Title: Rainfall simulation to evaluate erosion control on TED research sites
Author: Ecological Services for Planning, Ltd.
Abstract: During a planning and modelling workshop hosted by Technology Evaluation and Development Sub-Program (TED) in November 1988, gaps were identified in the data being collected within the TED research. Many of the TED research projects were not obtaining data to quantify or evaluate the degree of erosion control provided by the farm management practices or technologies being tested. In order to address the gaps identified during the November 1988 workshop, TED collected runoff and erosion data on selected TED research sites in 1989, 1990 and 1991. Rainfall simulation was used as the tool to collect the runoff and erosion data. The Guelph Rainfall Simulator II was used, and the method of Agriculture Canada was followed under the initial direction of their staff at the Ontario Institute of Pedology. Rainfall simulations were conducted on research plots set up within ongoing TED studies, following consultation with the TED research contractor and the farmer cooperator. Runoff volumes and soil and phosphorus loss data were collected within one set of replications setup under the main research trials. This report provides a general background on soil erosion parameters, previous research with rainfall simulators and a description of the methods used in the TED rainfall simulation studies. Finally, the results of the each of the rainfall simulations on individual TED research projects are presented for each of the three field seasons.
