Rotations: How do I choose? CELUP Oak Park IPM benefits/ Concerns Importance of a good rotation - Profitability - Disease (Take all) - Diversify risks - Volunteer weeds - Fulfil greening regulations - Disease carry over - Effective use of herbicides on difficult weeds - Fertility issues - Soil structure benefits Yields & Margins: Long term Oak Park trials Winter barley yield and margin BC: +9% Key Messages - Rotations are farm specific - Assess overall financial margin of rotation
