Of all the critters that can be found in a garden I’m always glad to see a worm. The most obvious benefit comes from their constant tilling of the soil providing aeration and improving the percolation of water throughout the root zone. But having been trained in the scientific method at the University of Arizona I’m also glad to find data that supports my beliefs.
Last fall I received an email from plant pathologist at Cornell University. Ms Allison Jack, a PhD candidate, forwarded studies on the use of vermicompost, also known as worm castings, in disease control and plant growth. While scientific papers can be tedious for the layperson, if you’re interested I’ll gladly forward these studies to you. Just send a request to OzarkAggie@gmail.com and I’ll reply with the articles attached.
Fortunately Allison has published an award-winning video that provides an overview of vermicomposting, and how worm castings provide both a nutritional benefit and disease protection for plants. It’s definitely worth a watch.
