The disclosure provides an electromagnetic ionic liquid, which consists of ammonia water, diluent, EWT electronic water and macromolecular complex. The four components are mixed evenly at normal temperature and pressure in a certain proportion to prepare the electromagnetic ionic liquid. The electromagnetic ionic liquid can be used for extracting struvite from seawater, salt water or brine, which improves quality of the struvite, facilitates its industrial production and improves yield of struvite products. In addition, with the electromagnetic ionic liquid, elements required for crop growth and dozens of types of trace elements can be captured in the precipitate, which has great social and economic value for mass production, popularization and application of the struvite.

The present invention refers to an industrial process for obtaining an agricultural composition formed by association of one or more species of Bacillus spp., of Lactobacillus spp. and of Pseudomonas, the process for induction of exudates/metabolites, as well as the application thereof in the manufacture and in the increase of the efficiency of phosphate fertilizers of mineral, organomineral and organic origin. Surprisingly, the agricultural composition used in the fertilization industry increases the availability of macro and micronutrients to the plants with agricultural interest, such as soy and corn. Finally, both the use of the agricultural composition in the fertilizers industry as the application of the product in the field potentialize the greater availability of essential nutrients for the development of the cultures.
