Detergent works as surfactant.Surfactants reduce the surface tension of water by adsorbing at the liquid-gas interfaceThe main barrier to water movement into the seed is a waxy layer, called the cuticle, that covers the entire plant surface. Its purpose is to prevent water loss. fertilizers formulated or applied with right amount surfactants reduce the surface tension of water and allow for more effective movement of the water and nutrients through the cuticle.
