<p>In order to eliminate the phosphorus fixation by precipitation and adsorption, increasing the use of phosphorus element in agricultural cultures, comprising a set of procedures to create a particular protection over the phosphorus granule (A) which is formed by Simple Superphosphate, Triple Superphosphast or mono ammonium phosphate (A), coated with polymer layers (B). These polymer layers applied individually, where the spraying operations are cumulative, it is to say, each new polymer spraying is made over the previous condition unitl reaching the desired phosphorus granule (A), representing a 50%-reduction of phosphorus amount applied to soil, also reducing the losses by adsorption.</p> |
