The benefits of using vermicompost

Vermicompost-- or compost made by worms-- is not only a great alternative to chemical fertilizers, it's also a better alternative to traditional compost. We've been using it in our yard and garden, and selling it to our customers, for years with amazing results.

But what are the actual benefits of vermicompost-- what's the science behind it? We've laid it out for you below:

What is vermicompost? Vermicompost-- or worm compost or worm casting or worm poop-- is what you get after worms consume organic matter and excrete it. As food passes through their digestive tract, worms secrete chemicals that break down organic matter into sustainable nutrition. These chemicals, excreted with their castings, comprise vermicompost, which improves soil texture, structure and aeration. From the Latin “vermi,” which means worm, vermicompost offers nutrients that are immediately available to plants. It can be applied as mulch, incorporated as a component in potting mixes or brewed in water as a compost tea liquid fertilizer.

Soil enrichment. University studies have shown vermicompost to actually add nutrients to the soil, which are immediately available for plants. This makes it superior to traditional "hot" composted material, and it makes it a nice organic alternative to chemical fertilizers. Purdue University reports that earthworms leave soil 5 to 11 percent richer in the essential plant nutrients of nitrogen, phosphorus and potassium than when they first ingest it. As an organic fertilizer, vermicompost is a substitute for synthetic fertilizer in soil-enriched vegetable transplant potting mixes. As a soil conditioner, vermicompost is superior to traditional compost for its ability to improve soil structure and increase its water-holding capacity, according to the University of California’s Project Compost.

It increases crop yields and plant growth. Gardeners and organic farmers like using non-synthetic amendments and fertilizers for the benefits it provides to the environment. But when these fertilizers also produce faster plant growth and higher crop yields, it’s an added bonus, says Clive Edwards of the Ohio State University Extension. Edwards’ collaborative field crop experiments on tomatoes, peppers and strawberries showed that plants fertilized with organic vermicompost significantly outperformed the same crops fertilized with inorganic, synthetic chemicals. Edwards’ research revealed vermicompost tea fertilizer yielded dramatic plant growth rates and crop yields of up to 50 percent.

I didn't know that a soil conditioner can make soil hold water better! My wife has starting gardening over covid, and with the drought happening where I live she has been having a hard time keeping her plants watered. I think I will send this article to her so she can read about soil enrichment and we can look more into soil conditioners.
