Abstract: Herbicidal compositions contain glyphosate (N-phosphonomethylglycine) and a surfactant of formula: ##STR1## in which R.sup.1 and R.sup.2, are each independently selected from the group consisting of hydrogen and C.sub.1-4 alkyl; R.sup.3 is selected from the group consisting of hydrogen, C.sub.-4 alkyl and aryl; Ar is an alkyl-substituted aryl system wherein each alkyl substituent contains from 4 to 12 carbon atoms; n is an integer from 1 to 4; and X is a halide, ethylsulphate, methylsulphate, dimethylphosphate, polyalkoxyphosphate, lactate or acetate.

Abstract: Turf or soil is treated to alleviate drought stress and soil capping and to improve soil water conservation by applying directly to the turf or soil a composition comprising an organosilicone and a polyalkylene oxide surfactant.
