Why Soil Life Matters
It is often forgotten soil maintains life within it as well as on it. Soil organisms, such as bacteria and fungi, work to help soil maintain its structure, function as a water filter, and provide plants with everything they need to grow. In fact, plant roots will interact with fungus and soil bacteria and to form a symbiotic relationship in the soil. All of this takes place within the top foot, or so, of soil in what is called a rhizosphere. The microorganisms within a rhizosphere can be beneficial to plant growth and productivity. Organisms that depend on the soil are also beneficial to plants such as worms which help to aerate soil and transport nutrients down to where roots can better obtain them.
