Initially the goal was to keep the wriggling worms alive, to use a jolt of electricity to stimulate their nerve cells in the pursuit of scientific discovery. But the research device was malfunctioning and killing the nematodes outright.  Electrical engineer and entrepreneur Jason Crisp fixed the machine, nipping some stray voltage that was causing electrocutions. The worms lived. Done and done.  Except it wasn’t.  Crisp began wondering about useful applications of that electricity to target soil nematodes that can damage valuable crops and vegetation.  That spurred the idea for what is now Lisi Global, a Richland, Wash., startup that replaces chemical pesticides with devices that zap soil pests with a jolt akin to a controlled lightning strike.

Republished from Organic Grower:

Lisi Global Inc. is taking part in the latest US Department of Agriculture/National Institute of Food and Agriculture grant focused on methyl bromide replacement.
Lisi Global’s Directed Energy technology explores alternative approaches to soil fumigation using electric pulses applied to the soil to control target organisms. Photo: FileIn partnership with researchers from Oregon State University and the USDA Agricultural Research Service at OSU, Lisi Global will adapt its Directed Energy technology to explore alternative approaches to soil fumigation using electric pulses applied to the soil to control target organisms, as well as continuous electrical current to heat the soil as a means of disinfection. The two-year study also includes economic analysis to determine how cost-effective these pest management tools will be.
According to OSU professor Dr. Marcelo Moretti, the grant’s Principal Investigator, “Lisi Global’s technology demonstrated efficacy in early greenhouse trials, and the impressive results produced in the early stages of their turf pest control efforts make it worthy of evaluating on a larger scale. We are grateful to the USDA/NIFA for the opportunity to look closely at DE Technology as an alternative to fumigation.”

Managing Earthworm Casts on Golf Courses

USGA Green Section article mention of Lisi Global's pulse power technology!

"When the average person pictures a healthy soil in their mind, they probably have an image of a loose, dark-colored soil that is somewhat moist and filled with earthworms. Just Google “healthy soil” and you’ll be presented with countless photos of people holding that exact thing. Many people associate earthworms with soil health, and for good reason. Earthworms are beneficial for soil aeration, water infiltration, thatch control, nutrient recycling and they can increase microbial activity. They are truly movers and shakers when it comes to soils. 
There are over 7,000 different species of earthworms which are divided into more than 700 genera and 23 families (Edwards, 2021). Only a small fraction of that total is native to North America. Most of the earthworms that dominate our soils here in the U.S. were introduced from Europe and Asia. Lumbricus rubellus, the red earthworm, is a familiar sight in many American gardens, but it’s actually an earthworm from Europe that was most likely introduced via soil from early settlers."
