The research and discovery teams at Nutrien Ag Solutions® have dedicated tremendous resources to understanding how seaweed extracts can benefit your crop systems and utilized this information to develop the next generation of kelp science—Maritime™. Maritime is designed for use with specialty crops such as almonds, grapes, citrus, strawberries, broccoli, lettuce and more.

How Maritime Works

Maritime augments a balanced crop nutrition system by stimulating soil microbiota, improving plant health and aiding plant response during periods of stress. Our scientists identified the naturally occurring compounds in kelp which are responsible for the plant health effects typically associated with seaweed extract applications. This optimized, revolutionary extraction system creates a finished product unlike any other on the market. Maritime has a higher concentration of key bio-active compounds which can help improve crop quality, reduce crop stress and contribute to better soil health in specialty crops.

Take a quick look at the science that sets Maritime apart from traditional competitors.

The Power of Maritime


2018 University of Arizona Farming Grounds Commercial Lettuce & Pepper Trials





Lettuce Chlorophyll Ratings & Yield (Tons/Acre)

Lettuce Harvest (Total box/acre)

From our test plots in Yuma, Arizona, to your fields in Anywhereville, USA, Maritime has outperformed competitive products and given growers real results they can see each growing season.

Pepper Nutrient Uptake (mg/100g) & Yield (Lbs/Acre)

Maritime in the Field

Maritime Dilutions With CAN-17


Maritime blends with fertilizers and soil amendments without sedimentation or solids creating issues.

Drought Soil Study

After a recent drought soil study, Maritime delivered results in three phases—with healthy plants, through a drought simulation and in plant recovery.

Healthy plants were treated with Maritime at 4 quarts per acre, water, competitive seaweed at 2 quarts per acre and Maritime at 1 quart per acre.

Drought simulation had water withheld to simulate drought following the application of materials.

Recovery was seen after precipitation was simulated.

Seedling Germination Demonstration

After a recent seedling germination demonstration in a saline environment, Maritime helped contribute to better results than a competitive seaweed at 2 quarts per acre or from using water alone.
