The two grass species perennial ryegrass and smooth-stalked meadow-grass are the ”kings” to be used for heavy duty sports fields. This is due to the unique wear tolerance they both present and to the self-repair strength of especially smooth-stalked meadow-grass.
The slower establishment of the smooth-stalked meadow-grass is outweighed by the fast establishing perennial ryegrass and ProMaster has a well-balanced content of these two species. It is a given thing that the used varieties are selected from the highest rankings on European variety lists. In order to make the even higher safety and broad adaptability we use two different varieties of each species.
