Sonic Bloom is a plant growth enhancer sprayed on crops as many as five times during early growth through blooming. A unique part of the treatment: You spray while plant metabolism is stimulated with an audible sound.

A battery-powered loudspeaker, modulated by a computer chip, warbles like a robin desperate for a mate in spring.

Lab studies show that nutrient movement within plants climbs as much as 700% under this sound frequency. It apparently helps the plant absorb and translocate nutrients and hormones in the spray.

A wide variety of farmer and lab tests with Sonic Bloom show 20% to 100% yield increases on fruit, vegetables, and field crops. The sound/spray process was developed in 15 years of research by Dan Carlson Scientific Enterprises of Blaine, Minnesota. Dan, a lone inventor, focuses most of his energy on research. He has not turned over his product to a major chemical company for marketing. Thus he hasn’t had the budget to buy standard land-grant plot tests typical of plant growth regulator development. He works mostly with farmers and a few scientists who aren’t afraid of concepts that literally sound a little weird.

Carlson says all of Sonic Bloom’s ingredients are "generally recognized as safe." He expects the product to qualify as an "organic" practice for certification with state organic marketing groups.


Three growers of sweet corn and other vegetables were equally pleased with their Sonic Bloom derived results. Don Jansen of Fort Meyers, Florida, grower of "Seaponic" vegetables, increased his cucumber count by 400%. In ten rows, each 100 feet long, his vines turned out 17,000 pounds, or 8-1/2 tons, of fruit so appealing he received 50 cents for each "cuke."

On the left bank of the Mississippi River not far from its source, Will Krahn, of River Falls, Wisconsin, tripled his sweet corn yield in his truck garden, attaining three ears on 65% of his cornstalks, and chalked up an estimated 50% plus increase across the board with such table vegetables as onions, tomatoes, peppers, baked beans, sweet peas, cucumbers, and even second-year asparagus. Some 225 miles to the east, Jim Percy of Sturgeon Bay also grew multiple-eared sweet corn; "Big Boy" tomatoes with clusters of 12 to 14 fruits instead of the normal 3 to 4; and the "best-tasting cucumbers I ever grew," for all of which he received premium prices at seven different small stores supplying "organic" produce.


Particularly impressive were tests of the sound and nutrient method run on soybeans by Gerald Carlson, a farmer and senior editor of Professional Farmers of America, in Cedar Falls, Iowa, whose long journalistic experience had made him highly skeptical of Carlson’s claims. In a formal report of his field trials, he stated that average yields were the following:


For untreated crops 37

For crops treated only with "Sonic Bloom" sound 44.2

For crops treated with "Sonic Bloom" sound and three

Sprayings of "Sonic Bloom" nutrients 51

For crops treated with "Sonic Bloom" extra sound and

five sprayings of "Sonic Bloom" nutrients 75.2

Gerald Carlson adds: "These trials were done in strips in three adjacent plots. Pioneer early beans were planted on May 20. The plots treated with sound only out-yielded the same variety on similar soils one-half mile distant and exposed to neither sound nor spray. Additional sprays on the five-spray acreage were applied by hand. Other sprays were applied by hand. Other sprays were applied by ground boom and tractor. Soybeans were visibly larger in treated fields, with an increase in pods per plant, pods numbering from 60 to 100. Clusters of pods were typically 5 to 7 per tract, sometimes as high as 9 per tract. The untreated beans had a tendency to behave like climbing plants, twining themselves both around one another and around the buttonweeds that grew up above the canopy. Treated beans had few nodules on their roots as compared to untreated which had normal nodulation. The extra sound was played continuously during daylight hours for two weeks in June."


At LaBelle, Florida, in the heart of one of Florida’s leading orange-growing centers, Roy McClurg, who will harvest in late March of this year, estimates at least a 30% increase in orange production on the 160 acres he treated. If last year’s prices hold, this will mean a $500 per acre increase in revenue. More significantly, his trees affected, like those of most Florida orangemen, with "young tree decline (YDT)," a so far incurable disease which shrivels their root systems, were beginning, under the Carlson-devised ministration, to return to health as shown by the fact that they were producing 50 to 60 oranges in contrast to untreated YDT trees that were bearing only 5 to 6. McClurg hopes that another year’s treatment of the recovering trees may bring them back to normal, which may imply a revolutionary solution to a disease problem on which the state of Florida has thus far fruitlessly spent millions of dollars of research money.

In mid-Florida’s community of Lake Wales, Rodney Dean, a nurseryman, treated Bitter, Hamlin, and Valencia baby orange trees to find that they quickly doubled in size as compared with untreated stock. The key to the doubling seemed to be the fact that the little trees receiving treatment put out leaves more than twice the size of the half-dollar sized leaves of their untreated neighbors, allowing them to reach a stage for transplanting in the field in two-thirds the time normally required.

In 1985, Carlson revealed the following inventory of information:

· Sonic bloom has now been tested on over 100 species of plants with marked success.

· Carlsonized huge white cauliflower heads could be packed only four to a box in boxes that normally contain a dozen heads . The Minnesotan farmer who grew the outsized heads which were disease-resistant and of exceptional taste, netted $200,000 on 20 acres, or $10,000 per acre. His costs for the treatment came to only $1,000.

· Soybean plants produced up to 300 pods per plant (30 to 35 pods is normal), with more beans on each side shoot than on any untreated plant. The beans, treated in Wisconsin, contained 27% protein as against a normal 15%.

· Cucumber vines with up to six (instead of just one) cucumber per leaf segment. "I call this challenging the seed," Carlson said.

· Papaya trees on the Big Island of Hawaii with 135 large papayas (normal 30-35). "See where they’ve been trimmed and cut back at the bottom . . . a lot of them usually die after that, but the sprayed trees began to put papayas out all over again," Carlson commented.

· On root systems between treated and untreated winter wheat plants, the treated ones were longer and lusher.

· Eight enormous lettuce heads filled to the brim a box that normally contains 24 heads.

· An old macadamia nut tree in Hawaii considered "past the age of production," was putting out nuts in all stages of maturity plus flowers, virtually becoming an "ever-bearing" tree.

· A greenhouse in Hawaii fed over 500 people with vegetables on just half an acre of growing surface . . . 20 large sacks per day of cucumbers were constantly harvested just 38 days after planting from seed . . . 70% increases over normal were recorded for squash growth and 50% for bush beans.

· An avocado tree in Hawaii produced fruit clusters of 18 to 20 avocados in place of the normal 1 or 2.

· A Florida orange tree was treated on one side only. The treated half revealed oranges in all stages of maturity, plus copius flower growth, making of it, like the above-mentioned macadamia nut, "ever-bearing." The untreated side was pedestrianly norrmal.

· Dill plants over four feet tall; calla lilies over six feet tall, bell pepper plants bearing 50 peppers and up, and African violets with 200 to 300 blooms (30 blooms being normal).

The implications of Carlson’s research and development are far-reaching, opening a horizon that promises to any person with even a small plot of ground the opportunity to feed himself, his family, and his neighbors at very low cost for plant nutrients applied. This, in turn, heralds an emancipation of countless growers from their enthrallment to the monopolies of agri-business and chemical companies.
