Why use a Carbon Source Biostimulant?

Biostimulants were first commercialized in the 1950’s when seaweeds extracts started showing a “hormonal” response to the plant. Over the next 2 decades protein hydrolysates and humic acids were commercialized, but we only knew what these products did to the plant and NOT how they worked. 

In the last 20 years, with the advancements in analytics, extraction techniques, and RNA sequencing we are now able to determine the key compounds and how they work within the plant. 

The Carbon Source family was originally referred to as Humic acids. With advancements, the family now includes fulvic acid, and PPA (polymeric poly hydroxy acid) that contain compounds such as polyphenols, tannins, lignins, humin and lipids.

Why Transit?

Transit-S Technology, exclusive to ATP, is a patented technology that works in the plant to drive respiration. Increased respiration helps to drive rooting, improve nutrient use efficiency and alleviate stress.

  • Increases rooting.
  • Increases respiration and metabolism.
  • Superior uptake of applied nutrients.
  • Increases yield and backed by over 1100 independent replicated trials.
  • Backed by the Transit-S Technology Performance Guarantee.
  • CFIA registered for seed, soil and foliar application.
  • Can be applied to a wide range of crops.
  • Compatible and complimentary to a wide range of nutrients.
  • Transit-S is formulated into key ATP products, including PreCede, ReLeaf, Kinetic and N-Fluence.

Proven Agronomic Performance

  • WinRhizo results from 15 field trails conducted in 2013 to 2014 report Transit-S enhanced the root architecture among crops, showing as much as a 92% increase in the root surface area in Peas, when foliar-applied.
  • Root analysis collected from 3 years of field trials show that in addition to increasing the root surface area, a 70% increase in the number of nodules was observed in Transit-S treated soybean plants.
  • Data from 11 field trials between 2013 and 2014 show a consistent increase in yield in Canola, Wheat, Soybeans and Peas. The addition of Transit-S enhanced productivity by 4.5 bu/ac and 5.1 bu/ac in Soybeans and Peas, respectively.

Product Recommendations:

For Application with Fertilizer:

  • Apply Transit-S at 200 ml/ac with your liquid in-furrow or starter fertilizers.
  • Granular Fertilizers – Impregnate 1-4 L of Transit-S onto each ton of dry fertilizer, depending on the final rate of fertilizer application in the soil.
  • Foliar Application – Apply 100 ml/ac of Transit-S with your fertilizers and pesticides.

For Application with Seed:

  • To maintain uniform coverage on the seed, you may dilute with water. 
  • Allow for proper drying time to ensure optimum flowability.
  • Do not treat directly into planter.
  • If combined with a seed protectant, conduct a jar test and refer to ATP ’s information on product compatibility and calibration at
  • Once Transit-S is combined with a seed protection, the mix shoud be applied as soon as possible.
