The perspectivity of attracting ammoniated
superphosphate based on phosphorites with content of
P2O5 is not less than 19 % as the main phosphate shell
component for the encapsulation of urea have been
substantiated. The peculiarities of the kinetics of
phosphorus decomposition with the formation of
ammoniated superphosphate have been established.
Examples of its use as a phosphate shell are given. The
ecological feasibility of using it as a phosphate shell is shown.
