|Good fertilization is necessary for perfect grass cover. People cannot live without nutrition, and neither can plants. A fertilization plan is based on a soil analysis and the specific needs of the turf grass. Remember that various elements are washed away during the year or are consumed by the grass.|
|The kind and amount of fertilization depends on different aspects: grass species and cultivars (the mixture), purpose of the turf (golf, landscape, football, rugby, …), soil texture, organic matter content (%).
When overseeding, it is more benefi cial to the emerging new seedlings to apply fertiliser after germination rather than applying a pre-seed fertiliser. This may help to reduce the competition from the existing plants in the sod (especially undesirable grasses) and will assist establishment.
|Guidelines for turf nutrition
The table below shows the % of the total N P K, to be applied to the different species during the year in the specific climate zone for top quality of lawn (approximately -g/sqm-: N =15; P = 5; K = 15) The total aplications is split in threefour applications due to the use of CRF (Control release fertilizers) or SRF (Slow release fertilizers) or OF (organic fertilizers with high N content) If ready-soluble fertilizers are used, the application of N has to be split in 5-6 applications.
