In recent years, technological innovations have revolutionized our approach to understanding and managing soil health.
Traditional methods of soil assessment have given way to sophisticated, data-driven technologies that provide unprecedented insights into soil conditions.
Historically, we focused primarily on soil fertility and nutrient levels, guided by Liebig’s Law of the Minimum.
However, the concept of soil health broadens our perspective beyond just promoting plant growth. It emphasizes the importance of sustaining diverse organisms and maintaining the soil’s functional capacity to provide essential ecosystem services, such as nutrient cycling, carbon sequestration, water quality regulation and biodiversity conservation.
Thus, assessing soil health requires examining a complex interplay of physical, chemical and biological factors, including soil structure, aggregate stability, pH, organic matter content and microbial activity.
Modern monitoring
Farmers in the 21st Century are focused on managing their fields efficiently and committed to adopting innovative practices that enhance and sustain soil health. This shift has increased the demand for monitoring and assessing soil health parameters.
Technology advances have introduced various tools for soil health monitoring through digital soil mapping by using remote and adaptable field sensors, spectroscopic tools and drones. These tools facilitate immediate insight into soil conditions sometimes directly in the field, allowing farmers to make informed decisions based on real-time data.
