Soil Health Monitoring Using Sensor-Based Technologies: A Pathway Toward Sustainable Agriculture

Abstract

Soil health is a critical component of sustainable agriculture and long-term food security. Traditional soil assessment methods are often labor-intensive, time-consuming, and unable to provide real-time insights required for precision farming. Sensor-based technologies have emerged as transformative tools that enable continuous monitoring of soil parameters such as moisture, temperature, pH, electrical conductivity, and nutrient availability. These technologies facilitate data-driven decision-making, improve resource efficiency, and reduce environmental degradation. This article explores the role of sensor-based soil health monitoring in promoting sustainable agriculture, highlighting technological advances, applications, challenges, and policy implications. The study emphasizes that integrating IoT, artificial intelligence, and digital agriculture frameworks can significantly enhance soil management practices and climate resilience, particularly in developing agricultural economies like Pakistan.
