Title: A comparison report of cropping tillage and land management practices in Southwestern Ontario for 1986 and 1991
Author: Roberts, Peter; Aspinall, Doug; Koppen, Susan
Abstract: The two survey years were shown to be representative samples stratified on the basis of township. The 141 townships originally in the 1986 survey were re-visited to produce a statistically reliable sample to bench mark data collected in 1986. Environment Canada's erosion potential maps were utilized to designate each site visited as having a "high", "low", or "random sample" designation. Overall the study area stratification ratio was unchanged for both survey years, namely 83.5%low or random to 16.4% high in 1986 and 83.7% low or random to 16.3%in 1991. The goal of this study was to assess whether agricultural management practices have changed since the bench mark study in 1986 and if so, what impact these changes could have on phosphorus delivery to the Lake Erie basin. In order to achieve this goal, the following agricultural management practices were assessed for change: 1. Cropping, tillage and planting practices 2. Nutrient management practices (eg. manure and fertilizer application) 3. Erosion control practices (eg. field borders, ditch bank stabilization) 4. Drainage practices. Some agricultural demographic information was collected so that the surveyed farms could be more easily characterized. The interpretation of the results will demonstrate the effectiveness of soil and water conservation measures at the end of the SWEEP Agreement.
