The trial compared a grower standard grape production protocol to the standard plus additional applications of Nualgi Foliar Spray. The section that received Nualgi Foliar Spray showed visible increases in berry size, cluster fullness, and accelerated fruit coloring. It yielded 14.99% more boxes of grapes and $2,470 more in profit compared to the grower standard section. The addition of Nualgi Foliar Spray improved plant growth, stress tolerance, and productivity.

3. 1. Introduction
Nualgi America, Inc. has engaged JTP Agriculture and Irrigation Consultants to conduct
field trials of its foliar fertilizer product, Nualgi Foliar Spray. NualgiAmerica also markets
water treatment products such as NualgiPonds and Nualgi Aquarium. Nualgi America is
based in San Marcos, CA.
Nualgi Foliar Spray is an advanced nano scale foliar spray, which combines a balanced
mix of 13 plant nutrients in a single formulation. It contains primary nutrients (P,K);
secondary nutrients (Ca, Mg, S); Micro Nutrients (Fe, MN, Zn, Cu, B, Mo) and in addition
Silica and Cobalt. The particle size is between 1 and 30 nano meters. It is unlikeother
foliar agents, which comprise of limited nutrients in the formulation. All nutrients are at
nano scale allowing for easier fluming in the tank and smaller micro droplets during
application.
This report covers detailed data and commentary on the trial of Nualgi Foliar Spray
applied to a processing tomatoes crop in Firebaugh, CA from planting to harvest during
May-August 2015
2. Objective
The objective of the trial is to prove or disprove the efficacy of Nualgi Foliar Spray on
fresh market grapes based on grower standard with a minimal approach of including
Nualgi Foliar.
3. Methodology
3.1 Trial Location
Trial was performed in Kingsburg, CA on a 2.5 acres section located in 60-acre
block. Kingsburg was chosen, as it is an ideal location within the fresh market
grape production area of California.
3.2 Weather, timing
The climate of the Kingsburg area is relatively cool and moist in the winter and
warm and dry in the summer. Relative humidity readings of 15 percent are common
on summer afternoons, and readings as low as 8 percent have been recorded. In
contrast to this, humidity readings average 90 percent during the morning hoursof
December and January. Average monthly temperatures range from 45.3°F in
January to 80.6°F in July. Summer weather is typically at or above 90°F over100
days per year. Temperatures of 32°F and below occur only about 27 days per year.
4. Central California’s weather is mainly influenced by the North Pacific High Pressure
system. During the summer, a high-pressure ridge develops over the Pacific Ocean
blocking the penetration of moist air from the Pacific. This high-pressure system
tends to weaken during the winter months thereby opening the door to Pacific
storms. Nearly 90 percent of Firebaugh’s annual precipitation falls in the six months
between November and April. The mean annual rainfall is 8.27 inches.
Air movement through the San Joaquin Valley is usually in a northwest to southeast
direction. Wind enters the Valley over the passes east of the San Francisco Bay and
exits through mountain passes at the southern end of the San Joaquin Valley,
principally Tehachapi.

