   Die   düngende   Wirkung dea Kalksalpeters ist eine Nebenerscheinung die nicht den Erefindungs-Charakter bedingt, nicht der Grund für die technische Wirkung des Gegenstandes ist. 



   Man hat schon vorgeschlagen, einen aus   Thomasmehl   und schwefelsaurem Ammoniak   bestehenden Mischdünger z. B.   mit getrocknetem Carnallit   zu.   nischen, welcher ein Wasser leicht   anziehendes   Salz darstellt, wodurch das Entweichen von   Ammoniak   verhindert wurde. 
 EMI2.1 
 



   In vorliegendem Fall wird das Calciumcyanamid durch Zusatz des Wasser leicht anziehenden Mittels vor Zersetzung geschützt. Dieser Zusatz muss aber bei einer der Schmelzwärme dieses   Zusatzkörpers   entsprechenden Temperatur geschehen, um eine genügend innige Durchmischung zu erzielen und es findet ausserdem noch die Wirkung statt, dass das nach diesem Mischen zerkleinere Produkt beim Ausstreuen auf das Feld nicht stäubt.

   The fertilizing effect of the calcium nitrate is a side effect that does not determine the inventiveness, is not the reason for the technical effect of the object.



   It has already been proposed to use a mixed fertilizer consisting of Thomas flour and ammonia sulfuric acid, e.g. B. with dried carnallite. niche, which is a salt that easily attracts water, preventing ammonia from escaping.
 EMI2.1
 



   In the present case, the calcium cyanamide is protected from decomposition by adding the water-absorbing agent. However, this addition must take place at a temperature corresponding to the heat of fusion of this additional body in order to achieve a sufficiently intimate mixing and there is also the effect that the product, which is comminuted after this mixing, does not dust when it is scattered on the field.
