Fertilization with 200 - 250 kg/ha calcium cyanamide Perlka® directly before sowing (no incorporation, no waiting time!) ensures ideal starting conditions for oil seed rape. The ammonium-based nitrogen effect and the highly reactive lime ensure rapid but not too rapid growth of the young rape plants. At the same time, the fertilizer shows quite a good side effect against slugs and slug eggs. Experience in recent years has also shown that such calcium cyanamide fertilization also significantly reduces the risk of early infections of club root. Also other crop-related diseases such as Phoma. Sclerotinia and Verticillium occur less frequently in fields fertilized with calcium cyanamide.
With modern seeders, positive effects can also be achieved with smaller quantities of fertiliser. With a fertiliser depot placement below the seed row, usually only 80 to 100 kg/ha of calcium cyanamide Perlka® are applied. It is important that the quantities of nitrogen applied in autumn are fully taken into account for spring fertilization. The total nitrogen expenditure does not increase. The healthier crops generally lead to higher yields, which means higher nitrogen depletion. The targeted application of calcium cyanamide fertilizer in rape therefore helps to avoid unnecessary surpluses in the N balance of rape by safeguarding yields.
Interested farmers are recommended to order calcium cyanamide Perlka® immediately from the trade in order to secure the favourable June price.
