This guide explores the importance of soil fertility and reseeding methods to mitigate losses of over €300 per hectare in dairy farming. Based on Moorepark research, it highlights the timing, variety choices, and management practices necessary for successful reseeding. Lessons on soil testing, lime requirements, and nutrient status (P&K) are discussed, addressing the pitfalls of low soil fertility. The aim is to improve grass production and utilization while offering strategies for effective grazing management, ensuring optimal farm returns in the long run.
