Some soils are well-drained, others easily waterlogged. As rain falls on the turf some evaporates, some may run off and the rest passes into the ground to become soil water. Some of this is absorbed by the plants' roots and is passed back into the atmosphere by transpiration. The rest passes on down until it reaches the level of the water table or an impermeable layer of soil or rock strata. It then commences to form a water table.
Water table rises during the winter and falls during the summer.
Sandstone is porous and these types or soil are naturally well-drained. A high water table limits the range of roots. Can show drought conditions quicker in the summer. The reduction of the height of the water table if closer than 2 feet to the soil surface will enable grass roots to reach their maximum depth. In turn, this improves aeration and mechanical equipment can be used to assist this.
