Also used in broadacre furrow applications for cropping in non-wetting sands. Agricultural Water Management | Hydrasoil will "harvest" and direct available moisture and rainfall to the root areas.


Hydrasoil Technical Information

What is the cause of "Dry Patch"?

"Dry Patch" is a physiological condition that shows up in turf as an area of dryness or turf discoloration during hot dry periods. It is directly associated with a shallow root system caused by factors such as compaction, layering, pests, diseases, or over-use of chemicals. However, the most common cause in turf is an area of water repellency either in the thatch or within the sand profile.


Water repellent soils are a result of non-wetting organic compounds coating soil particles over a period of time.

Sandy soils are very prone to water repellency due to three reasons:

  1. The rough and very low specific surface area of sand particles, makes sand more easily coated by organic compounds as they leach through the profile;
  2. Sandy soil favours the growth of fungi and fungal hyphae. Fungi feed on organic matter leaving behind waxes, lignins and organic acids like fulvic acid. Fulvic acids, one of the major by-products from microbial activity, are a major source of water repellency;
  3. Remnant fungal hyphae from Basidiomycetes sp (Fairy ring) which are a major source of water repellent organic matter favour dry sandy soils;
  4. Sandy soil dry out easily and once the sand particles are coated with organic acids and dry-out, the sand particles become non-wetting.

There are some cultural practices that can be used to reduce the on-set of non-wetting conditions. However in turf situations, it is inevitable that it will occur.


Cultural practices used to reduce "Dry Patch"

  1. Use low volumes of organic amendments;
  2. Reduce the build up of organic matter by managing your thatch level with regular grooming and dethatching;
  3. Light coring of the surface to allow more uniform re-wetting of the profile;
  4. Irrigate over longer cycles to flush the profile and prevent shallow root development;
  5. Dilute the level of non-wetting sand by topdressing or dusting with new sand on a regular basis. This also slows down the accumulation of thatch; AND
  6. Regular application of a soil wetting agent like Hydrasoil.


How safe is Agricultural Water Management | Hydrasoil to Plants?

Agricultural Water Management | Hydrasoil® has been tested for its safety to plants and various grass species and found to be very safe.

Two grass species were tested to demonstrate the safety of Agricultural Water Management | Hydrasoil® on a phytotoxicity rating scale of 0-100 (0-no damage).

1 day after treatment, both Browntop Bent and Wintergreen Couch at Hydrasoil dose rates of x1, x2 and x5 showed 0-level damage.

Furthermore, 7 days after treatment, both Browntop Bent and Wintergreen Couch at Hydrasoil dose rates of x1, x2 and x5 also showed 0-level damage.
