Frequent foot traffic wears turf away because it compacts the soil, depriving grass roots of
oxygen. There are two ways to reduce soil compaction. The liquid way is to spray a product
containing humic acid on worn spots a couple of times a year. Humic acid loosens and conditions
packed soil, especially clay. The mechanical way is to use a spiking tool to punch holes in the
compacted area to allow oxygen to enter the soil.
