Soil quality research focuses on assessing the health and fertility of soil in agricultural and environmental contexts. This research area typically involves analyzing various physical, chemical, and biological properties of soil to determine its overall quality and how to improve it for optimal crop production or ecosystem health. Researchers in this field may examine factors such as soil pH, nutrient levels, microbial activity, and soil structure to understand how these elements impact soil health and productivity. The ultimate goal of soil quality research is to develop sustainable practices and management strategies that maintain or enhance the quality of soil for long-term use.
