Yield Increase Results

Though we are mainly a soil amendment which may aid in the increase in microbial development here is what has been reported by farmers, Universities and third party testing facilities about our Sumagreen products all over the world.

2016 Honduras
Seeing less disease in coffee plants by decreasing the Roya (basically like rust in the USA) while having very good yield results which vary from farm to farm but in the ballpark of 18% increase in coffee beans.  Farmers in Honduras are more excited that they are noticing less Roya disease in plants by using the SumaGreen then they are with any yield increase.  Which only goes to show you that if you take care of your soil only good things will happen.

2015 Vietnam
Increase in production of Chrysanthemums (flowers) while increasing the shelf life by 7 days longer then the fertilized flowers.    We are now working with the coop of rice growers and initial results look very promising but will not have final numbers until 2016 

2014  Farm Day Trials  -  MONTANA
Held in Glendive, Montana results shown from their own John Deere Combine computer print out of the yield increases.  An Organic Wheat farm showing an increase in yield of 38.75% Increase in yield, netting him a extra profit of $111.60.  While a tradition farmer saw increases on POOR fields of 58% and on GOOD fields he saw a 13.5% yield increase.   See more on the results.

Arise Summary paper on results

The validation testing at the Arise Research facility was performed primarily to determine the effect of a product containing SumaGrow on the amount of tile water runoff and the percentage of nitrates contained in the runoff water.
     There are five test plots covered by this report: one control plot using the state recommended amount of conventional, petrochemical based fertilizer for corn grown in the State of Illinois; two plots treated with a product containing SumaGrow and 100% fertilizer; and two plots treated with only 50% fertilizer and a product containing SumaGrow.
      Throughout the report, treatment #1 are the two plots (or their average) treated with 50% fertilizer and a product containing SumaGrow (SG50). Treatment #2 is the two plots (or their average) treated with 100% fertilizer and a product containing SumaGrow (SG100). Treatment #3 is a single control plot consisting of 100% fertilizer only (100)

The Significant findings are as follows:

                                                   100         SG 100      % Decrease          SG50         % Decrease
Runoff water 7/20 – Gallons     77.0        40.0            48.05%               36.5             52.60%
Runoff water 9/30 – Gallons     37.0        19.5            47.30%               16.0             56.76%
Nitrates in Runoff 7/20             24.0         12.5            47.92%               15.5             35.42%
Nitrates in Runoff 9/30             16.0         13.0            18.75%               11.5             28.13%

The runoff water and nitrate data are from page 9 of 17 of the Arise Research report. The runoff water is identified as “Well Water” – runoff water from the containment bays is collected in wells. The nitrates in the runoff are identified in the report as “Water Nitrates.” Both SG50 and SG100 decreased the amount of runoff water significantly with SG50 reducing runoff water by an average of 54.68% and SG100 reducing runoff water by an average of 47.68%.
       Perhaps more importantly, the nitrates in the runoff water were significantly reduced as well with SG50 reducing nitrates by an average of 31.78% (which had 50% less nitrogen placed on the soil to begin with) and SG100 reducing nitrates by 33.34% compared to the conventionally fertilized control plot. Please note the nitrates are measured in Parts Per Million (PPM), therefore, the reduction in runoff water, and a reduced percentage of nitrates in the
Nitrate Runoff Reduction Summary Version 1.1 1/27/12
runoff water, combine to reduce the total nitrates by 69.08% for SG50 [1-((1-.5468)*(1-.3178))] and 65.12% for SG100.
       It is imperative to realize this remarkable reduction in nitrate runoff was achieved without cost! In fact, there are additional benefits to farmers, the consumers, and the environment as the chart below highlights some additional data excerpted from the Arise Research report.

