Fertilizer application proves best immediately before and during the period of intensive growth of the crops. The fertilizer 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.


4 -5 kg/ha of fertilizer diluted with water in the amount of 200-800 l/ha based on the sprayer type and condition of the plants. In perennial crops, repeated application is recommended after 14-21 days. Multiple application and higher concentration of the fertilizer improve the health status of the plants. As for winter rape, spring dose division into 2×2 kg/ha is recommended during the vegetation period. Mix the fertilizer thoroughly before filling in the sprayer. One-time overdosage of the fertilizer is not phytotoxic.


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