Why Are Earthworms Important For My Soil?Earthworms are important for healthy soils. They love to eat organic materials within the soil, so if you find them, this means you probably have a good amount of available organic materials. Earthworms also help to maintain healthy soil, since they will migrate to healthy soils where organic materials are abundant. They will tunnel within the soil, devouring the organic materials, and leaving their castings (worm poo). Earthworm castings can contain as much as 10 times the amount of plant-available nutrients as the original soil. There are also microorganisms that are generated inside the different chambers of the earthworm's body. These microorganisms are then released into the soil adding more beneficial microorganisms. The earthworm tunnels help to aerate and loosen the soil. This will help plant roots to grow deeper in the soil, and allow beneficial microorganisms to breathe. Earthworms will aid in loosening compacted soils. The loosened soil also helps water to reach plant roots much easier, and create better overall water drainage.
How Do I Attract Earthworms To My Garden Soil?The best way to get earthworms tunneling in your soil is to add organic materials to the soil in the form of nutrient-rich compost. Try to avoid over tilling your soil as this can damage the "mini" eco-system within the soil, and hamper earthworm effectiveness. Also avoid using fertilizers high in nitrogen, and chemical pesticides. Earthworms can reproduce fairly quickly if they are not wiped out by the poisonous pesticides. Direct composting is a great way to attract earthworms to your garden soil. This methods works very well if you want to attract earthworms to a particular area of your vegetable garden. Although I have never tried this myself, I have seen gardeners introduce purchased red wiggler worms (the same worms used in worm composting) to their vegetable garden soil. They prepared the garden soil by spreading out compost or well-aged manure, and then release the worms to feast. Earthworms can be purchased at most fishing supply businesses, commonly called Nightcrawlers. Earthworms are rarely ever seen, but are an important part of your soil's health.
