|Benefits of aerification|
There are several reasons why it is important to aerify greens on a regular basis. First and foremost is that it alleviates compaction and loosens the soil for better water infiltration and air exchange. Secondly it helps the soil to "breath" allowing it to expel harmful gases caused by decomposition. Additionally, aerification removes dead plant and excessive organic matter otherwise known as thatch. Thatch can greatly reduce water infiltration and gas exchange while also providing a breeding ground for disease pathogens.
