Abstract
Italian ryegrass (Lolium multiflorum) is studied in pot experiments on a soil of low potassium status. Different methods of applying potassium are compared which result in different dry-matter yields in successive cuts; the effect of the different K applications are also compared on the decreasing or improving evolution of the K soil status during and after the cropping. The compensation with amounts of K corresponding to the K uptake of the previous cut is particularly interesting in terms of fertilizer efficiency.
