Using Compost and Mulch
Compost confers many chemical, physical, and biological benefits to the soil. First, compost supplies nutrients essential to plant growth. Compost contains small amounts of nitrogen, which is often the limiting soil element for optimum plant growth. For more information about compost and mulch, see Benefits of Compost and What is Compost and Mulch.
