Dry Patch

An irregular area of turf which has become drought stressed and is difficult to rewet due to the presence of a water repellent agent within the soil, typically within the top 50mm of the surface. Beneath this affected area there is often a dry area which can be dust dry with very limited root penetration, or no roots. Where the sward is patchy in small affected areas, this might be termed Localised Dry Patch (LDP), but there is no consensus on this distinguishing nuance.
