The Clarus product line complies with standards set by the U.S. Environmental Protection Agency, the U.S. Department of Agriculture National Organic Program and American Association of Plant Food Control Officials.


A long term study conducted by an accredited research institution establishes the scientific data permitting Nutrients PLUS to claim the Clarus brand as an Enhanced Efficiency Fertilizer, an official regulatory term with criteria that requires a fertilizer to possess properties that reduce the loss of nutrients into the environment, increase nutrient availability for uptake by plants and data to support those claims.


In March, Encina Wastewater Authority (EWA), a public agency based in Carlsbad CA, announces a unique public-private joint venture that elevates the standards and safety requirements for treating and using biosolids as fertilizer. EWA has been developing and producing a nationally recognized Class A Exceptional Quality fertilizer for over 9 years.
