Efficacy of Cool Terra®

The efficacy of Cool Planet’s Engineered Biocarbon™ technology has been demonstrated through hundreds of experiments and R&D trials, both internally and with external independent third-party researchers.

Rather than making claims with limited evidence, we are bringing our products to market by following the traditional, proven path used successfully by other successful agricultural products, namely:

  • Deep internal scientific trials to refine and advance technology and understanding of mechanisms
  • University and private research trials to prove efficacy
  • Distribution, key influencer and grower trials/demos to demonstrate value
  • Partnerships developed with Industry Distribution and Technology Partners with wide-ranging capabilities

Improved Water-Holding Capacity

In many environments, Cool Terra® has the ability to optimize water-holding capacity, lessen evaporative water loss and, most importantly, increase plant “available” water – the water that plant roots can actually access – when compared to controls. For growers who desire to be more efficient with water, Cool Terra® can be a highly effective tool to help your soil do more with less.

Fertilizer and Nutrient Efficiency

Cool Planet’s Engineered Biocarbon™ technology has demonstrated an ability to allow for greater fertilizer and nutrient efficiency. Our Demetra treatment process increases the cationic and anionic exchange capacity (CEC and AEC) of raw biochar, enabling soil to more effectively hold externally applied nutrition in the root zone, as well as allowing the plant to uptake nutrition more effectively. Additionally, the material creates a more favorable environment for microbial development, which can further assist with both nutrient cycling and availability in the soil. For growers who desire to be more efficient with nutrition, Cool Terra® can play a major part in a nutrition efficiency plan.

Increased Biological Life

Multiple experiments indicate that Cool Terra® can have a significant impact on the soil microbiome. Bacteria and fungi essential for soil and plant health have been observed to thrive and grow more effectively when Cool Terra® is applied. This comes as no surprise to us: We have engineered the product to have many the properties that microbes find desirable.

Increased Plant Yield

The impact of Engineered Biocarbon™ technology on water, nutrition and biological life in the soil generally can lead to improved root growth and, in many cases, improved marketable yields for growers.

This diagram shows improved root development in Cool Terra® treatment blocks when compared to an untreated soil and a soil treated with “raw” biochar, which is the same material but without receiving our Demetra treatment process. The root biomass weight was 55% greater with Cool Terra® than the comparisons after 21 days of greenhouse growth. The results were observed over multiple replicates at a statistically significant level.


Strawberry Plant Productity

In this chart we see the results of a third-party trial in strawberry production under grower standard conditions and water/nutrition deficient conditions. The yield improvements vary depending on the treatment block, but the conclusion by the independent third-party researcher was that the use of Cool Terra® “always brought improvements to the production pattern they were added to.


Tomato Plant Productivity

This chart shows the results of a third party independent field trial in tomatoes in California, demonstrating an increase in yields with improved fertilizer efficiency using Cool Terra®.
