Abstract
The Stewardship Tool for Environmental Performance (STEP) is an expert system for field conservationists to evaluate water quality benefits of management techniques and conservation practices applied to agricultural land. The tool computes nutrient leaching and runoff potentials, sediment runoff potentials, pesticide leaching and runoff potentials, as well as pesticide hazard ratings for farm fields based on local conditions. From this STEP computes minimum threshold levels reflecting the level of treatment needed to mitigate the loss potentials and hazards. The tool then provides a process for applying mitigating technique and practice scores to meet or exceed thresholds. The nutrient component of STEP results from analysis of the millions of APEX model simulations used in the USDA Conservation Effects Assessment Program (CEAP) completed for the major river basins of the United States since 2002. CEAP estimated the environmental benefits of conservation practices at the river basin level and in 2011 incorporated the knowledge into STEP. The pesticide component of STEP results from more than two decades using the stand-alone Pesticide Screening Tool application, which has roots in the CREAMS and GLEAMS models. As part of the effort to integrate resource assessment at the farm field level, we describe a suite of 22 microservices supporting the STEP workflow. We make these services available through the OMS/CSIP continuous integration process.
