SRP on Soybeans

We have been working with soybean producers across North America, and have consistently witnessed better root growth, biomass and yield. In 2023, we took a closer look at our SRP product exclusively for soybeans by completing replicated trials with Eurofins Agrisciences and performing in-house greenhouse trials.

Eurofins Agroscience Services is particularly known for its expertise in agrochemical testing and regulatory consultancy. Capabilities include:

  • Extensive Experience: Eurofins Agroscience Services has over 30 years of experience in crop protection. This long-standing history in the field signifies a deep understanding of agricultural practices and challenges​​.

  • Wide Range of Services: They provide analytical, regulatory, and field support to a variety of sectors within agriculture, including agrochemical, bio-pesticide, biocide, and fine chemical manufacturers, as well as plant breeders. 

  • Global Reach and Expertise: Eurofins Agroscience Services operates on a global scale, indicating their capability to handle diverse agricultural conditions and regulations in different regions

Trial Project details:

  • Seed: Glycine max (GLXMA)

  • Evaluated yield using 4 different AdvancedAg formulations vs control

  • With 5 treatments including control, 4 replications performed per treatment, thus a 20 treatment randomized complete block design

  • Each plot was a 10 x 20 ft zone, and the harvested area was the two inner rows

  • The soil was 39% sand, 40% silt, 21% clay, with good fertility level and good drainage  

  • Planting was performed on June 5, 2023 

  • Product dosing was performed on Jun 16, July 14, and August 4

  • A drone view of the 20 plots is shown below

  • Each application occurred at seedling, mid-vegetative, and early reproductive stage

  • Compared to control, every treatment showed increased yield of 5% to 15%

  • The 15% improvement was seen from Treatment 4, which is our SRP technology, providing a mix of biofertilizer activity, enzyme production, but is specialized for phosphorus solubilization

  • Confidence interval was 92.5%

It's important to note that the Principle Investigator, Jacob Wallbrown commented that the AdvancedAg formulas performed as well as anything Eurofins tested in 2023.  

In-House Laboratory Trial on Soybeans:

Here are some details of an extensive soybean trial ran in our greenhouse:

Statistically robust experimental design includes:

  • Typically 36 to 72 seeds per tray, and 8 to 16 trays per treatment type. 

  • Treatments are assigned to trays randomly, and once trays are set into bays, they are relocated every 48 hours (randomly)

  • Precise temperature and humidity control are exercised at all times, each tray gets identical treatment

  • Each tray is an “observation for statistical purposes,” making ANOVA and TUKEY HSD analysis possible between treatments

The picture above shows 1 bay in use, 12 trays (1020) per bay. We have a total of 12 bays available for greenhouse studies, which can handle 144 tray experiments simultaneously.

Each bay has lights adjusted to specific PAR values (photoactive radiation) as required for the plant being studied, and fans are located strategically to eliminate “hot spots”

Seeds used were Glycine Max (GLXMA) in the 2 projects.

In the 2 studies, seeds were planted at the rate of 32 per tray in a 4 x 8 grid equidistantly spaced.

In the first study, a low nutrient soil was used for all trays, while a high nutrient soil was used in the 2nd soybean greenhouse run.

There were 5 total treatments including control, plus 4 product variations

8 trays per treatment type, 5 treatments, a total of 40 soybean trays in the study, and 8 x 32 = 256 individual soybean seeds planted per treatment type. 

This was a 15-day run and covers from planting through end of seedling growth

Here were the results:

The above chart was from the low nutrient profile soil. All of the 4 product treatments performed better than the control. The best advantage was shown by Product 4 (SRP), with about 70% increase in total biomass over 15 days.

The above data is from the high nutrient soil. All 6 product treatments performed better than control. The best advantage was shown by Product 6 (SRP), with 11.2 grams per tray yield vs 7.5 grams per tray yield in the control, or a 49% increase.
