摘要：
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) R.sub.1 . . . R.sub.3 '=NH.sub.2 or(2) R.sub.1 '=R.sub.2 '=R.sub.3 '=R.sub.2 =R.sub.3 =NH.sub.2 and R.sub.1 =OC.sub.6 H.sub.5 or(3) R.sub.1 '=R.sub.2 '=R.sub.3 '=R.sub.3 =NH.sub.2 and R.sub.1 =R.sub.2 =OC.sub.6 H.sub.5 or(4) R.sub.1 '=R.sub.2 '=R.sub.3 '=NH.sub.2 and R.sub.1 =R.sub.2 =R.sub.3 =OC.sub.6 H.sub.5.
