Valena- OMRI-LISTED®, Novel Fertilizer 


Primes Soil with Novel Plant Growth Technology

Growers are continuously seeking new sustainable ways to improve the health and growth of their crops. Especially young plant growers who are often at the forefront of the plant industry regarding the latest growing techniques and market trends.

At Kemin, our approach to plant health consists of giving them a great start. We believe that maximizing the potential of the growing environment where a plant grows is a more powerful option. That is why we developed Valena™.

Valena is a new generation of OMRI-Listed® fertilizer that goes beyond N.P.K nutrients. Valena is a dry powder to use at seedling or transplant that primes the growing media with a unique source of 1,3-β-glucan material derived from Kemin’s sustainable microalgae Euglena gracilis known to elicit plants’ defense responses.

Valena top dressed or soil amended, helps promote higher quality plants and crop yield, and helps with an earlier transplant.

Valena is a great sustainable alternative to traditional liquid fertilizers or biostimulants to help growers upgrade their nutritional program and reach their farming potential.

Euglena Gracilis - Kemin's Sustainable Material For Plant Growth


  • β-glucan.....................................>50%
  • Total Nitrogen (N) .......................>2%
  • Total Phosphorus (P2O5) ..........>1%
  • Total Potassium (K2O) ................>1%


Unlike other β-glucan, our 1,3-β-glucan is unique to Euglena and has the highest purity form currently available on the market, with a concentration of fifty percent compared to other types of glucans (i.e. laminarin 2-9%) extracted from other sources.

Sites for Use

Young Plant Greenhouse Growers

Young plant growers deserve a high-quality media foundation to ensure with full confidence the product they offer is of consistent quality, uniformity, and vigor. Valena is highly recommended for the production of large quantities of plugs, cuttings and other greenhouse-grown ornamental plants. 

Fruit & Vegetable Growers

Commercial growers must keep their business as profitable as possible. Valena is an environmentally friendly and sustainable material that is essential to help increase field-grown fruit and vegetable crop yield.

Growing Media Manufacturers

Growing media manufacturers must distinguish their brand from the pack. Valena is a first-class innovative ingredient to develop new formulas for professional all-purpose, potting or propagation mixes.

Smart Mode of Action

Valena Modes of Action

Valena has a unique mode of action. When incorporated into the growing media, it breaks down and releases its active ingredients 1,3-β-glucan, known to elicit plants’ defense responses.

Scientific research showed that substances like 1,3-β-glucan are viewed as Pathogen-Associated Molecular Patterns (PAMPs) by Pattern Recognition Receptors (PRRs)1-4 present naturally in plant cells, meaning that the presence of Valena in the soil can be mistaken for pathogens3,5,6 by the plant.

Normally, a plant increases nutrient uptake to fight off potential pathogens. However, when there is an increase in nutrient uptake with no real pathogenic threat, the growing media has been primed to encourage the nutritional uptake favorable to plant growth7-9.

Greenhouse & Field Trials

Vinca trial Valena

31 days after planting (31 DAP), the Vinca plugs treated with Valena look significantly fuller and greener compared to the untreated plugs.

Vinca trial Valena 2

Not only did the Valena-treated vinca plugs thrive, but they were also as big as the control plugs even when sown 11 days later!
