dc.description.abstract The soil baseline program began in 1980 and is part of the Ministry of Environment's Acidic Precipitation in Ontario Study (A.P.I.O.S.). The major objectives of the soil baseline program and methods used to sample soils are provided in Volume 1. In addition, the glacial history of Ontario, some theories of soil development, and the effect of acidic precipitation on soils are briefly outlined in Volume 1. Over 300 locations were sampled in 1980 and 1981 throughout the province. A reliable, current and uniform data base for soils across Ontario now exists and is presented in Volumes 2 (Analytical Data for Southern Ontario) and 3 (Analytical Data for Northern Ontario) of this report. This data base is being used by A.P.I.O.S. researchers to produce a map which will show the relative sensitivities of Ontario soils to acidic deposition. Resampling baseline soil profiles over an extended period will also provide a means of monitoring trends in soil chemistry due to environmental stress. This report is mainly a presentation of field and laboratory soil information (Volumes 2 and 3). Each baseline site has been given a 6 digit location code number. Within each region, sites are presented in ascending order based on location code number. The numbers which appear on Maps 3 to 8 in Volume I correspond to the last 3 digits of the location code. Soil samples were analyzed at the Ministry's central laboratory in Toronto for pH, texture, extractable iron, aluminum and manganese, inorganic and organic carbon, major cations (NaCl exchangeable), CEC (sum of cations measured), anions, and trace metals (HNO3 - HClO4 extractable). Further description of the analytical methods can be found in Volume 1 and in the "Procedures Manual Terrestrial Effects, Acid Precipitation in Ontario Study" (A.P.I.O.S.) Report No. 007/83 Ontario Ministry of the Environment. Data are reported to two significant figures. For the 14000, 17000 and 18000 series samples, organic carbon values were rounded to the nearest percent. This has since changed to provide better data at low levels.