5. 3.4 Irrigation
Irrigation for grapevines are done based on a simplistic approach and usually
focuses on crop appearance and feel. Some growers enlist pressure bomb
readings and irrigate based on the negative bars reaching 11 to 13 bars, which
means that it’s a limited stress irrigation. This is a little different for fresh
market grapes and the crop loads are heavier and therefor need a good amount
of water to keep them moving. Drip irrigation using above ground lines with ½
gal per hour emitters are utilized and irrigation is done at 6 gal per plant per
week through the growing season. Water is slowed during harvest to allow
ripening and avoid swelling with water and lowering sugars (brix). After harvest
is completed a 24-hour set is put down to start storage in the plant for the
coming season.
3.5 Test Protocol
This trial consisted of 2 trial segments focusing on the grower standard, as well
as grower standard with the addition of Nualgi Foliar.
Grower Standard: Growers standard consisted of multiple injections and foliar
throughout growing season. At swell an application of 3-18-18 was applied at
10 gal per acre. Twelve inches of growth a foliar application of evergreen was
applied at 1qt per acre and an injection of Calcium Thiosulfate at 15 gal per acre
followed by 1 gal of AgroBactor. At twenty inches of growth and pre-bloom a
foliar of Zinquexx at 1 qt per acre plus Magnet B at 1 pt per acre with 1 gal of
AgroBactor per acre and Fosfi-Cal at 2 pounds per acre drip applied. Post bloom
application of potassium thiosulfate at 20 gal per acre was used with a foliar of
Best K at 1 qt per acre. Swelling an additional application of AgroBactor was
applied with Best K and Saeta Gold each at 1 qt per acre.
Grower Standard + Nualgi Foliar: The only difference between this plotand
grower standard was the application of 6 foliar shots at 200ml per application of
Nualgi Foliar.
6. 4 Trial Milestones
4.1 Growth and Output
There was a visible growth difference between the section that was applied with
NF as an add on. We saw a visible increase in size of berries, color of leaves and
overall fullness of clusters.

4.2 Nutrient Assessment
There were no noticeable differences between the grower standard and the
reduced grower standard with the addition of Nualgi. One element not analyzed
in current lab protocol is Si. This will need to be observed in the future asthe
overall growth and impact of the plants respiration is driven by Si, a key partof
Nualgi.
4.3 Color
Visually you can see a size comparison of the crimson seedless based on the use
of a quarter as well as the cluster in the center was treated with NF versus
Grower standard. This became fully colored 11 days sooner as you can seethe
2 GS clusters in various stages ofripening.
8. 4.4 Plant Stress Assessment
One thing that we needed to consider is the overall impact of waterand
environmental stress points and how that affects the plants ability to
continue respiration. When plants come under any stress whether
environmental due to mainly heat or dehydration due to water deficit
irrigations the plant slows and therefore affects yields and quality. Wedid
not consider the quality of the water as a factor but this should be
considered in the future as wells get lower and heavy metals increase. We
would also look at Na issues in the water and the effects on plant growth
and performance when utilizing Nualgi in the future. The look of thecrop
before harvest is a perfect sign of overall stress impact and how the addition
of Nualgi helped.
10. 4.5 Pest and Disease Resistance
While the use of Si has been proven to decrease diseases and orpest
pressures we didn’t perform these test, as Nualgi will be utilized asa
nutritional and not as a dual-purpose material. We did visually see novisible
issues in the NF blocks but no relationship was established.
5. Return on investment
We calculated the ROI based on boxes picked and the additional cost per
box versus profit.

11. If you take in consideration of the increase in cost of application of the NF at $200 per acre the
overall impact to the yield and profit improvement was $2470.00. There is no other ROI
consideration needed as the only variation between plots were the additional applications of
NF.
6. Trial Comments
After trial completed it is obvious that the overall impact of Nualgi Foliar as anadded
material will increase the plants coloring and yield. We feel a major player for this is the size
of the material as well as the essential nutrients that are often overlooked in a crop cycle.
While we feel that over applications of synthetic based nutrients deplete the soil profileof
the carbon chain molecules and strips bonds therefor causing depletion of nutrients and the
need forever increasing amount of materials the addition of Nualgi Foliar will helpsustain
plant growth and overall health. This is due to the active elements inside thematerials,
which help increase photosynthesis and enables the plants to absorb more CO2. This in turn
increases liquid based carbons in the plant and allows for more translocation and a healthier
more robust plant.
Quality of Crop: The overall impact of Nualgi on the crop itself is simply undeniable. What
we can see with the addition of NF there is a decrease in plant stress and an increase of
rigidity of the plant. This helps the plant to increase respiration and photosynthesis. NF as
an add it to a program can allow growers to increase the plants ability to grow and therefor
is a beneficial add to a grower basedprogram.

12. Effects on Yield: After reviewing the harvest records the GS + NF had an increase in quality
and overall yield of 14.99%. That equated to enough of a revenue increase based on crop
sales alone to cover the price of theapplications.
