MARATHON GOLF Patented long-lasting
organic mineral fertilisers

Marathon Golf steadily releases nutrients and the organic matter stimulates a very active bacterial soil life. This results in healthy, strong and compactly growing turf. Marathon Golf ensures active root development, a denser sod, improved resistance to stress and increased tillering of the grass.

The situation

Maintaining healthy and strong greens

Golf is a sport played all year round. The seasonal changes in turf growth and weather create challenges for keeping greens in optimal shape.

The challenge

Balancing growth and resilience

Often vital growth limits the resilience of turf as vegetative growth is often a synonym for vitality. Nitrate-based fertilisation leads to too much vegetative growth, which is counterproductive for disease tolerance. Ammonium-based nutrition favours cell division over elongation. However, ammonium is converted to nitrate very rapidly. The challenge is to keep the nitrogen in such a form that prolonged ammonium nutrition is possible.

The solution

Marathon ammonium feeding

The mini-granules of Marathon Golf fertilisers are based on carefully selected plant sources and combine organic matter (for buffering nutrients) with agricultural fertilisers. Marathon's patented organic buffer complex ensures the steady release of ammonium and other nutrients. It prevents nutrients from leaching and keeps them available for up-take as and when required by the turf. Moreover, the organic matter stimulates a very active bacterial soil life that reduces the build-up of organic matter and decreases compaction. Marathon ensures active root development, a denser sod, increased tillering of the grass and improved resistance to stress.

Recommended products

The Marathon Golf range provides strong and resilient turf. Given that greens are the ultimate place for stress accumulation, we also recommend the use of the Melgreen Liquid prevention range.
