Soil type, air type, water type, ion type . . . variables abound in EC measurement, but Murata EC sensors eliminate the uncertainty with multiple measurement patterns, and by changing resistance measurement ranges (cell constants).
< Example measurement patterns of Murata’s nine-electrode EC sensor >
With its three elements—grains, air, and pore water—soil is impossible to measure accurately with few electrodes due to the outsized impact of water content. However, Murata soil sensors are equipped with proprietary algorithms that make it possible to measure fertilizer content only.
Soil comprises three elements: grains, air, and pore water.
Conventional EC sensors are impacted by the amount of water and fertilizer in soil.
Bulk EC is problematic because it considers all three soil elements to be resistors, and higher resistance values are more susceptible to the amount of water and fertilizer (ion) present.
Murata soil sensors use proprietary algorithms to measure fertilizer content only.
To grow crops, farmers need to know the amount of fertilizer ions present in pore water, and crop growth depends on the fertilizer content in pore water. It is also important to avoid contaminating the water by over-fertilizing or accumulation of chemical fertilizers in soil due to constant fertilization.
Murata’s sensors provide unfailingly accurate water content measurements with algorithm-enabled correction of temperature dependence and high-frequency measurements that control the impact of ions.
