Broccoli - California

Holden Research and Consulting tested the performance of a product containing SumaGrow® on broccoli production. This trial compared a product containing SumaGrow® in three different treatments: grower standard (100 percent fertilizer), grower standard with SumaGrow®, and a 20 percent reduction in grower standard with the addition of a SumaGrow® product. While the broccoli head weight was essentially the same for the first two treatments, when SumaGrow® was added to a reduced fertilizer treatment the yield increased by 9 percent.

Cucumbers - Bulgaria

This greenhouse trial was conducted in Yunatsite, Bulgaria on aG 23421 F1 hybrid cucumbers. The trial was conducted by Farmorganix, a licensee of BioSoil Enhancers, INC to determine the efficacy of using products containing SumaGrow® for field and greenhouse production. The trial data showed a 26% increase in yield for SumaGrow® treated cucumbers with accompanying increases in leaf mass and plant greenness which relates to more photosynthetic area for the plant. It was also noted that the SumaGrow® treated plants fruited an additional 14 days longer than the control.

SumaGrow treated lettuce compared with untreated lettuce
Lettuce - 8th Grade Science Experiment

"My 13 year-old granddaughter decided to do an experiment with SumaGrow® for her 8th grade Honors Science Class. She bought a packet of lettuce seeds dug some dirt out of her back yard and planted an equal number of seeds in each of two pots. One pot she treated with SumaGrow®, one was left on its own, except that she watered both with about 4oz of water every day or so. I visited with her over the Thanksgiving weekend (25 days later), and the attached photo is what I saw. I think she’s likely to win, don’t you?”

SumaGrow treated potatoes compared with untreated potatoes

Hi Wayne: What do you think of these potatoes? Richard Nellett brought these pictures to me yesterday and he was amazed. They leave their potatoes in the ground and dig them when they need them which looks like it was the end of November according to the date on the picture. He had no idea they were that big until he dug them up for dinner! His wife said that was the first time she only needed 2 potatoes for dinner.

I thought they were sweet potatoes, but he said that they are regular potatoes. They measure almost 8 inches long. The ones on the left, of course, were grown without SumaGroulx {SumaGrow® Inside}. He said it was no special seed potato, just what they had left over and he wasn’t all that careful about he applied the SumaGroulx {SumaGrow® Inside}, just poured it around the plant. I thought you might find this interesting.

Tomatoes - Barr Farms

Pam and James Barr picked over 1,000 lbs of tomatoes in one thankful, yet exhausting day. James and Pam have owned Barr Farms, a family dairy, for over 30 years and decided last year to grow their family garden into one for resale purposes.

Moving forward with their vision, they purchased a 30 by 96 foot high tunnel last fall with a cost-share from the Natural Resources Conservation Service that stipulated that all produce must be grown using organic methods. Pam chose to use only a product containing SumaGrow® . “We were introduced to SumaGrow® products about three years ago and loved the results,” Pam said. She expected good results, but was concerned what the extreme heat would do to this year’s crop.

“We’ve never had this kind of production before. It’s amazing the difference this product makes.” Pam found that out for herself as her friends and customers praised her tomatoes. “Everybody tells me these are the best tomatoes they’ve ever eaten.”

SumaGrow treated garden SumaGrow treated garden

Mr. Wayne Wade,

After seeing a news article on TV about your product, I decided to give it a try. I have a raised bed vegetable garden in the back yard of my home. I’ve gardened this way for the last several years. It has always been a successful way to garden, but I have never had such dramatic resutls as I have seen since using your Biosoil product only one time! The plants are greener, healthier, and stronger than they have ever been. They are larger, and each plant is loaded with fruit.

I was very skeptical about the product in the beginning, but I believe it will be a beneficial tool in gardening vegetables and flowers. All my plants have grown so green and so sturdy that I cannot wait to see the harvest. Bio Soil has made a believer out of me.

I have not used any commercial fertilizer at all and still have these great results using your completely organic product.

SumaGrow treated potatoes compared with untreated potatoes

Richard Nellet farms 700 acres of corn and navy beans in Munger, Michigan. “We treated half our crops with “SumaGrow®” and the results simply amazed us. We are seeing a 20% better yield on the SumaGrow® treated crops at a lower cost because the SumaGrow® costs less than the conventional fertilizer we have been using. Next year I am going to treat all my crops with SumaGrow®.

SumaGrow treated okra grows over 12 feet

The seed packet said okra can get to six feet. I just measured ours at 12’ 6” — and delicious!!!


A distributor for EarthCare Natural, SumaGrow® inside, reports in from Panama. The zucchini matured in 40 days instead of the normal 60ish days. Since they grow year round in Panama, this earlier maturation alone is equivalent to a 50% yield increase.

EarthCare also reports on a bok choy trial in California, applied and supervised by a third party, a major ag/chem distributor in the U.S. The crop matured in 36 days instead of the normal 45 days. Again, due to year round growing, this earlier maturation benefit is equivalent to a 25% yield increase. There was also an actual yield increase, fertilizer reduction and better taste.

Promised Land, using Genesis, SumaGrow® Inside, showed an increase in profit of over $70/acre, without adding in the fertilizer reduction on soybeans.

From Italy, the Agriculture Institute, Prever-Osasco, performed multiple replicates on five different potato varieties, whichaveraged a 13.4% yield increase using Solum Natural, a Grow Pros label.

Tall Harvest in Vietnam reports good results on dragon fruits, coffee (both old and producing trees), black pepper, and pearl onions. And from Cambodia, a longan tree (similar to lychee, not to be confused with Loganberry) plantation owner loved the early results.


Billie Davis, a farmer in Dover, Florida has been growing collards, mustard, scallions and black eye peas on his farm for 45 years.

"My young crop has never looked this good and healthy at this stage of the growing season,” Davis said shortly after using a SumaGrow®-containing product for the first time. “The bugs are not chewing on these young, tender plants.”

Mr. Davis used no fertilizer because of the recommended reduction or elimination of fertilizers when using a product containing SumaGrow®. “I have been spending around $2000 for my fertilizer. My SumaGrow® cost was under $500. I called and order my SumaGrow® and it was delivered within a week. A higher yield at a lower cost with fewer bugs is a win/win/win for my farm. I have already placed my SumaGrow® order for my spring crop.”


"I have a set of plants currently in their second week of flowering that have been receiving foliar application of your product once a week followed by a daily misting of reverse osmosis purified water until their due for their next feeding. I started them on this program as soon as they became well rooted clones.

I must tell you...I am absolutely amazed!

I have been growing the specific species of granddaddy purple for years on the exact same nutrient program and can say with confidence that that SumaGrow® has increased vegetative growth exponentially. I am continuing to use it through the flowering cycle and am excited to see what it does for the and resin production as well. I did not take pictures and will be sure to do so with this next group of plants. I have been sending a lot of my capitol to my mother and sister who have ran into some financial issues so I can not afford to run experiments right now, from experience with this species I will say SumaGrow® is 100% legitimate...Thanks for the magic...”

Talk to you soon Cody
