    • In particular to improve the physico-mechanical properties of granular fertilisers and in order to increase the efficiency of the application of alkaline, alkaline earth-elements and group IV elements, the invention provides a method for producing granular fertilisers comprising at least one structural compound based on at least one salt with the steps of disposing of at least one salt comprising nitrogen, humidifying the at least one salt, mixing the at least one humidified salt with at least one substance comprising at least one alkaline and/or alkaline-earth element and/or at least one element of the forth period of group IV, producing a granular fertiliser by granulation of the mixture, and cooling the granular fertiliser. The invention further provides a granular fertiliser comprising nitrogen and having a ph in the range of 3 = pH = 7. The granular fertiliser shows a strength σ of σ = 3 Mpa and an entire amount c sc of at least one structural compound with c sc = 50 wt. -%.
    • 特别是为了提高颗粒肥料的物理力学性能,为了提高碱土金属元素和Ⅳ族元素的使用效率,本发明提供了一种生产颗粒肥料的方法,该方法包括至少一种基于 至少一种盐,其步骤是处置至少一种包含氮的盐,加湿至少一种盐,将至少一种加湿盐与至少一种包含至少一种碱土金属和/或碱土元素的物质混合,以及 /或组IV的第四周期的至少一个元素,通过混合物的制粒产生颗粒肥料,并冷却颗粒肥料。 本发明还提供了一种包含氮气并且具有3 = pH = 7的ph的颗粒肥料。颗粒肥料显示sigma = 3Mpa的强度sigma和csc = 50的至少一种结构化合物的总量csc 重量。 - %。
