Soil aeration is the process of allowing air to enter the soil, which is essential for healthy plant growth. It helps improve the availability of oxygen to plant roots and beneficial microorganisms, promoting better nutrient uptake and overall soil health. Aeration can be achieved through natural processes, such as earthworm activity, or through mechanical methods like using a core aerator. Proper soil aeration also helps reduce soil compaction, which can hinder root development and water infiltration. By creating small holes or channels in the soil, aeration allows for better drainage and reduces the risk of waterlogging, ensuring that plants receive the right balance of moisture and air.
