Many times, when installing sod, seeding a new lawn, or installing a new bed, many people’s first thought is to bring in topsoil. By itself, topsoil might be lacking several of the key components to building a healthy root system for your lawn and plants. Having a deficiency in vital nutrients such as Nitrogen, Phosphorous, Potassium, and other trace minerals, as well as the organic matter that is lost over time. So how is this problem resolved? Compost. The addition of compost to topsoil improves the moisture retention and structure of the soil, key benefits missing topsoil alone. A compost-enriched soil has the ability to store nutrients for the plant to use, whereas in topsoil, the nutrients will leach away with each rainfall or watering. Another key benefit of compost-enriched soil is the Mycorrhizae that are now encouraged to flourish in the soil. Mycorrhizae is a beneficial fungus that increases a plant’s ability to not only withstand drought and temperature changes, but also helps protect against soil pathogens, improves mineral uptake, and helps nitrogen transfer in the soil.
