Soil health assessment involves the measurement and interpretation of multiple chemical, physical, and biological soil attributes that contribute to soil function. The concept of soil health arose from decades of soil conservation efforts and the recognition that soils play a key role in sustained agricultural productivity and environmental quality. The challenge of integrating and interpreting multiple soil health indicators led to the development of the Soil Management Assessment Framework (SMAF), an index that currently handles 13 indicators and accounts for site-specific characteristics, such as soil texture, mineralogy, and climate. Recent advances in biological techniques have thrust soil microbiology to the forefront of soil health research. Biological measurements, however, are costly and often exhibit high spatial and temporal variability. Therefore, development of a reliable, affordable, and high-resolution soil health assessment depends on continuing innovation in laboratory and field techniques.
