Plant Biostimulants

Plant biostimulants are an important tool for modern agriculture as part of an integrated crop management (ICM) system; helping make agriculture more sustainable and resilient.

According to EBIC (European Biostimulants Industry Council) plant biostimulants contain substance(s) and/or microorganisms whose function when applied to plants or the rhizosphere, is to stimulate natural processes to enhance plant nutrient uptake, nutrient use efficiency, tolerance to abiotic stress, and crop quality.

Plant biostimulants differ from other agricultural inputs such as fertilizers and plant protection products because they utilize different mechanisms and work regardless of the presence of nutrients in the products. They also do not have any direct action against pests or diseases and therefore complement the use of fertilizers and plant protection products.

BIOTRYG™ - biostimulant technology for improved crop performance

BIOTRYG is the global brand name for Yara's biostimulant technology.

The name "BIOTRYG" is a combination of "bio", representing the biostimulants platform, the plant's natural process and life; and the Old Norse word "tryggr", which means trust, faithful, and also reminds us of the English word "trigger", representing the effect of the technology on the plants.

BIOTRYG™ technology improves:

  • Nutrient use efficiency
  • Tolerance to abiotic stress
  • Crop quality

BIOTRYG™ technology complements Yara’s complete range of high-quality and innovative crop nutrition solutions. Applied when the crop most needs it, it works in synergy to keep the farmer’s business profitable and sustainable.

Our product range

YaraVita PROCOTE RHIZOLIFT product packaging
YaraVita PROCOTE RHIZOLIFT™ is developed for coating granular fertilizer. It is designed to work in the rhizosphere of the plant root to increase the phosphorus availability and uptake which enhances crop establishment. Moreover it improves the plants' response to abiotic stress conditions in the early growth stages. YaraVita PROCOTE RHIZOLIFT is the most efficient way to apply biostimulants to a plant through a fertilizer coating application.
YaraVita NRHIZO product packaging
YaraVita NRHIZO™
YaraVita NRHIZO™ is a tailormade solution for legume seed treatment designed to optimize crop establishment and enhance root growth, improving water and nutrient use efficiency. The innovative solution enhances the N-fixation and alleviates the impact of abiotic stress at early stages.
YaraVita Biotrac packaging
YaraVita BIOTRAC™ is a liquid formulation for foliar applications based on a blend of nutrients and bioactive components extracted from the algae Ascophyllum nodosum. It was developed to alleviate the impact of abiotic stress conditions (e.g. cold and drought) and help the plant during periods of high metabolic demand in order to enhance flowering, fruit set and improve yield quality and quantity.
YaraVita Biomaris packaging
YaraVita BioMaris™ is a highly concentrated liquid formulation for foliar applications based on bioactive compounds extracted from the algae Ascophyllum nodosum. Due to its high concentration of bioactive compounds, BioMaris™ can be used to promote plant growth and fruit development, and it can also mitigate the effect of abiotic stress.
YaraVita BioNUE packaging
YaraVita BIONUE™
YaraVita BioNUE™ is a suspension concentrate formulation for foliar and soil applications based on a blend of nutrients and humic substances from leonardite. It was developed to enhance tolerance to abiotic stress, increase nutrient uptake, root and vegetative growth and improve the structure and efficiency of the rhizosphere. ​
YaraVita ACTISIL packaging
YaraVita ACTISIL™ is a liquid formulation for foliar applications based on choline-stabilized orthosilicic acid (ch-OSA®) and Calcium. It was developed to help the plant to remain vigorous in hostile growing conditions in order to improve yield quality and quantity.
YaraVita Seedlift packaging
YaraVita SeedLift™ is a suspension concentrate formulated with a balance of nutrients intended to promote seed germination and deliver the starting nutrients that are required in the early stages of growth in most crops. The addition of bioactive compounds from Ascophyllum nodosum is intended to strengthen plant resistance to abiotic stress conditions and help young plant development.
