Establishing Soil Health and Carbon Targets

Interpretation of any soil health indicator requires defining what values are ideal.

Overview

Soils can exhibit different ranges of indicator values depending on site characteristics, including precipitation, temperature, soil types, and topographic position. In this project the Soil Health Institute worked in Texas and Arkansas to demonstrate that grouping soils according to the inherent properties makes it possible to link soil health indicator values to differences in management, rather than natural variation across sampling locations. The potential soil health and soil carbon of each group of soils can be established by measuring soil health indicators under management conditions that exemplify the soil health principles, including minimal soil disturbance, continuous living roots, and physical protection of the soil surface. The methodology developed in this project is the basis for establishing soil health and carbon targets across the Soil Health Institutes’ programs.