100             SG100       % Increase       SG50        % Increase           
Yield                               119.3         145.15             21.67%         142.20            19.20%
Chlorophyll (9/30)          40.2             54.0              34.33%           53.15             32.21%
Formazan                       314.0           406.5             29.46%           444.5             41.56%

The yield on the corn crop increased by 21.67% for SG100 and by 19.2% for SG50 compared to the control. Again, please remember the control is what a typical farmer is currently doing. These yield increases are worth over $160 per acre (page 6) and the manufacturer of SumaGrow products recommends at least a 50% reduction in fertilizer which would easily have increased the financial benefit to the farmer by at least another $40 bringing the total financial benefit to over $200 per acre for the farmer using SG50, which far exceeds the cost of products containing SumaGrow.
       This yield increase is not a fluke as it has been repeatedly demonstrated in numerous field trials and with actual large scale farmers. There is additional data in the Arise report which further lends credibility to the increase yield claim: The plots treated with a product containing SumaGrow had better plant health, wider leaf diameters, bigger stalks and better color.
Consumers of corn grown with products containing SumaGrow benefit since a free market will lower the purchase price for corn as more farmers adopt the use of products containing SumaGrow.
       Additionally, chlorophyll is a good proxy for overall plant nutrient value. The corn used is this field trial was field corn which will likely be fed to cattle. Better nutrient values will lead to increased/faster weight gain for cattle eating this corn – another benefit to the consumer of this crop.

Field corn may also be used to make ethanol. While this study did not measure the brix of the corn kernels (just the plant brix), other field trials have demonstrated products containing SumaGrow significantly increase brix levels. Higher brix levels lead to more ethanol per bushel of corn.
       The environment is also a winner. In addition to the nitrate runoff reduction highlighted above, fewer gallons of water running off reduce the loss of topsoil and resulting clogging of waterways which would ultimately need to be dredged.

Nitrate Runoff Reduction Summary Version 1.1 1/27/12
      For the soil which does not runoff, the quality has been improved as demonstrated by the Formazan results. The Formazan test provides the biology in a soil sample with a specific amount of a food supply and waits a specific amount of time. The amounts of metabolic enzymes given off by the bacterial and fungal species are measured when they are active. The Formazan test is like the speedometer reading of microbial activity in the soil. It is an indirect microbial assay that gives us a picture of the forest—not the individual trees.
        Low Formazan readings indicate a poor cycling of carbon, less microbial activity, and the inability of soil to break down organic inputs to supply plants with available nitrogen. The higher the Formazan reading the better and the product containing SumaGrow increased the Formazan levels by 29 to 41%.
        The manufacturer of products containing SumaGrow believes the cost/benefit ratio to the farmer is significant enough to allow widespread implementation via the “carrot” approach – where every party benefits – rather than finding an alternative solution utilizing the “stick” approach which will have extra costs for the parties involved

COTTON - Tarboro, North Carolina

Summary of results
Bar graphs of results

These results show the yield and quality increase on a 138 acre cotton farm in Tarboro, NC. The cotton farmer also raises chickens so approximately 13 tons of chicken litter was applied. A product containing SumaGrow was used on 65 acres with no additional fertilizer while the remaining 73 acres was treated with chicken liter, as well as 40 units of nitrogen and 25 units of sulfur fertilizer per acre.

Treated Cotton -- 69,582 pounds divided by 65 acres =  1070.49  lbs/acre   16.92% Increase
Control Cotton  -- 66,837 pounds divided by 73 acres =    915.58  lbs/acre

                       Total Dollars per acre

Treated         1070.49  pds x  0.92$   price/lb =   $989.55
Control           915.58  pds x  0.52$  price/lb =   $480.20

Treated  $989.55    vs.    Control  $480.20   =   106%    Increase in Revenue

Combining the higher yield with the higher quality price received, the farmer increased his revenues by 106% per acre ($989.55 vs. $480.20). Actual bottom line profits would be an even greater percentage increase as all other expenses stayed the same, with the exception of the fertilizer expense, which was actually lower on the treated acres since no commercial fertilizer was used.
The farmer had previously told our distributor he would use a product containing SumaGrow next year on all of his soybeans, however, after seeing the results on his cotton; the farmer has now decided to not plant any soybeans, just cotton!

Rice in Beaumont, Texas
Although organic rice production is often seen to decline after multiple harvests, the above rice farmer saw a yield increase of 23.44%. Click here for Rice Results from Beaumont.

Football Field in  Salem, Illinois

The treatment began by killing off the existing grass. Then 100 pounds of seed rather than the normal 120 pounds was power seeded into the field. The field received one treatment (at 1/2 the normal application rate) of weed control. The typical second application of weed control was cancelled as the grass was so thick, there were no weeds.

There was a 95% grow in, the normal measurement of a fully grown field,
was achieved in 8 weeks rather than the typical 16-18 weeks.

