AmegA Sciences wetting agents are sold all over the world. The range comprises of turfgrass and media wetting agents in several formulations to give easy applications. All the wetting agents are based on new generation surfactant chemistry.
Dry Patch
Research worldwide has shown the initial cause of dry patch is the build up of naturally produced waxes and lipids around the sand/soil particles. When these coated sand/soil particles dry out they become hydrophobic (water-repellent) and the rootzone is unable to hold water. Dry patch usually appears during periods of dry weather as small isolated patches of thin, stressed water repellent turf. The symptoms can affect all turfgrass species but initially are more apparent on the shallower rooted species i.e. annual meadow grass where total die back of the plant can occur very quickly.
Beneath the surface in these affected areas the soil is extremely dry and will not easily re-wet. Research in the United Kingdom has shown that the build up of waxes and lipids around the sand/soil particles that cause dry patch are concentrated at the soil thatch interface and this area is referred to as the hydrophobic zone.
