Symbios Bio-Fertility Amendments


Reforestation Technologies is the largest and oldest provider of premium mycorrhizal inoculants in the country.  Quality and consistency are the key values that have helped the company move to the forefront as a supplier and formulator of arbuscular mycorrhizal inoculants. Recently, the company introduced another beneficial microbe, Azospirillum ssp., nitrogen-fixing bacteria. Our business has been built by supplying biology to some of the toughest mining reclamation and habitat restoration sites on the continent. Our track record speaks for itself as several of our very first customers that started with us in the mid 90’s are still with us. We pride ourselves on the quality and consistency of our products. We invite any interested commercial parties to visit our facilities to better understand how we can exceed the highest standards of commercial Inoculant production.

Proof of Purity and Origin


Each species of arbuscular mycorrhizal fungi were acquired from two of the internationally recognized sources of pure mycorrhizal germplasm, INVAM (, operated by the University of West Virginia, and GINCO (, jointly operated by the governments of Canada and Belgium.  

Greenhouse & Laboratory Research


RTI’s research focus is on beneficial microbial and bio-stimulant products, their performance by crop and any interactions (both positively and negatively) that may occur.  The company operates a 3,500 sq. ft. state of the art greenhouse as well as 7,000 sq ft. of fabric covered open sites for outdoor trials. Our greenhouse and laboratory facilities provide a unique opportunity to offer a range of research and analytical services to companies wishing to examine crop and soil biological assessments.  The climate of Gilroy, Ca is moderated by its close proximity to the Pacific Ocean which is about 20 miles. The proximity keeps daytime temperature in the 70 F / 23 C range for most of the year, dipping in the winter to nighttime lows near freezing and midsummer days to the low 90s F / +32 C.  An abundance of non-chlorinated water is available from a well on the property that delivers a premium quality source for both drinking and irrigation needs.  Filtered reverse osmosis water is also available for certain types of evaluation. 

Quality Control Lab


Each batch of RTI’s biologicals is individually tested to assure that the product meets standards for infectivity potential (number of propagules), cleanliness and viability.


RTI is the only producer of mycorrhizal inoculants in America that sets and meets these rigorous standards.

Independent Laboratory Analysis Reports


Spore and propagule counts are tested internally to assure that all inoculum meets the infectivity potential claimed on the label. An third-party laboratory analysis is also used by RTI to verify standards.
