We have rigorously tested PhycoTerra® in professional and academic field trials, internal greenhouse studies, and with growers throughout the US and abroad.  Remarkable results have been observed when using PhycoTerra®:  from improved root development to early germination and increased plant fresh weight and marketable fruit yield.  Here we present a selection of data and results from our recent tests with this first in class agricultural product.



Our Phase I trial was conducted by Holden Research and Consulting in the 2014 growing season on bell peppers grown in Southern California. Our expert panel chose bell peppers to test the ability of PhycoTerra® to improve the growth of plants in the pepper family.

As a liquid product, PhycoTerra® was applied through the use of standard irrigation equipment (see our label for recommended directions for use). This trial was set up as a block design study of eight replicates to evaluate the effects of the NPK* and watering program compared to the same program overlaid with PhycoTerra®.

Results have been confirmed by growers in a number of pepper varieties including bell, jalepeno and chili peppers.

As shown in the graph, the research and development team observed an increase in marketable** peppers on areas treated with PhycoTerra® and NPK.

*NPK media consisted of a conventional NPK ratio of 3:1:3.

**Utilization is the ratio of marketable to total yield as determined by Holden Research and Consulting, an independent agricultural research organization.

Kidney Beans

Field trials of PhycoTerra® have also shown yield enhancement when the product is used in beans. Grower photos from some of the first applications of the product in 2014 demonstrate positive results in kidney beans.


A field trial on peanuts was conducted by a US-based university in 2015. Peanuts are an important, environmentally sensitive crop in the legume family. Results showed that application of PhycoTerra® resulted in a 30% increase in growth and yield in peanut plants.

As a liquid product, PhycoTerra® was applied through the use of standard irrigation equipment. This was a controlled trial to evaluate the effects of untreated plants with those provided with PhycoTerra®.

The study demonstrated that treatment increased overall plant biomass as well as total peanut yield (graph provided).



A controlled study in tomato seed germination was conducted by Holden Research and Consulting to evaluate the efficacy of PhycoTerra® on influencing the speed and completeness of germination when used as an initial soil drench.

PhycoTerra® treated seeds demonstrated earlier seed germination and seedling emergence than water alone. Note, however, that when the study was carried forward (off protocol) through to fruiting, there was no measurable difference in yield between treated and untreated groups.


2015 grower field data on potatoes grown Idaho, obtained through our distribution partner AgroDyne demonstrated early emergence of potato plants treated with PhycoTerra® as compared with those receiving the grower’s standard treatment protocol. PhycoTerra® was applied in-furrow at the recommended application rate.

Consistent differences continued throughout the life cycle of the potato plants.


We believe PhycoTerra® is effective at enhancing yield and emergence in many crops and conditions.

There are still much we can learn about this exciting product. To this end, we continue to perform additional studies. Follow our progress by connecting with us.
