“We sprinkled vegetable compost in the garden,” wrote grape grower and winemaker Luca Ferraro on the Bele Casel Facebook last week. “We hardly had to wait for the results. There is already a tide of earthworms that help to make the soil more fertile.”
Lumbricus terrestris is their Latin name. The common earthworm.
“For millions of years,” wrote Jen Fong and Paula Hewitt on the Cornell University Department of Crop and Soil Sciences website, “worms have been hard at work breaking down organic materials and returning nutrients to the soil.”
“Worm composting is using worms to recycle food scraps and other organic material into a valuable soil amendment called vermicompost, or worm compost. Worms eat food scraps, which become compost as they pass through the worm’s body. Compost exits the worm through its tail end. This compost can then be used to grow plants. To understand why vermicompost is good for plants, remember that the worms are eating nutrient-rich fruit and vegetable scraps, and turning them into nutrient-rich compost.”
