New agricultural air nitrogen fixing technology could result from Dr. Volkov’s plasma work
“Increasing the yield and productivity of crops is a priority for farmers and agricultural scientists,” says Dr. Alexandre Volkov, a professor of physical chemistry and biochemistry at Oakwood University since 1998 and a Future Technologies & enabling Plasma Processes (FTPP) lead investigator.
That’s why Dr. Volkov has been working to explore the effects of the highly energized forms of gas known as plasmas on plants.
“My friend Professor Vladimir Kolobov from The University of Alabama in Huntsville (UAH) often talked to me about plasma physics and interested me in setting up experiments with the plants Venus flytrap, mimosa and aloe vera eight years ago,” says Dr. Volkov, who was born in Moscow, Russia.
That work resulted in three published papers. Further publication came from research into the mechanisms of plasma interaction with plants and seeds, and experimentation with multielectron chemical reactions and plasma interaction with water, biologically active substances and biological tissues.
“The experimental and theoretical results of our studies of the interaction of plasma and biological objects will find wide application in medicine, agriculture and a new economical and highly efficient air nitrogen fixation technology,” he says.
In addition to the potential cost savings from the new technology, Dr. Volkov says direct application of plasma benefits plants.
“In the field, we discovered that plasma increases plant yields,” he says. “The average weight of a cabbage bean, whose seedlings were treated with plasma, was 70% greater.”
He says FTPP funding has been crucial to his research efforts.
“Without FTPP support, I wouldn’t be doing plasma.”
