  Aus Superphosphat und kieselsäurehaltigen Materialien bestehender   Pflanzennährstoff.   



   Gegenstand des Stammpatentes Nr. 125177 ist ein   kieselsäurehaltiges Phosphatdüngemittel,   welches aus einem Gemisch von trockenem, streufähigem   Superphosphat   und einer bis zu 10% betragenden Menge einer   schwerlöslichen,   adsorptionsfähigen   Kieselsäuremodifikation,   wie Kieselgur, Tripel, Polierschiefer, Kieselsinter usw. besteht. 



   Die vorliegende Erfindung stellt eine weitere Ausbildung des Gegenstandes des Stammpatentes Nr. 125177 insoferne dar, als das Düngemittel auch noch Kalisalz und stickstoffhaltige Substanzen oder letztere allein enthält. 



   Das Ammonsulfat muss im Boden durch die bekannten Vorgänge der Nitrifikation erst in die pflanzenaufnahmefähige Salpeterform umgewandelt werden, während der Pflanze im Superphosphat und Kalisalz sofort verwertbare Nährstoffe zur Verfügung stehen. Dies bedingt beispielsweise bei gleichzeitiger Ausstreuung von Superphosphat, Ammonsulfat und Kalisalz eine einseitige und unzweckmässige Ernährung der Pflanzen, ein Umstand der durch die Zugabe eines schwerlöslichen Adsorptionsmittels beseitigt wird. Das Adsorptionsmittel hält insbesondere das Superphosphat im Anfangsstadium der Pflanzenentwicklung mechanisch fest, so dass dieser Nährstoff nicht im Übermass von der Pflanze aufgenommen und auch nicht so schnell durch Umsetzung im Boden in für die Pflanze nicht verwertbare unlösliche Formen übergeführt werden kann.

   Der Pflanze steht das Superphosphat also nicht nur zu Anfang in dosiertem Masse zur Verfügung, sondern auch noch späterhin, wenn auch das Ammonsulfat in verwertbare Salpeterformen umgewandelt ist. 



   Beispiel 1 : Zu einem Mischdünger, Superphosphat, Ammonsulfat und Kalisalz werden 3-5% Adsorptionsmittel, z. B. Kieselgur, zugegeben. 



   Beispiel 2 : Superphosphat wird mit 3-5% Kieselgur innig vermischt. Dem Gemisch werden Ammonsulfat und Kalisalz oder nur ersteres allein einverleibt.

  A plant nutrient made from superphosphate and materials containing silica.



   The subject of the parent patent No. 125177 is a silicic acid-containing phosphate fertilizer, which consists of a mixture of dry, spreadable superphosphate and an amount of up to 10% of a poorly soluble, adsorptive silicic acid modification such as kieselguhr, triple, polishing slate, silica sinter, etc.



   The present invention represents a further development of the subject matter of the parent patent no. 125177 insofar as the fertilizer also contains potassium salt and nitrogenous substances or the latter alone.



   The ammonium sulphate in the soil must first be converted into the plant-absorbable form of nitric by the well-known processes of nitrification, while the plant in the superphosphate and potassium salt is immediately available nutrients. For example, when superphosphate, ammonium sulfate and potassium salt are scattered at the same time, this results in a one-sided and inexpedient nutrition of the plants, a circumstance which is eliminated by the addition of a poorly soluble adsorbent. In particular, the adsorbent holds the superphosphate mechanically in the early stages of plant development, so that this nutrient cannot be absorbed in excess by the plant and cannot be converted so quickly into insoluble forms that cannot be used by the plant through conversion in the soil.

   The superphosphate is not only available to the plant in dosed quantities at the beginning, but also later, when the ammonium sulfate has also been converted into usable forms of saltpetre.



   Example 1: To a mixed fertilizer, superphosphate, ammonium sulfate and potassium salt, 3-5% adsorbent, e.g. B. kieselguhr added.



   Example 2: Superphosphate is intimately mixed with 3-5% kieselguhr. Ammonium sulfate and potassium salt or just the former alone are incorporated into the mixture.
