Process to obtain granule of urea with gradual release (L.G.U.) in soil and resultant product, in order to eliminate leaching and volatilization, increasing the use of urea element in agricultural cultures, comprising a set of procedures to create a particular protection over the urea granule (A), which is coated with four different polymer layers (B). Being individually applied in cumulative spraying operations, it is to say, each new polymer spraying is added to the previous coating until the desired urea granule (A), representing a 50%-reduction of urea amount applied to soil, also reducing losses by volatilization or leaching.
