For those who can attain improved soil quality and biological productivity, research shows a positive impact on leafy green yields.  For example, Knight et al., (2012) report that lettuce dry biomass was positively correlated with several indicators of improved soil health and quality (e.g., soil organic matter %, among others) in soil systems that have received considerable disturbance.

To facilitate soil health in lettuce production and the production of other leafy greens, Heliae’s product family, PhycoTerra® and PhycoTerra® Organic, provide a microbial superfood and can be readily deployed on your field to help improve soil health and soil quality today. Heliae research shows that application of PhycoTerra® products can help improve the soil microbiome by providing a labile food source which can lead to improvements in soil structure and water holding capacity.
