Soil moisture measuring system with gypsum blocks The soil moisture meter can be used in combination with soil moisture blocks (relatively cheap gypsum blocks). The soil moisture content is determined by measuring the resistance between two electrodes inside the gypsum blocks. The condition for reliable measurements is the optimal contact between sensor and soil.
The gypsum blocks are permanently buried in the soil at the desired depth. Once buried there the blocks have a life of 3 to 5 years (depending on the type of soil).
The meter is practical and is constructed in sturdy synthetic material. It has a measuring range of 0 - 100% for 3-100 kPa. The meter is applied in particular in places where a tensiometer cannot be used (dry soils). It is a system that provides an indication as to when irrigation is required. To achieve a series of soil moisture measurements the sensors can be connected to a datalogger.
