Worm Power, a world leader in organic vermicompost products, helps growers improve crop yield and plant performance through increased root development and plant nutrient uptake. Worm Power’s Vermicompost Liquid Extract is shelf-stable soil amendment from liquid worm castings that have hundreds of diverse bacteria species.
The company currently utilizes the microBIOMETER® test to evaluate field trials on how their product is impacting the soil when compared to an untreated control. They like having the ability to show growers that the product is functioning as intended for increasing microbes in the soil.
Many specialty crops sterilize the soil to avoid pathogens. The addition of Worm Power’s products strives to bring soil back to a healthy and functional microbiome. microBIOMETER® provides the grower a visual measurement of the microbial community over time and the improvements gained with each application of their product. Healthy soils promote healthy plants and having a diverse microbe population is critical to this process and the microBIOMETER® provides a great tool to support their efforts.
“microBIOMETER® lets us see immediate results rather than waiting to see the increase in yield at the end of the season.”
Bio-Extractor
Over the past decades, scientific awareness and appreciation of soil microbiology in agricultural systems has dramatically expanded. Flourishing microbial communities interacting with plant root networks play a direct role in plant growth, crop nutrition, disease and pest resistance, and soil aggregate structure, leading to increased soil oxygen flow and water holding capacity. Unfortunately, many agricultural soils have depleted functioning microbial ecosystems through decades of physical and chemical disturbance. Regenerating these microbial ecosystems is crucial to refocusing agricultural production on soil, human, and environmental health.
One extremely promising method of regenerating soil biology is through the production and application of liquid compost extract. Microbially-rich compost can be produced on-farm from locally-sourced and inexpensive organic materials, through systems such as the Johnson-Su bioreactor process and / or vermicomposting. Vermicompost also includes many naturally-produced bio-stimulants, such as humic and fulvic acids. These compost products, while valuable in solid form, can be extracted into a powerful liquid biological amendment to increase their efficiency and soil infiltration, inoculating beneficial microbes directly into root zones or onto the surfaces of leaves.
In addition to being both biologically beneficial and cost-effective to produce, liquid compost extract is also extremely versatile. Microbial foods, such as blackstrap molasses, kelp, and fish hydrolysate can be added for additional stimulation. Injecting oxygen into the liquid prior to application will activate the microbes and multiply the population (this is often referred to as “compost tea”). Application systems can be tailored to desired effects, including fertigation, soil drenches, soil injections, seed soaking, and foliar sprays. Improving soil biology not only benefits crop production, but also pastures, lawns, and turf, including athletic fields. Here’s a sample operation in New York’s Hudson Valley that uses compost extract for all of the above.
At Hiwassee Products, the goal is to help make this potentially transformative process both scalable and adaptable to a wide array of situations by designing and manufacturing innovative equipment solutions. The Bio-Extractor, released for production in 2022, is the only commercially available continuous-flow compost extractor to date, able to extract at 700 gallons per hour to meet any target volume, large or small. The company will continue to release equipment in the upcoming year, focusing on continuous-flow-through (CFT) vermicomposting systems and biologically-friendly spray systems, which differ from high-pressure chemical applicators. These equipment items can be combined into one closed-loop system (potentially including a pre-composting system to make vermicomposting more efficient), or be used as components of other soil biological management systems.
Lyons Worm Works
Ben Rodman is a vermicomposter with a love for all things biology and horticulture. His vermicomposting operation, Lyons Worm Works, has grown from simply diverting and reclaiming their household organic wastes into a small-scale but growing community effort.
Combined with all the spent substrate from their gourmet mushroom cultivation and gardening and brewing waste, Lyons Worm Works creates high-quality, microbially dense and diverse living vermicast for regional consumers. For Ben, providing quality vermicast to customers means having objective measurements of its quality for multiple reasons: integrity and trust, quality assurance, marketing, and constant experimentation to improve his product and process.
“Experimentation and real data has always been important to me; bridging my idealism with the real world we live in and grow our food and medicine in. microBIOMETER® is giving me fast, quantitative data to assess important considerations like feedstock quality, evaluating the impacts of process changes, durability and storage for finished product, and for fine-tuning my compost tea kit recipes so customers can make high-quality aerated teas at home. Having a fast, accurate and objective way to assess my products provides me with the data needed to make informed decisions. It gives my customers and I confidence that my products are going to help them meet their goals. What a great product for the small producer like me, for whom a home lab isn’t practical and routine commercial lab testing is prohibitively costly!”
Green Country Worms is a small worm farm located in Broken Arrow, Oklahoma. Their main focus is producing high quality worm castings. They started vermicomposting in 2008 when they received their first pound of compost worms. 12 years later they still love composting with worms and are fascinated with the worm castings they produce.
About a year ago they discovered their customers wanted proof of the quality of their product. While they could make claims about their worm castings, their customers wanted to see actual data. They periodically sent their castings to a certified lab to be tested, however, this is costly to do on a regular basis.
They love the microBIOMETER® soil test because it is affordable and it gives them a quick census of the microorganisms in their castings. They learned early on that a simple NPK soil test did not give them the data they were looking for. Being research minded they were also happy to find out that microBIOMETER® is involved in various university studies to demonstrate it’s validity and reliability as a soil testing instrument.
Green Country is currently using microBIOMETER® to compare worm castings that are produced with high quality malted barley. They feed malted barley in some of their worm bins and not in others.
Stay tuned! We will post the results of their experiment once it is complete.
