Due to differences in formulation soil wetting agents differ in their effects on water infiltration, retention, and ability to reduce surface tension. For example, recent wetting agent trials have shown that there a big differences in their ability to retain soil moisture, effects on surface hardness, disease incidence, and turf quality.
