The Master Leys range of grass mixtures offers full and comprehensive options for all types of farming systems and regions of the UK.
Working in close coordination with leading grass seed breeders throughout the UK and Europe, we are able to access the best varieties to formulate the Master Leys and Kingsford portfolio.
In addition to this, we grow and produce over 80% of the grass seed used to produce Master Leys. This enables us to have a greater control over the quality of the seed we use and ensures that what goes into a Master Leys bag is of the highest possible standard.
At Agrii, we believe that giving specific advice on increasing quality home grown forage is the key to maximising an individual livestock farm’s productivity.
