Abstract
A process is realized by means of consistent introduction of carbamide resin and double superphosphate. For the purpose of increasing the quality and reliability of neutralization at simultaneous improvement of agrochemical properties of cured solution, before the introduction into the worked-out drilling mud the carbamide resin is additionally intermixed with tetraethylenepentamine and dimonoethanolamine salt of biphosphonate acids.
