To meet the increasing demand for forage quality from grassland, different strategies of reseeding are used in practice. Commercial seed mixtures are usually sown with different overseeding techniques such as slot-drill machines or combined harrows. Natural self-seeding could be an interesting alternative to improve grassland stands without any technical effort. Two field trials have been carried out by AREC Raumberg-Gumpenstein to investigate different methods of grassland renovation in mountainous regions with consideration of technique, frequency, seed mixtures and also natural self-seeding. The efficiency of natural self-seeding was studied by quantifying the total seed-amount, the species spectrum, and by testing the germination capacity of the seeds. Yield and forage quality were considered as well as the botanical composition of the treated plots.
