisture levels.
Consider these factors when deciding how deep to install moisture sensors for different types of crops:
1. For shallow-rooted crops, place sensors at 5cm, 10cm, and 20cm depths.
2. For deeper-rooted crops, consider depths up to 2 meters, including 150cm and 200cm.
3. Adjust sensor placement for tree crops and areas with capillary rise benefits.
Proper depth placement ensures effective water management for optimal crop growth.
Thus sensor are installed at 5cm 10cm 20 cm, 50 and 100cm. If the crop is a depth rooted crop observe in addition to the above 150 and 200 cm i.e upto 2 meters. Case of tree crops and areas where the plant may benefit from water table capillary rise the installations of these sensor may be varied appropriately.
