RUSLE2 - Revised Universal Soil Loss Equation Version 2

RUSLE2 was developed primarily to guide conservation planning, inventory erosion rates and estimate sediment delivery. Values computed by RUSLE2 are supported by accepted scientific knowledge and technical judgment, are consistent with sound principles of conservation planning, and result in good conservation plans.

RUSLE2 is an upgrade of the text-based RUSLE DOS version 1. It is a computer model containing both empirical and process-based science in a Windows environment that predicts rill and interrill erosion by rainfall and runoff. The USDA-Agricultural Research Service (ARS) is the lead agency for developing the RUSLE2 model.

Windows Pesticide Screening Tool

The Windows Pesticide Screening Tool (WIN-PST) can be used to evaluate the potential for pesticides to move with water and eroded soil/organic matter.  Long-term human and fish toxicity data and ratings are also included with WIN-PST.  These toxicity ratings can be combined with the off-site movement potential ratings to provide an overall rating of the potential risks from pesticide movement below the root zone and past the edge of the field.
