Growing crop mixtures can increase yields, reduce input costs and support biodiversity. We have identified species/variety combinations, management conditions, and machinery adaptations that optimise these benefits from crop mixtures. This work has direct impact on farming practice and uptake by Scottish farmers through >50 collaborative trials to grow mixtures on farms across Scotland. By working with farmers to design and monitor trials, we are quantifying mixture performance relative to monocrops and demonstrating the technical feasibility of mixture cropping.
