Intercropped dyer’s woad increased the rooted zone and N retention in the agroecosystem. Complementary root systems reduced deep soil N and the risk of nitrate leaching. Leek growth and yield were not hampered by interspecific competition. Sowing dyer’s woad 5 weeks after leek transplanting had good performance.
