optein, the magnesium thermo phosphate that has balanced macronutrients and micronutrients in silicates in 100% of the particles, has arrived to guarantee uniform application with the aim of segregation. ideal product for situations where it is objectified the elevation of phosphorus levels and the construction of soil fertility, with an increase in productivity and quality of the harvested products. benefits as a result of its manufacturing process, the optein magnesium thermo phosphate presents some characteristics that increase its agronomic efficiency in relation to the other sources of phosphorus.   manufacturing process optein magnesium thermo phosphate is a phosphate fertilizer obtained through the melting process of phosphate rock with magnesium silicate, limestone and micronutrient sources (boron, copper, manganese and zinc),   resulting in a nutritionally balanced product with high agronomic efficiency. the preheated phosphate material, together with the limestone and the micronutrient-containing minerals, are added with hot liquid magnesium silicate. due to the metallurgical route of iron-nickel production, the magnesium silicate obtained in the process is poured at the average temperature of 1600 ºc for the electric furnace that produces the thermo fertilizer and, with this, the enormous amount of calorific energy contained in the source material of silicon and magnesium is integrated into the system, requiring only the addition of energy so that the mixture reaches its melting point, at 1, 500 ºc. the resulting molten material is subjected to a water jet thermal shock for solidification, whose volume and pressure define the desired particle size. the semi-finished product follows for drying and milling, where it is subsequently bagged and marketed. .
