Trial Results

We've been conducting farm-scale trials in many crops since 2019.  Many results are reported in our blog and documents posted here. Pacific Gro is a core input in organic programs and also in conventional programs that include biological practices.   Our trials use biological soil analysis (Solvita and Biome-Makers) to document improved soil health and microbe diversity, and Leaf Extract Analysis (by Apical Crop Science) to document nutrient balance and uptake.

Strawberries:  Pacific Gro was used on 800 acres of strawberries on the California central coast in 2019, in a conventional program at rates of 8 to 15 gal/acre during the crop season.  Yield increased 20% to over 80% - from an average of 26 tons/acre in 2018 to 32 to 48 tons/acre in 2019.  These strawberry growers (and others) have since added Pacific Gro to their programs.

Corn trials focused on soil health have been conducted in Iowa, Nebraska, Wisconsin and Ohio.  A grower in Nebraska found higher nitrogen in the plants, and better yield, by reducing the synthetic nitrogen and using Pacific Gro to get the soil microbes to provide nitrogen to the crop.  Continuum Ag has done a two year trial in Ohio, in a conventional corn / soybean rotation. Pacific Gro proved effective improving soil health and plant health at very modest cost per acre. A 2021 organic corn trial in Wisconsin showed superior results combining Pacific Gro and QLF TerraFed.  The 3 treatments with this combination averaged 10% more yield (240 bushels organic corn) than treatments without both inputs. 

Grapes:  Pacific Gro has improved soil health, the appearance and vigor of vines, and the brix of grapes at many large vineyards in Napa, Sonoma and the California central coast.  A trial summary report is linked below.

Wheat, canola and cover crop trials are in progress, dryland farmed in the Palouse of eastern Washington, by a group of farmers determined to restore the region's fertility.

We also have extensive experience in apples, cherries and berries grown in both organic and conventional programs.   Pacific Gro is known to move more Calcium into the fruit - which is critical for fruit quality and shelf life.
