High potential contribution of intercropping to soybean and maize self-sufficiency in Europe

A study finds that intercropping maize and soybean in Europe could significantly boost soybean self-sufficiency while saving land compared to sole cropping. Depending on the scale, intercropping could achieve up to 75% soybean self-sufficiency and reduce land use by about 20%. Full self-sufficiency may require intercropping on over 25 million hectares, about 23% of European cropland.
