Phosphorus Uptake of Crops in Ontario Counties from 1961-2016

This research project aims to address the spatial and temporal evolution of anthropogenic phosphorus inputs into Ontario watersheds. Collected data includes number of livestock, area of crops grown, area fertilized, total cropland area, and population size in each county in Ontario. The outcome of the data processing was total kg of phosphorus per hectare added to the watersheds of Ontario, which was spatially represented in a map of Ontario. Note, that this data set is also collected 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

Annual crop uptake of phosphorus in kilograms for each census year on a census division scale, taken every five years beginning in 1961. Data were used in the Net Anthropogenic Phosphorus Inputs (NAPI) model. SGC or ID is the unique Standard Geographic Code that represents the county, Name is the name of the census division, and the region is the agricultural region the county is in: South (1), West (2), Central (3), West (4), North (5). The raw data were downloaded from the publicly available census available at: http://odesi2.scholarsportal.info/webview/ in the Agriculture tab. All data were standardized to the census division distribution in 2011, i.e. any divisions or subdivisions that were amalgamated into other divisions were accounted for.
