Ferro Top® is a special iron fertilizer with high contents of potash and magnesium as well as manganese to promote the quality, resistance and colour of plants. In combination with the low nitrogen content, grasses can form important amino acids, enzymes and proteins. The result is improved chlorophyll formation and energy utilization. The turf is better protected against weather influences and fungal diseases. Ferro Top® displaces moss and protects against new settlement. This is particularly important in winter to spring.
Thanks to its even granulation, Ferro Top® can be applied easily with spreaders or by hand. Nutrient distribution is even as every granule contains all nutrients. Application is possible during the whole vegetation period. Watering-in (minimum 5 mm) after application is strongly recommended!
