Electrical Resistance Blocks - Introduction
addition of a small quantity of gypsum to the back-fill soil at the time of installation. A small quantity of lime (CaCO3) may likewise be useful in a acid soil in prolonging the life of a block. Most electrical resistance blocks monitor soil moisture more effectively in the drier range of soil water tensions (in excess of 0.33 bar).
Soil moisture sensor - Wikipedia
Soil moisture sensors measure the volumetric water content in soil. Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the ...

The main advantage of the gypsum block method is that they are suitable for monitoring soil water status below crops and plant communities continuously. After installation the nylon-impregnated blocks can be left in place for years and measurements may be taken from outside the crop stand thus avoiding any disturbances of the plants environment.

The technology is a significant improvement on older, tensiometer and gypsum block style sensors by requiring zero maintenance, having a higher accuracy and being more robust. The technology is called the MPS-6 Soil Water Potential Sensor and includes the latest digital specs to integrate with IoT and telemetry platforms .
Irrigation scheduling with gypsum blocks in Austria
The regressions between soil water potential and the sensor resistances were similar at least in that region of soil water tension which is relevant for the indication of irrigation needs of most field crops in eastern Austria: a meter reading of 20 units corresponds to soil water tensions ranging from 0.20-0.24 MPa, depending on the block type used.

Soil Moisture Sensors – Grapes
Electrical resistance blocks are also known as gypsum blocks or soil moisture blocks. They are simple devices with two electrodes embedded in a block of gypsum or other similar material. When blocks are buried in soil, water moves into or out of the block, depending on the moisture of the soil, changing the resistance between the two electrodes.

1. Sensor: The analysis indicated that the gypsum block is a viable choice to take soil moisture readings. The gypsum block, shown in Figure 1, is a cylindrical block of gypsum in which two electrodes are inserted. The gypsum is porous and allows water to move in and out of the block as the soil wets and dries. When the block is excited
