Only 47% of the total fertilizer nitrogen applied to the environment is taken up by the plants whereas approximately 40% of the total fertilizer nitrogen lost to the environment reverts back into unreactive atmospheric dinitrogen that greatly affects the global nitrogen cycle including increased energy consumption for NH₃ synthesis, as well as accumulation of nitrates in drinking water. In this letter, we provide a mechanochemical method of inorganic magnesium and calcium salt–urea ionic cocrystal synthesis to obtain enhanced stability nitrogen fertilizers. The solvent-free mechanochemical synthesis presented can result in a greater manufacturing process sustainability by reducing or eliminating the need for solution handling and evaporation. NH₃ emission testing suggests that urea ionic cocrystals are capable of decreasing NH₃ emissions to the environment when compared to pure urea, thus providing implications for a sustainable global solution to the management of the nitrogen cycle.

镁和钙盐-尿素离子共晶肥料的机械合成，用于改善氮素管理

植物仅吸收了施加到环境中的总肥料氮中的47％，而损失到环境中的总肥料氮中约有40％转化为未反应的大气二氮，这极大地影响了全球氮循环，包括增加了NH的能源消耗。₃合成以及饮用水中硝酸盐的积累。在这封信中，我们提供了一种无机镁和钙盐-脲离子共晶合成的机械化学方法，以获得稳定性更高的氮肥。所提出的无溶剂机械化学合成可通过减少或消除对溶液处理和蒸发的需求来提高制造工艺的可持续性。NH ₃排放测试表明，与纯尿素相比，尿素离子共晶体能够减少向环境中排放的NH ₃，从而为氮循环管理的可持续全球解决方案提供了启示。
