Description

Mischdünger In dem Hauptpatent ist ein Mischdünger beschrieben, der aus Kaliumbicarbonat oder seinem Doppelsalz mit Magnesiumcarbonat, dem Engelschen Salz, besteht. und den den Boden sauer machenden Ammoniumsalzen, wie dem Sulfat, Chlorid und Phosphat.Mixed fertilizer The main patent describes a mixed fertilizer that made of potassium bicarbonate or its double salt with magnesium carbonate, the Engelschen Salt. and the ammonium salts that acidify the soil, such as sulphate, Chloride and phosphate.

Wird aus dem Kaliumbicarbonat und den Ammonsalzen, z. B. dem Ammonsulfat, eine Mischung hergestellt, in der das Verhältnis von Stickstoff zu Kali das bei Mischdüngern übliche ist. so reicht die Menge des Kaliumbicarbonats nicht zu einer vollkommenen Neutralisierung dieses physiologisch sauren Düngemittels iin Boden aus. Wohl aber wird dieser Effekt erreicht, wenn man das Engelsche Salz verwendet; nur hat dieses den Nachteil, bei der erforderlichen völligen Trocknung leicht einen gewissen Teil der Kohlensäure abzugeben, so daß ein Produkt resultiert, welches, wegen seines Gehaltes an Kaliumcarbonat, mit Ammonsalzen beim Lagern Ammoniak entwickelt.Is made from the potassium bicarbonate and the ammonium salts, e.g. B. the ammonium sulfate, a mixture is made in which the ratio of nitrogen to potash contributes to this Mixed fertilizers are common. so the amount of potassium bicarbonate is not enough for one complete neutralization of this physiologically acidic fertilizer in the soil the end. However, this effect is achieved if one uses Engel's salt; only this has the disadvantage that, when complete drying is required, it can easily become one to give off certain part of the carbonic acid, so that a product results which, because of its potassium carbonate content, ammonia developed with ammonium salts during storage.

Diesen Übelstand kann man dadurch umgehen, daß man, statt das Doppelsalz von halnumbicarbonat und Magnesiumcarbonattrihydrat, das Engelsche Salz, für die Herstellung des Mischdüngers zu benutzen, Kaliumbicarbonat im Gemisch mit gesondert hergestelltem Magnesiumcarbonattriliydrat verwendet. Man kann dann die Menge des zugesetzten Magnesiumcarbonattrihydrats gerade so bemessen, daß auch bei Innehaltung des richtigen Verhältnisses von Kali und Stickstoff jede Versäuerung des Bodens durch den Dünger verhindert wird.One can avoid this problem by, instead of the double salt of halibicarbonate and magnesium carbonate trihydrate, Engel's salt, for the To use the preparation of the mixed fertilizer, potassium bicarbonate mixed with separately produced magnesium carbonate trilydrate is used. You can then change the amount of added magnesium carbonate trihydrate just sized so that even when pausing the correct ratio of potash and nitrogen, any acidification of the soil is prevented by the fertilizer.

Überraschenderweise ergab sich aber, daß auch die sogenannten basischen Magnesiunicarbonate ini Gemisch mit Ammonsulfat, Ammonchlorid und Ammonphosphat, auch in Gegenwart @-on haliumbicarbonat, haltbare Produkte ergeben, also trotz der Basizität des Magnesiumcarbonats nicht die geringste Am,noniakentwicklung eintritt.Surprisingly, however, it was found that the so-called basic Magnesium carbonate in a mixture with ammonium sulfate, ammonium chloride and ammonium phosphate, Even in the presence of @ -on halium bicarbonate, durable products result, so in spite of the The basicity of the magnesium carbonate is not even the slightest amount of ammonia.

Beispielsweise kann man ?o Teile Amnionsulfat, to Teile Kaliumbicarbonat und io Teile basisches Magnesiumcarbonat zur Herstellung eines solchen nicht siiuernden Düngers miteinander mischen.For example, one can use? O parts amniotic sulfate, to parts potassium bicarbonate and 10 parts of basic magnesium carbonate for the production of such a non-acidifying one Mix the fertilizer together.
