Assessing cultivated cropland inherent vulnerability to sediment and nutrient losses with the Soil Vulnerability Index. Journal of Soil and Water Conservation. 75(1):20A-22A. https://doi.org/10.2489/jswc.75.1.20A. DOI: https://doi.org/10.2489/jswc.75.1.20A Interpretive Summary: The Soil Vulnerability Index (SVI) utilizes soil properties and topographic slope to classify inherent vulnerability of cropland to loss of sediment and nutrients by runoff and leaching. Management is not taken into account in this classification, except for the presence of artificial drainage. In this introduction to a special issue focused on SVI evaluation, we present the goal and purpose of SVI, explain the history of its development, show examples of SVI uses, and introduce each of the papers in this special issue. The goal of this paper is to place the SVI evaluation across 13 Conservation Effects Assessment Project (CEAP) watersheds within the broader context of SVI development, testing, and evaluation, followed by improvement and further evaluation. This context will be useful to readers to interpret the findings of the SVI evaluation.
