1. Impacts of Management Practices and Soil Properties on Free-Living Nitrogen Fixation in Southeastern South DakotaModern agriculture relies heavily on synthetic nitrogen fertilizer, raising environmental concerns due to overuse. Biological dinitrogen (N2) fixation offers a sustainable alternative, with free-living diazotrophs playing a crucial role alongside well-known symbiotic nitrogen-fixing bacteria. Recently, interest in free-living nitrogen fixation (FLNF) has grown due to its potential contribution to sustainable agricultural practices. However, there is limited scientific data on FLNF in...

2. Evaluating Classification Methods for Phosphorus Responsiveness for Fertilizer RecommendationsField crop yield responses to fertilizer applications are often uncertain, and the likelihood of a response at a given site is typically determined using correlation-based soil test methods whose accuracy is not well established. The objective of this study was to evaluate three alternative approaches to classify field sites as responsive or non-responsive to phosphorus (P) fertilization in wheat. The methods tested were: (i) a linear-plateau correlation model, (ii) a linear-plateau correlation... D. Ruiz diaz, S. Cominelli, J. Lacasa |
