Oxygen is essential for the roots of grass to breathe and grow strong enough to support healthy lawns. But according to the Center for Agriculture, Food and the Environment at the University of Massachusetts Amherst, compacted soil can produce a decrease in oxygen content that can make it hard for roots to thrive. Soil compaction can result from a number of activities, including walking on grass or driving or parking vehicles on grass. When soil is compacted, it breaks into small particles that reduce the amount of pore space in the soil. That makes it hard for water, oxygen, and nutrients to get through, threatening the strength of the roots and putting the grass in jeopardy. Aerating a lawn can help homeowners foster strong root growth and healthy grass. When to aerate may be contingent upon local climate, so homeowners who suspect the soil in their yards is compact should consult with a local landscaping professional to determine the best time to aerate their lawns.
