Improving highbush blueberry nitrogen management with nitrification inhibitors

The objective of this study was to assess the effects of nitrification inhibitors, applied with two nitrogen fertilizer rates (60 vs. 120 kg N/ha) and two fertigation systems (suspended vs. buried), on blueberry yield and soil nitrate and ammonium levels.In British Columbia (BC), ammonium sulfate…

Economic and environmental benefits of reducing nitrogen fertilization in potato fields

This study evaluated the economic and environmental tradeoffs of three nitrogen application rates (0, 90, and 120 kg N per hectare) in potato production.Decades of intensive cultivation, along with challenges caused by inherent soil properties (poor drainage, fine soil textures), in the Fraser…
