Soil sensors provide valuable data for agriculture, but their accuracy can vary. Factors like soil bulk density, mineralogy, and salinity impact sensor calibration, resulting in ± 3-5% accuracy. Soilless growth substrates may have a higher margin of error due to different properties. Calibration for specific soil types and conditions can help improve sensor accuracy. Regular calibration and consideration of soil properties are essential for obtaining precise soil sensor measurements.
Due to variations in soil bulk density, mineralogy, texture, and salinity, the generic mineral calibration for current METER sensors results in approximately ± 3 to 4% accuracy for most mineral soils and approximately ± 5% for soilless growth substrates (potting soil, stone wool, coco coir, etc.).
