Topsoil contains different types of organic and inorganic particles, but humus is a essential component that gives it fertility and provides nutrients for plant growth. Ozone is not present in significant amounts in soil, freshly fallen leaves may contribute to the organic matter content in the soil, but they are not the only component, and aquatic plants are associated with wetlands and aquatic ecosystems, not typical topsoil environments.
