Helping the world grow the food it needs is core to everything we do at Mosaic, but so is our focus to do it responsibly. We know that we share in the responsibility of reducing the environmental impacts of fertilizer. That’s why it is important to us that two of our products, MicroEssentials^® and Sus-Terra™ fertilizer by The Mosaic Company are now labeled as Enhanced Efficiency Fertilizers (EEF) as defined by the Association of American Plant Food Control Officials (AAPFCO). 

EEF products reduce nutrient losses to the environment through the slow release of nutrients or by disrupting the conversion of nutrient forms in the soil that are susceptible to loss all while increasing nutrient availability for the crop. Innovative fertilizers, like EEFs, are an important component of 4R Nutrient Stewardship. Combined with 4R practices, the use of EEFs and other emerging technologies will help to promote more sustainable farming practices while also solving for the world's increasing demand in food supply.

MicroEssentials and Sus-Terra fertilizers EEF designation support Mosaic’s continued efforts to provide next-generation crop nutrition to meet today’s yield demands and help ensure legacy of land for generations to come. During a recent IFA webinar, Dr. Claudia Wagner-Riddle (University of Guelph and 2020 IFA Norman Borlaug Award recipient) and Dr. Tom Bruulsema (Plant Nutrition Canada) underscored the need to minimize N2O emissions from agricultural fields through the use of nitrogen inhibitors and EEFs. Key findings from the Canadian 4R Research Network found that the use of EEFs allow growers to reduce emissions up to fifty-five percent. 

About MicroEssentials
Through its patented Fusion® technology, four key nutrients are combined into a single granular – including two forms of sulfur. MicroEssentials meets EEF standards as a slow-release fertilizer by offering 50% of the total sulfur as Elemental Sulfur.

About Sus-Terra Fertilizer
In 2020, Mosaic launched a partnership with Anuvia to produce products that would also support healthy soils with the development of Sus-Terra fertilizer. Sus-Terra fertilizer is a first-of-its-kind product that transforms recycled organic matter into a powerful phosphate-based, single granular fertilizer. The unique chemical composition of Sus-Terra fertilizer, built with up to 15% recycled organic matter, promotes a more balanced microbiome to support soil health. In addition, its 30% slow-release nitrogen meets the required designation as an EEF.
