Acadian Plant Health™ (APH™) seaweed extract produces plants with full, well-developed root systems that are better able to take advantage of available water and key nutrients. It promotes the synthesis of natural compounds, including betaines and proline, that protect against cellular damage from stresses and reduce pod abortion. Plants that grow strong root systems, take up more key nutrients, and resist stress well will yield to their full potential.
BENEFITS FOR SOYBEANS INCLUDE:
- Improved root growth and plant establishment
- Enhanced abiotic stress resistance
- Decreased pod abortion
- Increased yield
SCIENTIFICALLY PROVEN, FIELD-TESTED SOLUTIONS
IMPROVED ROOT GROWTH
DEMONSTRATION SOYBEAN TRIAL
NORTH DAKOTA, UNITED STATES
After just one application of APH™ seaweed extract, the treated soybean plants had visibly longer roots and more lateral roots. This means a larger absorption area for more efficient nutrient uptake.
IMPROVED ABIOTIC STRESS RESISTANCE
SOYBEAN TRIAL ‘SAVANA’
NOVA SCOTIA, CANADA
We conducted a test in which we withheld water from soy plants for a total of five days. Over the five-day period, we captured images (shown below) with an infrared camera. The colours at the blue end of the spectrum indicate cooler temperatures; the pictures show that the soy plants treated with APH™ seaweed extract withstand drought stress better than Control plants.
Day 1 – There is no difference in transpiration between the treatments prior to withholding water. Both plants are cooler than their environment.
Day 3 – The Control plant wilts and its leaf temperature increases while treated plant is more turgid and has cooler leaf temperature.
Day 4 – Both plants appear wilted, but the leaf temperature is higher in the Control plant (red/white colour). The upper leaves of the Control plant will not recover from the stress.
Day 6 – One day after re-watering, the stomata of the treated plant opened sooner than that of the Control plant; the treated plant is cooler (blue colour) and carbon dioxide can enter it to resume photosynthesis and carbohydrate assimilation.

DECREASED POD ABORTION
SOYBEAN TRIAL ‘INTACTA’
Stressed soybeans tend to abort their pods. When plants were treated with APH™ seaweed extract, the abortion was reduced by 11 percentage points indicating that plants treated with APH™ seaweed extract tolerate the stresses better and can carry the pods to harvest.
Thirty-eight replicated and demonstration trials on soybeans were conducted between 2012 and 2016 in Indiana, Iowa, Michigan, North Carolina, Tennessee and Wisconsin. The addition of APH™ seaweed extract to the standard program (Control) consistently increased yield, with an average increase of 9%.
