What is the function of a soil health assessment?

The function of a soil health assessment is to evaluate soil properties that affect nutrient supply. This process involves measuring various soil characteristics, such as texture, structure, organic matter content, pH, and biological activity, which all influence how effectively soil can provide nutrients to plants. Understanding these properties helps land managers and farmers optimize their nutrient management practices, improving crop productivity and sustainability.

While other choices present important aspects of soil management, they do not capture the primary focus of a soil health assessment. For instance, measuring water retention is significant for irrigation practices but does not directly relate to assessing nutrient supply. Similarly, while checking for pests and diseases is crucial for overall crop health, it falls under the category of plant health rather than soil health. Adjusting soil acidity can be beneficial for crop growth, but it is a more specific action rather than a comprehensive assessment function. Therefore, the core goal of a soil health assessment is its role in evaluating the properties that determine how well soil can supply essential nutrients for plant growth.
