Nova Scotia Federation of Agriculture

Reducing nitrate loading to groundwater by delivering site-specific N fertilizer recommendations



  • Replicated sampling of 50 to 100 agricultural fields across Nova Scotia encompassing a range of climatic regions, soil types, cropping systems and fertility management systems
  • Analyzed samples to determine a range of soil physical (texture, bulk density), chemical (soil pH, standard fertility analysis, mineral N) and biological (organic C, total N, biological N supply, particulate organic matter) properties to determine both the variation and extent of these properties in Nova Scotia soils


  • Prepare position paper on use of soil N supply calibration functions
  • Groundwork for future research


  • Recommendations for a measurement-based approach to improved nitrogen management in Nova Scotia, which include:
    • Soil Nitrogen Supply Test
    • Estimation on N mineralization
    • Nitrate Exposure
    • Residual soil N
    • Partial N Balance
