Anthropogenic Phosphorus Mass Balance in Ontario Counties and Watersheds

Description: Parameters from the Net Anthropogenic Phosphorus Inputs model (NAPI) estimated on a county scale: annual crop uptake of phosphorus, annual net input from livestock (i.e. manure), annual phosphorus from milkhouse runoff, annual phosphorus applied as fertilizer, annual phosphorus inputs from domestic detergent use, and annual human phosphorus consumption in kg. Values were compiled from the Agricultural Census and the Population Census from Statistics Canada for each census year which occurred every five years beginning in 1961, values in between were linearly interpolated. Phosphorus content values for detergent, livestock, crops, and human consumption were compiled from literature (see individual spreadsheets for more information). ID is the Standard Geographic Code that represents the county, standardized to 2011. The region represents the agricultural region the county is in: South (1), West (2), Central (3), East (4), North (5). The raw data were downloaded from the publicly available census available at: in the Agriculture tab. Suppressed data were estimating using residual hectares unaccounted for in the region totals and historical trends. All data were standardized to the census subdivision distribution in 2011, i.e. any divisions that were amalgamated into other divisions were accounted for.

This data set was produced to support the objectives of two projects. These are: 1) Legacies of Agricultural Pollutants (LEAP) funded by Natural Sciences and Engineering Research Council of Canada and other international partners. 2) "Lake Futures: Enhancing Adaptive Capacity and Resilience of Lakes and Their Watersheds". Lake Futures is a Pillar 3 project under the Global Water Futures Program funded by Canada First Research Excellence Fund.
