Introducing the GLS Grassland subsoiler

The sub-surface shatter created by the GLS revitalises compacted sward, by improving drainage and root development, and allowing more air to get into the soil; resulting in increased fungal/bacterial activity in addition to enabling worm populations to flourish. The end result is a soil environment that is conducive to maximum grass growth and stronger plants that are better suited to withstand periods of prolonged rainfall or drought.
