Range and method of use

FUMAG 6NK–Zn is foliar suspension fertilizer with curative effect, with optional removal of the latent as well as apparent zinc deficit, with concurrent magnesium, nitrogen and potassium supply. Magnesium represents a fundamental component of chlorophyll, which converts the energy of light to chemical energy and is a necessary nutrient for plant growth and development. Zinc is an important part of many enzymes, has an impact on formation of growth hormones and aminoacids metabolism. Zinc deficit is manifested in the youngest parts of plants by narrow, small leaves, frequently rolled up and short internodes. FUMAG 6NK–Zn is designated for treatment of the majority of kinds of grown annual and perennial crops. Preferential application based on demands for nutrients: for hop, winter rape, maize, potato and fruit trees.

Potassium K2O - 6 %
Nitrogen N - 6 %
Magnesium MgO - 12 %
Zinc Zn - 10 %

The advantage of this fertilizer consists in high and quick zinc supply, potentiated by its citrate form; gradual magnesium supply; high pH value; and increased resistance against fungal diseases. Upon determining magnesium or zinc deficit, the fertilizer can be applied immediately and treatment of the vegetation can be repeated after 10-14 days until the symptoms subside. Fertilizer application proves best in the majority of crops in the period of intensive growth. Repeated application after 7-21 days is recommended. Multiple application and higher concentration improve the health status of the plants. FUMAG 6NK–Zn can be applied together with nitrogen liquid fertilizers, for example, DAM 390, urea solution. Can be combined with the majority of plant protection products, upon consulting their manufacturers. Individual types of Fumag fertilizers can be mixed with each other. Should not be mixed with phosphorus-containing fertilizers.


Annual crops: 4-5 kg/ha.

Perennial crops: 4-5 kg/ha; repeated application after 14-21days is recommended.

Mix the fertilizer thoroughly before filling in the sprayer. Application in combination with the fertilizer DAM 390 and urea solution is not recommended when dew is present and under direct intensive sun light.


Store the fertilizer in original packaging and in a dry place under lock in temperatures between +5 to +25 °C.