Bottom Line:
100% reduction in fertilizer, 16.7% less seed, and
75% less weed control products, and in half the time!

Murray State University

The above chart illustrates a field trial conducted at Murray State University in Kentucky.  BMR Sorghum was tested using different fertilization treatments including SumaGrow only, NH4NO3, raw milk and control (no treatment). Sorghum treated with SumaGrow containing  products yielded higher Brix (nutrient density) than every other crop treatment.

Crops with higher Brix are sweeter tasting and more aromatic. Sweet tasting grasses speed the growth of cattle and sheep and lower greenhouse gases.

Taylor Farms, Louisiana

In this chart is an illustration of trial results from Taylor Farms.  Three treatment methods were applied:

SumaGrow- 1 gallon split application

SumaGrow + Fertilizer- 1 gallon split application + 275 lbs/acre 3-2-1

Control- 275 lbs/acre 3-2-1

The results from Taylor Farms were indicative of the results from most forage and hay crops tested during the 2011 field trials. SumaGrow-only treated grasses had higher yields and increased nutrient density than grasses treated with conventional fertilizer programs.

Tallgrass Beef Company - Brix and Yield

In a study conducted by Tallgrass Beef Company and overseen by Dr. Allen Williams, not only did plants treated with SumaGrow products have higher yields, but they also had higher Brix readings over a 10-week period than those treated either with Liquid Broiler Litter or Urea.  Following is the yield chart based on results reported to us from Tallgrass.

According to Dr. Williams, a prominent figure in the grass-fed beef industry, the definition of Brix is,  “The measurement in the amount of plant solids versus the water in the plant. Those plant solids [are] sugars, amino acids, vitamins, minerals, some fats, and plant sterols. When you’re measuring that, you’re measuring the true nutrient density in that forage by taking a Brix measurement.” In other words, high Brix readings usually indicate healthier, tastier plants that animals prefer. The following two graphs show the Brix results of SumaGrow versus urea and liquid broiler litter as reported from Tallgrass.

Phosphorus Results

A phosphorous removal test was conducted on soil when levels exceeded the allowable limits for using chicken litter as fertilizer. A soil sample was dried, and part of it was treated with SumaGrow. Afterwards, the treated soil was filtered and dried, and the untreated dry sample (control), the treated dry sample, and the filtered liquid (supernatant) were sent for phosphorous testing. 

After averaging the 11.5 for the dry soil and the 3.8 of the extracted liquid, the phosphorous analysis totaled 7.65.  Subtracting this from the control (33.5) means that 25.85, or 77.16%, of the phosphorus has now been converted to phosphate and is available for plant uptake.

SumaGrow treated fields thrive despite early frosts,
untreated fields are destroyed


 (Left) SumaGrow treated tobacco field; (Right) Tobacco field treated with fertilizer only. Note the missing plants in the rows and the size of the leaves.  

SumaGrow treated tobacco fields  in Virgina, North Carolina thrived despite five early frosts while the untreated fields were completely destroyed.

Thomas Elliott, owner of Elliott Farms, grows around 100 acres of tobacco among other crops.  Elliott treated 30 acres of tobacco with SumaGrow at the recommended split application of one gallon per acre. Both treatments were foliarly applied (leaf as opposed to soil application).  The remaining acres were treated only with conventional fertilizer.The SumaGrow treated fields had no disease or pest problems, not even  the dreaded tobacco worm, despite having received no pesticide or herbicide application.  The leaves were golden all the way to the top and perfect for harvesting. The untreated fields were destroyed by the frost and are not harvestable.



SumaGrow treated tobacco plant.  The leaves on the top of the stalk are  36+ inches long with no frost damage.

Frost damage occurs when the water inside the plant freezes and forms ice crystals, puncturing the plant cell walls. Because SumaGrow treated plants are more nutrient dense, they contain less water and are less likely to be damaged by freezing temperatures.

SumaGrow is an organically based consortium of non-genetically modified microbes that improves the health of the soil, increases crop yields and reduces expensive input costs. Because SumaGrow treated crops are stronger and healthier, they are better able to resist extreme temperatures,  high winds and drought. SumaGrow increases soil organic matter and helps to balance the soil pH, creating a vibrant microbial environment attractive to beneficial organisms and bugs.
