Abstract:
... Decision-support tools (DSTs) are a type of innovation that can facilitate science-based decision-making, including nonpoint source pollution management in agricultural watersheds. However, organizational readiness for adopting innovations is a topic that has received limited attention in the literature. With the goal of filling this knowledge gap, we draw upon the diffusion of innovations (DOI) t ...

Abstract:
... In soil enzyme assays, buffers are most commonly employed to constrain the assay to a specific pH at which activity is assumed to be maximized (i.e., pH optima). The assumed pH optima prescribed for the assay of soil β-glucosidase and phosphomonoesterase activities are based on early studies from a limited set of soils and have subsequently been found to be invalid in broader contexts. Here, we us ...
