Use PhycoTerra® to Boost Broccoli and Cauliflower Yields

Research Trials Conducted in Yuma, AZ Reveal the Marked Soil Health and Yield Improvement Gained Through the Application of PhycoTerra® or PhycoTerra® Organic.

2018 Broccoli Trial in Yuma, AZ


Broccoli and cauliflower yields improved significantly when PhycoTerra® was applied. A 1-quart per acre application boosted yields by as much as 15%, while a 2-quart per acre application rate optimized yields by 19%.

Nutrient cycling, with increased calcium and nitrogen uptake by the plants, was also improved with the addition of PhycoTerra®.

PhycoTerra® produced both cauliflower and broccoli heads that performed and yielded above grower standard.

PhycoTerra® Helps Maintain Soil Health and Increase Yields

Maintaining soil health within a commercial broccoli or cauliflower operation is challenging. Common production model practices such as tillage, bed listing and fumigation reduces biological activity, and crop production regulations make it difficult to incorporate many of the recognized soil quality and capacity building practices.

PhycoTerra® and PhycoTerra® Organic improve the soil health opportunities growers have at their disposal. Both provide the microbial superfood needed to attract and maintain a diverse colonization of microbial activity—the foundation of soil health— that create the soil aggregates needed to improve soil structure and water holding capacity.

And both products can be readily deployed on a field at any time to provide measurable soil health and soil quality almost immediately.

The Proof is in the Research

PhycoTerra® Soil Amendment performance was recently tested at two different rates in a broccoli production system near Yuma, AZ on soils with both low natural fertility and excessive drainage.

Despite these challenges, the application of PhycoTerra® with a common orthophosphate starter mix improved yields by ~14% (1 qt./ac) and ~17% (2 qt./acre) compared to the grower standard.

Soil quality, improved by PhycoTerra®, increases crop yield and resilience to growing challenges.
