Summary translation

There is uncertainty as to whether S is a limiting nutrient for bread wheat in organic farming. Field trials at three locations were conducted for four years. Fertilization with sulphate or with slurry was tested, both separately and combined. 40 kg S or 40 kg Ntotal were fertilized, respectively, in early spring, with the exception of one of the three sites, where slurry was fertilized at BBCH growth stage 32 (early stem elongation). Slurry fertilization increased wheat yields by 9 % and improved wheat quality (protein content, Zeleny sedimentation index, wet gluten content, baking volume). In contrast, sulphate fertilization only increased baking volume and had no effect on yield, protein content, Zeleny index or wet gluten content. Therefore, slurry fertilization in particular can influence wheat yield and quality.
