Organic farming impact on soil health indicators across 9 yr of management in a US Midwest Mollisol
This dataset contains soil health indicator data across 9-yr (2012-2020) from an experiment evaluating conventional corn-soybean, organic corn-soybean-oat/alfalfa-alfalfa, and an organic perennial pasture near Boone, IA. The soil samples were collected annually and analyzed using standard methods. The soil properties used as soil health indicators were: microbial biomass C, potentially mineralizable C and N, pH, wet-aggregate stability, and concentrations of organic C, total N, inorganic N (NH4 and NO3), P, and K. Such data were collected to answer key farmer questions regarding changes in soil health under organic farming. Data were presented in Ruis et al. (2025), Soil Science Society of America Journal (https://doi.org/10.1002/saj2.20795).
