Nitrogen sensor
An agricultural device that measures nitrogen levels in soil or crop canopy to assist in precision nutrient management.
Также говорят: N-sensor, crop nitrogen sensor, optical nitrogen probe
Nitrogen sensors are essential tools in precision agriculture designed to monitor the nutrient status of crops throughout the growing season. Agronomists use these devices to determine the optimal timing and rate of nitrogen fertilizer application based on the actual requirements of the plants.
Implementing this technology helps improve input efficiency, maximizes yield potential, and reduces environmental impact by preventing nutrient leaching. Sensors typically collect data on vegetation index or soil electrical conductivity to guide variable-rate application systems.
Common operational mistakes include failing to calibrate the sensors for specific field conditions and neglecting the influence of abiotic stress factors on plant uptake. Relying solely on sensor data without verifying soil moisture levels can also lead to inaccuracies in nutrient mapping.
