Description
Die Anwendung des salpetersauren Harnstoffs, der sich: bei einer großen Reihe·von Vegetationsversuchen als ein ausgezeichnetes Düngemittel erwiesen hat, stößt im der landwirtschaftlichen Praxis auf große Hindernisse. Da nämlidh der salpetersaure Harnstoff eine nur sehr lockere Verbindung der Salpetersäure mit dem Harnstoff darstellt, so dissoziert er beim Zusammenkommen mitThe use of nitric urea, which is: in a large number of · of Vegetation trials have proven to be an excellent fertilizer, comes across in the agricultural Practice on major obstacles. There namely the nitric acid urea represents only a very loose connection between nitric acid and urea, so he dissociates when coming together
ίο Wasser sofort fast vollständig. Er wirkt infolgedessen stark ätzend und ruft, besonders leicht auf kalkarmen Böden uodi bei Verwendung als Kopfdünger, Schädigung der Pflanzen hervor. Aus demselben Grunde können aber auch bei Menschen und Vieh Schäden herbeigeführt werden, weil der salpetersaure Harnstoff beim Ausstreuen stark stäubt.ίο Almost all of the water immediately. It acts consequently highly corrosive and causes uodi, particularly easily on soils poor in lime Use as top fertilizer, damage the plants. But for the same reason it can also be done with humans and livestock Damage is caused because the nitric acid urea is strong when sprinkled dusts.
Die vorliegende Erfindung beseitigt diese Nachteile dadurch, daß nach ihr der salpetersäure Harnstoff in Mischung mit basischen Stoffen zur Verwendung gelangt. Von letzteren werden mehr als die zur Neutralisation der vorhandenen Salpetersäure nötige Mengen angewendet, um die Entstehung stark hygroskopischer Mischungen zu vermeiden. The present invention overcomes these disadvantages by adding nitric acid after it Urea is used in a mixture with basic substances. Of the latter, more than those are used for neutralization The necessary amounts of the nitric acid present are used to avoid the formation of highly hygroscopic mixtures.
Wird nämlich dem salpetersauren Harnstoff nur so viel oder noch weniger von z. B. Kalziumkarbonat zugesetzt, als zur Bindung der vorhandenen Salpetersäure notwendig ist, so erhält man ein Produkt, das beim Ausbreiten an der Luft schnell Wasser anzieht. Nimmt man das zweifache dieser Menge, so ist die Wasseramziebung nur gering, bei der dreifachen Menge erhält man bereits ein Produkt, . das dauernd gut streubar1; bleibt. In der gleichen Weise wie Kalziumkarbonat können auch andere säurebindende Stoffe, wie Kalziumoxyd, Magnesiumoxyd, Magnesiumkarbonat oder Gemische dieser Stoffe,benutzt werden. Es ist nicht erforderlich1, diese Stoffe in reiner Form zu verwenden; sie können auch in der Form angewandt werden, wie sie in natürlich vorkommenden Mergeln, Kalken und Dolomiten auftreten.Namely, if the nitric acid urea only as much or even less of z. B. calcium carbonate added, as is necessary to bind the existing nitric acid, the result is a product that quickly attracts water when spreading in the air. If you take twice this amount, the water absorption is only slight, with three times the amount you already get a product,. that is always easy to spread 1; remain. In the same way as calcium carbonate, other acid-binding substances such as calcium oxide, magnesium oxide, magnesium carbonate or mixtures of these substances can also be used. It is not necessary 1 to use these substances in their pure form; they can also be used in the form in which they occur in naturally occurring marls, limes and dolomites.
