South Africa Lucerne (Alfalfa) Achieves 130% Yield Increase

Lusern-Alfalfa-South Africa -- field comparison160126

Mr. Francois van Rooyen, a lucerne and pecan nut agriculturist, carried out the following interesting controlled test on his lucerne.

  • The right-hand field was treated with ExploGrow™ (SumaGrow).
  • The left-hand field was not treated.
  • The soil is the same in both fields: very brackish and shallow water table, and is well drained with underground pipes.
  • In all other respects the two fields were treated the same, except a variation in the type of Lucerne.
    On the left hand field: Sardi 10 cultivar. On the right hand field WL 711.
  • Both fields were therefore top producers with low dormancy and both fields were also treated identically with organic acids, clay minerals, macro-elements, micro-elements and activated carbon, to provide an effective and balanced soil due to brackish conditions prevailing in the area.

ExploGrow™ (SumaGrow) has just raised the maximum yield ceiling for my land and a 130% increase in yield represents a massive increase in profits.”

UPDATE: Results after harvesting Lucerne

  • Harvesting took place during March/April 2016
  • Yield increase: 130%
  • The ExploGrow™ (SumaGrow) treated area produced 23 tons per hectare versus 10 tons per hectare from the untreated area.
  • Better plant health on the ExploGrow™ (SumaGrow) treated area showing a “remarkable difference compared to the untreated area”.
  • After a severe and damaging drought, I would attribute the radically superior yields on the treated land to the bigger root systems, reduction in watering requirements and improved plant health, delivering over 23 tons per hectare compared with only 10 tons per hectare for untreated area.” Mr. van Rooyen

Lucerne-Alfalfa -- South Africa close up

Based on his expertise in balancing soil, Mr van Rooyen offers his analysis as follows:

I believe that the carbon and organic acids act as excellent food for the ExploGrow™ (SumaGrow) microbes.

In nature, manure (for example) releases organic acids and then feeds organisms from the animal’s intestines that generates diverse populations of ground microbes. Without the dung, the microbial populations would not develop, because some form of energy needs to drive the microbial activity. It is not enough to only use a balanced vitamin and mineral supplement. You also need protein, carbohydrates and other energy-rich compounds to function at the optimal level.

I therefore believe that the organic acids in my fields provide the energy to the microbes to develop a diverse strong population. This diverse population can now execute various tasks like (a) extracting minerals from the soil solution and (b) helping the plant to absorb the minerals. 

Microbial activity fuels a high rate of multiplication. This impacts positively on the plants also acting as a precursor to the plant’s own productions of hormones, resulting in stronger growth, like I observed with ExploGrow™ (SumaGrow).

The ExploGrow™ (SumaGrow) microbes develop a diverse population in symbiosis with the plant. This diverse group of microbes carry out several critical functions such as binding of atmospheric nitrogen, releasing phosphates etc. In this specific case of brackish soil, the microbes make the excess iron available to the plant for consumption, which would otherwise be detrimental to root establishment and growth.

I believe this is clear from the photo, when looking at the left-hand field. One can clearly see in the photo that on the untreated left field the plant microbial interaction is poor, although this field has an otherwise absolutely balanced fertilization program.

The soil in the left field is simply poor in essential microbes.

Looking at the right-hand field treated with ExploGrow™ (SumaGrow), the picture speaks for itself!

On my farm I noticed an extraordinary difference in the presence of lice (“Bladspringers”). The ExploGrow™ (SumaGrow) treated areas were virtually unaffected compared with the untreated areas that were severely affected. Furthermore, three other farmers that I supplied with ExploGrow™ (SumaGrow) experienced similar results.

At the end of the season Mr van Rooyen shared the following observations:

  • A very intense drought hit the central and western regions in South Africa. 
  • Insects such as Bladspringer (Leafhopper) that normally survive in the field, fed on Lucerne for the whole summer, causing severe damage.
  • The ExploGrow™ (SumaGrow) treated area had a very positive effect on the resistance of the plants against insects.
  • Where farmers applied ExploGrow (SumaGrow) in the spring, there was visible resistance. The population of the insects were much smaller on the ExploGrow (SumaGrow) treated areas. Also, there were far less marks on the leaves in the ExploGrow (SumaGrow) treated areas.
  • Within six days of the end of March we had 150 mm of rain. 
  • The treated Lucerne survived much better in the wet conditions than the untreated Lucerne.
  • In the end, production varied from 10 tons for the untreated Lucerne and 23 tons for the treated Lucerne.”
 “ExploGrow™ (SumaGrow) is a winner!

Pecan Nuts

“I made the same observation on Pecan Nut trees, in an orchard where 40% of the trees were dying – although the soil was perfectly balanced with organic acids elements etc.  After treatment with ExploGrow™ (SumaGrow) there was a total recovery.”

South Africa Potato Trial Increases Yield 79% and Brix Levels by 57%

In South Africa, and some nearby African countries, SumaGrow is marketed under the ExploGrow name.  Here is a video of a potato trial, which increased the yield by 79% and the brix (natural sugars and nutrients) levels by 57%!

