With the advice and assistance of the National Fertilizer Testing Center and the Dat Viet Xanh Farmers’ Association, in collaboration with Gia Lam District, fertilizer trials were performed with EarthCare with SumaGrow Inside broccoli at Yen Vien Commune, Gia Lam District, Hanoi.
The plant height increased, fewer pests were noticed, soil organic matter increased 67.5%, and, of course, the yield increased 37.5% while the chemical fertilizer was reduced by 50%, which resulted in a net increase in profit of over $431/hectare (May 8, 2018 exchange rate).
The use of EarthCare with SumaGrow inside reduced the urea nitrate residue in the broccoli. This is an important criteria for evaluating the product as safe or not before being used.
This trial was supervised by Dr. Ngo Thi Dao, Former Head, Department of Soils University of Pedagogy in Hanoi, who is also the author of two books on agriculture.
The report also contains detailed soil analysis reports.
The original report is in Vietnamese, which was translated into English: Vietnam Report in English — Broccoli
From the analysis carried out and the results obtained, it can be concluded that: The best production result was seen in the T2 [SumaGrow plus a 50% reduction in fertilizer], which shows a double saving. First, by increasing production by 51.5% and second by decreasing the use of chemical fertilizer by 50% • T3 (100% Genesis with SumaGrow) versus T1 (100% Chemical) shows an increase in production of 42.7% clearly showing the benefit of applying only (Genesis with SumaGrow) against traditional chemical fertilization.
T3 (100% Genesis with SumaGrow, no fertilizer) versus T1 (100% Chemical) shows an increase in production of 42.7% clearly showing the benefit of applying only (Genesis with SumaGrow) against traditional chemical fertilization.
There was an amazing increase in the soil health as measured by the Organic Material:

From the report’s conclusion: “Summa Grow (SumaGrow) at 1.0 gallons per acre did positively improve soybean performance (growth and yield) in low P2O5 and K2O soils despite having the recommended fertilizer rate reduced by 30%. This indicates that properly used, bio-stimulants can improve plant health and thereby improve yield. Even where no fertilizer was used, Summa Grow (SumaGrow) increased yield and performance of soybeans…”
This study is somewhat unique for a university study in that the study compared a product to both a Control and to a Grower Standard. We have long maintained that the typical study (touted by many of our competitors) compares a product to a Control of nothing but soil. This is NOT the real world.
Farmers want to know how a product will improve _their_ results in the real world. This means comparing what they are presently doing, referred to as Grower Standard, to whatever is recommended using a new product, in this case SumaGrow. While we believe the yield increase would have been higher than 13% if fertilizer had been reduced more than the 30% reduction used in this study, the 13% yield increase is a real world number which a farmer would have achieved since it compared what they are doing now to using SumaGrow with a reduction in fertilizer, which is recommended. SumaGrow with zero fertilizer even out-yielded the Grower Standard.
For the record, when comparing the SumaGrow results to the Control, again, used by most of our competitors, the yield increase was 20% according to this study.

SumaGrow does very well during heat waves and drought conditions. In this trial, the drought did not affect the yield on the SumaGrow plots, however, the control plot yield was very low. It was a fair trial, however, the yield increase was so great that we are going to mention. You will have to read the report your self to see the yield increase.
Notice how you can see the soil in the control plots while the SumaGrow plots are so dense, you cannot see the soil.

The report (link below) was written by a government agency with assistance from Nanjing Forestry University. The report did not specify an exact increase in yield, however, it stated, “all parameters related to plant growth vigor increased by more than 25% as compared with those of untreated tea trees” and SumaGrow “produces positive effect on the soil.”
The height, width, number of buds and size of buds all increased by at least 25%, leading us to conclude that the average yield increase was over 80% (see link to report below).
The tea leaves (right) appeared shiny after treatment with SumaGrow.

Bioprotectant with multifunctional microorganisms: A new dimension in plant protection
ABSTRACT In the present investigations it is proved that the inoculation of multifunctional microbial formulation to the soil improves soil quality, soil health, plant health, growth, yield, and quality of a broad spectrum of crops reducing chemical fertilizer and pesticide input. These microbial populations consist of selected species including plant growth promoting rhizo-bacteria, N2-fixing bacteria, Phosphate solubilizers, phytohormone producers, plant disease suppressive bacteria and fungi. To make it very simple a different dimension as „Bio Protectant” is given in this presentation to the collective synergistic effects of beneficial microbes stimulating soil, plant and environmental health reducing chemical fertilizer and pesticide application. A healthy plant does not require unwanted, poisonous chemical pesticides. Review of literature is focused in multiple ways on the growth promoting ability along with the biological activity of beneficial microorganisms. The present SumaGrow-F2 formulation contains multi-functional Rhizobium species, Pseudomonas spp., Bacillus, and Trichoderma spp. The recorded novel benefits of SumaGrow-F2 formulation in the Green House and Field are discussed here as microbes increasing plant health, soil health, and root health of a broad spectrum of crops. Not only can it eliminate almost all insect infestations and reduce fungal or bacterial infection, it also creates a healthier environment for plant growth. The result is healthy crops with a corresponding increase in the yield of fruits or vegetables or grains. Modern trend is to look for inspiring intelligent multi-functional microbial Plant protectant or bio protectant for sustainable agriculture.

The following pictures were taken at Breckenridge Farms in Quitman, Mississippi. You can see a noticeable difference in the development of the vines. Where SumaGrow was used the vines of adjoining plants are full and meeting in the middle on the trellis. The untreated vines lack fullness and are not even close to meeting in the middle.
Last summer the treated vines produced over 4 tons per acre and untreated was only close to one ton per acre!
These grapes are juiced at a winery in North Carolina. In the southeast U.S., they are mainly eaten fresh and used to make jelly and home-made wine.
“The effect of SumaGrow on young varieties of muscadines has been proven to be significantly noticeable. After using once on half of a selected field of young plants we had a increase in growth of up to 50% per plant. SumaGrow has become part of our program to grow young plants faster. It not only enhances growth but also seems to improve the overall health of the plants.”
