Abstract

The mixt. has a particle size of 0.5 mm and contains 38-42% SiO2; 10-12% Fe2O3, 10-12% Al2O3, 9-11% CaO, 15-25% MgO; 0-1% MnO, 0.5-3% K2O and 0.5-3% P2O5. >=1/3 of the pref. fertiliser has a particle size of 0.1 mm. The Al2O3 is pref. largely montmorillonite. The pref. mineral fertiliser is obtd. by finely milling a basalt with 40-50% SiO2, homogeneously mixed with finely milled MgO. The fertiliser increases soil fertility considerably more than know products.

Description

N a t u r m i n e r a l d ü n g e r Die Erfindung betrifft einen Naturmineraldünger. Der Erfindung liegt die Aufgabe zugrunde, einen Dünger herzustellen, der in erheblich grösserem Masse als bisherige, bekannte Naturmineraldünger die Fruchtbarkeit der Böden vergrössert. N a t u r m i n e r a l d u n g e r The invention relates to a Natural mineral fertilizers. The invention is based on the object of producing a fertilizer, the well-known natural mineral fertilizer to a much greater extent than previous Soil fertility increased.

Gemäss der Erfindung hat der Naturmineraldünger folgende Zusammensetzung: SiO2 38 - 42 a Fe2O3 10 - 12 % Al2O3 10 - 12 % Cao 9 - 11 % MgO 15 - 25 % IInO O - 1 S K2O 0,5 - 3 % P20 0,5 - 3 ß und eine Körnung von weniger als 0,5 mm. Vorzugsweise besteht die Tonerde (Al2O3) zum überwiegenden Teil aus Montmorillonit.According to the invention, the natural mineral fertilizer has the following composition: SiO2 38 - 42 a Fe2O3 10 - 12% Al2O3 10 - 12% Cao 9 - 11% MgO 15 - 25% IInO O - 1 S K2O 0.5 - 3% P20 0.5 - 3 ß and a grain size of less than 0.5 mm. Preferably the alumina (Al2O3) consists mainly of montmorillonite.

Die Körnung ist vorzugsweise sehr fein und soll möglichst bei mindestens einen Drittel des Düngers kleiner sein als 0,1 mm.The grain size is preferably very fine and should, if possible, be at least a third of the fertilizer should be smaller than 0.1 mm.

Vorzugsweise wird der Naturmineraldünger in der Weise hergestellt, dass Basalt mit etwa 40 - 50% Siliziumoxyd auf die Korngrösse gemahlen wird, dass ferner liagnesiumoxyd fein gemahlen wird und diese beiden komponenten dann innig miteinander vermischt werden. In dieser Weise hergestellte ITaturmineraldünger enthalten beispielsweise 40,15 % Kieselsäure 11,89 % Eisenoxyd 11,98 % Tonerde 9,48 70 Kalziumoxyd 23,50 $ Magnesiumoxyd 0,23 % Mangan 0,82 % Kaliumoxyd 0,67 % Phosphorpentoxyd 1,28 % Spurenelemente und Kristallwasser.The natural mineral fertilizer is preferably produced in such a way that that basalt with about 40 - 50% silicon oxide is ground to the grain size, that Furthermore, liagnesium oxide is finely ground and these two components are then intimately ground mixed together will. Natural mineral fertilizers produced in this way contain 40.15% silica 11.89% iron oxide 11.98% alumina 9.48 70 calcium oxide $ 23.50 magnesium oxide 0.23% manganese 0.82% potassium oxide 0.67% phosphorus pentoxide 1.28% trace elements and crystal water.
