Estimation of the Inorganic Nitrogen Content in the Soil Using a Soil Sensor in Tea Fields

Key Points

• The aim is to develop a method for estimating inorganic nitrogen content in soil using a soil sensor.
• Calibrated the soil sensor for moisture content in laboratory tests.
• Installed the sensor in the field for data collection.
• Obtained 14 sets of data including moisture content, electrical conductivity, and nitrogen levels.
• Applied the Rhoades model to determine parameters and estimate nitrogen content.
• Developed a formula to estimate inorganic nitrogen levels in soil.
• Achieved real-time monitoring of soil nitrogen content from a distance.
• Validated measurements with multiple soil properties.
