Abstract

Tests show that 2,2,4,4,6,6-hexaaminocyclotriphosphazatriene, 2-phenoxy-2,4,4,6,6-pentaaminocyclotriphosphazatriene, 2,4-diphenoxy-2,4,6,6-tetraaminocyclotriphosphazatriene and 2,4,6-triphenoxy-2,4,6-triaminocyclotriphosphazatriene (also frequently called phosphonitrilic derivatives) of the formula ##STR1## are highly effective inhibitors of urease activity in agricultural soil systems wherein
(1) R1 . . . R3 '=NH2 or
(2) R1 '=R2 '=R3 '=R2 =R3 =NH2 and R1 =OC6 H5 or
(3) R1 '=R2 '=R3 '=R3 =NH2 and R1 =R2 =OC6 H5 or
(4) R1 '=R2 '=R3 '=NH2 and R1 =R2 =R3 =OC6 H5
The above-mentioned compounds and mixtures of the compounds show sustained inhibition of the soil urease activity for periods of at least 21 days.
