A sufficient potassium (K) supply for whole crop silage maize is necessary for a good yield and nutrient efficiency for nitrogen and phosphorus. In a field trial in 2015, 2016 and 2017 the response of silage maize to K fertilization was limited, both for mineral K and K from cattle slurry, and surface spread and band application, at different levels of soil K supply; the response of K content and dry matter content was clearly present. No difference between mineral and organic fertilizer or surface spread and band application was found. The K-fertilization recommendation is based on K withdrawal by the crop with a negative correction when K-CaCl2 > 60.
