SOIL ENVIRONMENT PREDICTION SYSTEM FOR FARM CROP, SOIL ENVIRONMENT PREDICTION DEVICE FOR FARM CROP, AND SOIL ENVIRONMENT PREDICTION METHOD FOR FARM CROP

摘要

To provide a soil environment prediction system for farm crops that enables comprehensive management judgement that predicts soil conditions based on solar heat use by not only performing soil sterilization but also predicting physical properties, chemical properties, and biological properties of soil.SOLUTION: A soil environment prediction system for farm crops of this invention has a step of storing a cumulative earth temperature for judgement, a step of setting measurement start, a step of storing measured earth temperature in soil, a step of setting a judgement date, a step of calculating cumulative measured earth temperature in soil, a step of obtaining observed weather data, a step of obtaining forecast weather data, a step of calculating a converted earth temperature, a step of calculating a forecast converted earth temperature, a step of calculating a correction value, a step of calculating a forecast converted cumulative earth temperature, a step of calculating a total cumulative earth temperature, a judgement step, and an output step.SELECTED DRAWING: Figure 1
