What are biostimulants?

A biostimulant is not a crop protection product, but it improves the

  • nutrient use efficiency,
  • tolerance to abiotic stress,
  • crop quality,
  • availability of confined nutrients in soil or rhizosphere

How to use the database?

The database gathers scientific data on plant biostimulants for growers. You can search generally on any search term or you can filter by desired effect, biostimulant type or crop. After searching you get an overview of biostimulants. By clicking on a biostimulant you open the data sheet with information on the biostimulant (type, company), description of the effects, trial details (greenhouse/field trial, stress conditions and country), tested crops, application (method, timing, rate) and source. 


The database is one of the goals of the Bio4safe project (2017-2021) funded by Europe via the Interreg 2 Seas Programme. Bio4safe wants to reduce water and fertilizer use in horticulture (by 20 and 10%, respectively) in the 2 Seas Region (coastal region across the southern North Sea and The Canal) by:

  • increasing the use of biostimulants and innovative plant monitoring tools to study the effect of biostimulants on plant responses
  • writing a policy protocol on how to measure the impact of biostimulants on fertilizer and water use efficiency of plants
  • creating economic opportunities for local seaweed producers by studying business cases on biostimulants based on local seaweed

The project includes demonstration trials on different horticultural crops (lettuce, tomato, Surfinia, Hydrangea, strawberry, raspberry, tulips, Chrysanthemum) in four different countries to promote the use of biostimulants to diverse target groups.

The project is coordinated by PCS Ornamental Plant Research (BE) and includes 7 other partners:
