摘要

A soil model data storage unit 60 is provided with a soil model, a model for determining soil properties, a model for determining soil properties, and a measuring condition for identifying measurement data necessary to carry out the model, and a soil sensor s Based on the measured data, the water content ratio is detected by the water content ratio detecting unit 57, and the soil type is detected by the feature extraction unit 56 and the soil type discrimination unit 58, and is given to the decision unit 59. The determination part determines the corresponding measurement conditions and models based on the soil type and water content of the measurement point received, and sets it to a predetermined processing part. The measurement data corresponding to the measurement conditions from the soil sensor is supplied to the measurement information processing unit 55, and the processing part 55 obtains the soil characteristics according to the set model.
