What to do with clay soil.

Core aeration is a process that involves removing small plugs of soil from the lawn, which helps to improve air exchange, enhance root growth, and promote a healthier lawn. One of the significant benefits of aeration is the reduction of soil compaction, particularly in clay soils. Compacted soil can restrict root development and limit the access of nutrients and water to the grass, making it difficult for the lawn to thrive.
When clay soil is amended with gypsum and organic material during the top dressing process, several advantages arise. Gypsum helps to improve soil structure by promoting the aggregation of soil particles. This enhancement leads to better drainage and reduced runoff, which can lower the risk of waterlogging and promote deeper root growth. Additionally, gypsum can help to displace sodium ions in saline soils, further improving the soil's overall health.
Incorporating organic material, such as compost, provides essential nutrients that support microbial activity in the soil. This biological activity increases the soil's fertility, thereby fostering a vibrant and resilient lawn. Organic material also improves moisture retention while enhancing aeration, making it easier for roots to access water and nutrients.
Together, core aeration and the amendment of clay soil with gypsum and organic material during top dressing create an environment conducive to a robust lawn. This combination improves soil structure, enhances nutrient availability, promotes healthy root development, and ultimately leads to a lush, thriving landscape.
