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…
Balancing nitrogen and phosphorus on vegetable farms in southwest BC
To better understand the tradeoffs farmers face between nutrient management strategies, we evaluated three different approaches in two years of field trials across 20 mixed vegetable farms located in Pemberton, Vancouver Island, and in the Fraser Valley.Like many crops, vegetables require…
KPU Southwest British Columbia Small-Scale Farm Enterprise Budget 2015: Potato
This enterprise budget presents costs and returns for one acre of potatoes grown on a small-scale mixed vegetable farm in southwest British Columbia, Canada.
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…
