Monitoring Soil Health through Citizen Science

By Sandra Arango-Caro and Terry Woodford-Thomas MO DIRT, Missourians Doing Impact Research Together, is a program that educates individuals on soil science and engages them as citizen scientists. These volunteers contribute baseline information that helps our understanding of the current health status of Missouri soils. Soil health is the ability of the soil to function as a vital ecosystem that sustains living organisms, their processes, and environmental quality. Human existence is determined in part by soil health because of its critical role in food security and climate security.  Citizen science…
