Yield gains, denser stands, and improved nitrogen-use efficiency signal broad value across commodity, horticultural and specialty crop systems

NutriHarvest is sharing field trial results showing that its OMRI-listed organic fertiliser delivered yield gains and denser stands in corn, along with improved nutrient retention and reduced nitrate loss potential.

NutriHarvest offers organic plant growth nutrition solutions that support vigorous growth across commodity crops, horticulture; and specialty crop systems, with a focus on improved nutrient retention to help protect water quality. The results provide growers and partners with a practical benchmark for seasonal planning, especially for high-demand crops where steady nutrient delivery and soil health are critical. These findings come from independent field trials conducted by a leading Northeast university Extension program.

Corn as a Model for High-Demand Crops
Corn is one of the most widely grown crops in the United States and globally, making it a common benchmark for fertilisser performance. USDA’s latest outlook estimates 2025/26 U.S. corn production at 17.0 billion bushels and global production at about 1,296 million metric tons. Because of its high nutrient demand and sensitivity to nitrogen availability, corn is widely used to assess fertilizer behavior relevant to commodity, horticultural, and specialty crop systems.

Trial Design and Key Results
In independent corn field trials, Extension researchers compared NutriHarvest fertilizer with a leading organic commercial fertilizer, chemical commercial fertiliser and an untreated control. Application rates were adjusted so that each fertilised treatment delivered 100 pounds of nitrogen per acre, ensuring a fair, nitrogen-equivalent comparison.

In these Extension corn trials, NutriHarvest performed comparably to chemical commercial and leading organic fertiliser benchmarks while delivering advantages in yield and soil nutrient retention. The results indicate a balanced, slow-release nutrient profile that supports productivity while improving nitrogen-use efficiency and reducing nitrate loss potential.
