1. Soil Health and Ecological Resilience on the PalouseHealthy soil is critical for global food security and other essential ecosystem services but is threatened by processes of soil degradation, with at least 33% of global croplands estimated to be moderately or highly degraded. Current soil health assessments provide insight into soil functional performance but often lack diagnostic criteria that assess management effects on soil function over time. We integrate soil health assessments with ecological resilience theory to better understand management... A.G. Davis, D.R. Huggins, J.P. Reganold |
2. Managing Soil AcidificationThe presentation will explore the relationship between nitrogen fertilizers, soil acidity, and nutrient stratification in agricultural systems. We will discuss how N fertilizers contribute to soil acidification over time. The role of soil pH in nutrient availability and plant health will be highlighted. The discussion will focus on alternatives to mitigate soil acidification, such as lime application, balanced fertilization, and improved management practices, ensuring long-term... J. Souza, C.
