Every Drop Counts: How Surf-Max® Greatly Reduces Water Usage

Water scarcity is THE issue driving western agriculture. In California, the world’s food basket relies heavily on irrigation to annually grow 9.6 million acres of fruits, nuts and vegetables. As complex water allocations continue to pose significant crop production challenges, growers must make every drop count.

Now, help is on the way, with recent state registrations of Huma’s water optimizer Surf-Max^®.

Our distributor in Spain recently reported on the effectiveness of Surf-Max with seven years of extensive data. Not only does Surf-Max provide significant water savings, it subsequently builds a better, healthier, and more nutritious crop.

• Processing Tomatoes: In sandy soil, growers achieved a 15% reduction in irrigation allocation without sacrificing health. Not only was there an improvement in color and growth (shown in the photo below), but nutrient levels skyrocketed. Increase of N was 3.7%, P was 50%, K was 6%, Ca was 5%, Iron was 11%, Manganese was 17%, Zinc was 6%, Copper was 28%, and Boron was 2%.

Surf Max

• Lettuce: Surf-Max reduced irrigation water applied by 22% with a water savings of 8,500 ft³/ac. That’s 63,000 gallons worth!
• Arbequina Olives: Growers maintained their full yield even when water allocation was cut to only 80% of the control volume.
• Iceberg Lettuce: Trials showed a 7.8% production increase and a 10.5% reduction in collar rot because water was managed properly rather than sitting in excess around the plant neck.
• Monalisa Potato: Continuous application led to a massive boost in quality. Yield increased 8% and starch increased an extra 2.5%, a critical metric for potato growers.
• Broccoli (trial 1): Yield increased 3.5%, water reduced 10%, and average surface tension reduced 37%.
• Broccoli (trial 2): Irrigation reduced 30% and soil water tension reduced 1.4%.

It’s also about uniformity. In the broccoli and tomato trials, they didn’t just see “more” crop; they saw the field mature at the same rate. For a grower, a concentrated harvest window is pure profit. It means fewer passes with the harvester, reduced labor costs, and a much higher commercial pack-out.

What Exactly is Surf-Max?

Surf-Max isn’t just another wetting agent. It is a sophisticated soil surfactant that represents years of intensive development to ensure it performs under the toughest field and tank conditions. What defines this as a “next-gen” surfactant is its total compatibility. Most conventional surfactants are finicky; they “salt out,” precipitate, or create clogs when mixed with fertilizers or organic materials. Surf-Max is designed to be a carrier. Because it is stable when mixed with nutrients, probiotics, and organic fertilizers, it allows farmers to perform two tasks at once—irrigation and nutrition—without the risk of biofilm formation or emitter clogging.

The biological impact of Surf-Max goes beyond mere hydration. In modern agriculture, we often forget that roots need to breathe as much as they need to drink. By managing surface tension, Surf-Max facilitates the creation of oxygen-rich micropores within the soil. This maximizes the ROI of every fertigation cycle. We shift from “watering the plants” to “managing the physics (and biology) of the soil”.

Furthermore, the product is built for the environmentally conscious producer. It is highly biodegradable, breaking down within 4 to 21 days, and has no negative impact on soil microbial fauna. It works in harmony with beneficial microbiota, such as mycorrhizae and plant growth-promoting bacteria, ensuring that the ground remains fertile for the long haul.

To understand why this product is a gamechanger, we have to look at the physics of water. Pure water has a surface tension of approximately 72.8 mN/m. This tension is what causes water to “bead up” and resist entering tight soil pores. Surf-Max shatters that tension, reducing it to less than 30 mN/m.

The Secret is in the MCT

The “secret sauce” is our proprietary Micro Carbon Technology^® (MCT). In simple terms, MCT is a subfraction of fulvic acid, which means it has a much higher molecular surface area and a higher exchange capacity than standard humates. These highly oxygenated carbon rings act as a high-tech carrier. While conventional surfactants might do some good, the MCT in Surf-Max ensures the product doesn’t just wet the top inch; it carries the solution deep into the soil profile and keeps it bioavailable exactly where the roots are.

Two years ago we did a university study to showcase Surf-Max. The results came out showing that Surf-Max worked very well, just as good as the top contender. Significantly different from the control (no surfactant, but not significantly different from the leading contender. I wasn’t too excited about the results until a video call with the Extension agent a few days later. He was astounded at the strength of Surf-Max and praised its performance. As he went further into the data, he mentioned that the leading surfactant was applied at 10x the rate of Surf-Max and it was 3 times the cost! Now I understood the significance of the not “significant” data. And now I know… the rest of the story.

Surf-Max powered by Micro Carbon Technology is a strong, cost-effective water optimizer to apply in every irrigation cycle. Surf-Max is the perfect tank mix partner which aids with water use efficiency, improving water retention and therefore increasing yields, nutrition into the plant, and crop quality. Not only does it help with making water wetter, but it also benefits the crop protection and fertility products in the tank and builds the microbial population and the soil structure. Surf-Max truly makes every drop count.
