Q.28
The operational range for electrical resistance block is
- Electrical Resistance Blocks (Gypsum Blocks): Measure soil moisture tension by calibrating electrical resistance across embedded concentric wire electrodes inside a porous calcium sulfate block against soil water potential.
- Operational Range: Gypsum blocks function effectively in intermediate to dry soils ranging from -0.5 to -15 bars (-0.5 to -50 bars).
- Limitation: In very wet soils (0 to -0.3 bars), gypsum blocks are insensitive because the pore water within the block remains saturated, whereas tensiometers operate best in the wet range (0 to -0.85 bars). (Correct answer: Option 3)
