A new combination of cropping practices appears to solve some disease problems in continuous wheat culture. Wheat straw is not toxic to wheat plants, but keeps the soil moist and favors disease. Cook suggested the following system: no-till, paired row, fertilizer placed beneath each row. The fertilizer shank disturbs the soil and inhibits certain disease organisms. Each plant has easy access to fertilizer beneath, and the P helps the seedling grow out of disease injury that may occur. P also stimulates root growth. The paired row opens up the canopy to some drying, which stops take-all and Rhizoctonia. This system is working in continuous no-till winter wheat in Pullman, and is also working in continuous no-till spring barley at Lind, WA. Cook suggested its use in the intermediate rainfall area. The fertilizer is placed at 5" depth and the seed at 1.5".