Soil Health Shows Significant Improvement; A Sports Field Study in Costa Mesa, California

There are numerous benefits to using AgriBiotic Microbics with SumaGrow.  While most of our success stories focus on increasing yield and reducing or eliminating fertilizer, the before and after soil analyses (see link below) demonstrated significant improvements in the soil’s water efficiency and the nutrients measured in the soil increased from 8% to 91%.
 Costa Mesa BeforeCosta Mesa After

The soil samples are from the Jack R. Hammett Sports Complex, owned by the city of  Costa Mesa, California and were treated with AgriBiotic Microbics with SumaGrow.  Since the sports fields use recycled water, it makes high pH and chlorides a constant concern.  Despite these added issues, in less than three months, the pH in the treated fields went down slightly and the chloride and salinity levels dropped 26% and 34%, while the soil moisture (field capacity) increased from 63% to 69%.

Costa Mesa Salinity Chart

Soil salinity is the salt content in the soil.  Salt affected soils are caused by excess accumulation of salts from high salinity irrigation water.  As soil salinity increases, salt effects can result in degradation of soils and vegetation.  Accumulation of soluble salts (brine, salt and chloride may be used interchangeably for our purposes) is not normally a hazard to human health; however, it can cause adverse and long lasting environmental impacts to soil and ground water resources because chloride is highly soluble, does not adsorb onto soil particles, does not degrade, and generally inhibits biological processes.

Releases of salt onto the ground can damage soils by destroying the soil structure and permeability.  The presence of high concentrations of soluble salts can inhibit see germination and a plant’s ability to uptake water. Salt-contaminated soil in the near surface can lose its ability to support agricultural crops, native grasses, or other vegetation if salt levels are high enough, potentially contributing to surface erosion.

Chloride is the most recent addition to the list of essential elements and is essential for  many plant functions; however, too much chloride in plants results in symptoms that are similar to typical cases of salt damage. As shown in the attached reports from the city of Costa Mesa, the chloride target is <150 and AgriBiotic Microbics with SumaGrow brought the chloride from an average of 210, outside the target range, down to an average of 137, well within the target range.

Soil Moisture (or Field Capacity) is typically defined as the quantity of water or moisture contained in the soil 2–3 days after rain or irrigation.  AgriBiotic Microbics with SumaGrow increased the ability of these fields to hold water.

Sodium Adsorption Ratio (SAR) is a measure of the suitability of water for use in agricultural irrigation as determined by the concentrations of solids dissolved in the water.  Although SAR is only one factor in determining the suitability of water for irrigation, in general the higher the sodium adsorption ratio, the less suitable the water is for irrigation.  Irrigation using water with a high sodium adsorption ratio may require soil amendments to prevent long-term damage to the soil.  If irrigation water with a high SAR is applied to a soil for years, the sodium in the water can displace the calcium and magnesium in the soil.  This will cause a decrease in the ability of the soil to form stable aggregates and a loss of soil structure and tilth.  This will also lead to a decrease in infiltration and permeability of the soil to water leading to problems with crop production.

These laboratory reports clearly show the soil’s water efficiency being improved. There is more water in the soil as evidence by the higher soil moisture percentage, the water in the soil is more available to the plant life since the lower amount of salts in the soil allow more soil moisture to be used by the grass being grown and the SAR indicates the water in the soil is a higher quality water than before treatment started. The results were achieved without any significant rainfall.

Costa Mesa Nutrient Chart

The nutrient levels increased across the board with every element measured showing increases, some very significant.  This is especially significant when considering the short period of time between the soil tests and accepting that AgriBiotic Microbics with SumaGrow is primarily a microbial product which takes more time than fertilizer to show initial results.

The city of Costa Mesa, did continue its fertilization program (slow release 32-0-0) during the field trial, however, this would only have affected the increase in soil available nutrients for nitrates and even then, not to the degree shown. Further, other field trials using AgriBiotic Microbics with SumaGrow show even better results if fertilizer is reduced by at least 50% or eliminated altogether.

The microbial formulation of AgriBiotic Microbics with SumaGrow would have to be given the credit for the 48% to 91% increases in manganese, zinc, copper, boron and magnesium, all essential nutrients for optimal growth.

Independent Soil Analysis:



Texas Winter Wheat Trial Increased Net Profit 44.9%

This comparison test was conducted on 500 acres of Fannin Ranch, north of Dallas, Texas.  The field was divided in two, 250 acre sections, and planted with Red Winter
Wheat.  On one section, AgriBiotic Microbics with SumaGrow was applied shortly after planting in a single application.  The other section was treated with two applications of Ammonium Nitrate fertilizer.  The photos below were taken just before harvest in May.

There is an obvious visual difference in the height and density of the two wheat fields. The grower reports that wheat heads on the SumaGrow wheat were significantly larger and yielded 36-40 seeds per head, compared to 30-34 seeds per head in the fertilized wheat.  Texas Wheat Trial Agribiotics Wheat Tillers

The results were overwhelmingly in favor of the AgriBiotic Microbic Products w/ SumaGrow.  Not only were input costs lower in treating the soil, but that section outperformed the other section by netting an average of 14 additional bushels per acre for a net profit increase of 44.9% per acre.
