Intercropping Pea with Canola or Oat: impact on nitrogen, disease and economics

Intercropping pea with oat or canola enhances biodiversity and likely increases resource (e.g. nitrogen, water, and phosphorus) use efficiency. The improved quality and quantity of straw from the intercrops likely affect straw decomposition, soil carbon and N dynamics, and soil health. In this study, the effects of intercropping on soil particulate organic matter carbon and N will be determined. This study will be conducted at three sites in Saskatchewan. This project is co-funded with ADF and will be completed in 2024.
