Organic Gardening: Significance of Soil Food Web

The success of organic gardening lies in the quality of soil. Soil is constituted of various communities of organisms, right from cell bacteria and fungi, protozoa and algae to something which is more complex micro-arthropods, nematodes and the ones that are visible to the human eyes like insects, earthworms and vertebrates. All such organisms work on the garden soil to keep the soil healthy. They eat up the organic matter and move through the soil while depositing the castings in order to add nutrients to be fed by the plants. The process of tunneling improves the health of the soil, till the soil perfectly creates spaces to allow water and air to pass through. This entire mechanism improves the structure of the soil. Apart from adding nutrients, the food web keeps all the organisms that grow in the soil healthy. Healthy organisms can also safeguard the soil and the entire garden from diseases and unwanted pests. Thus, it is important to keep the community of organisms in the soil.
