Biostimulants

Plant biostimulants are products that contain substances and/or micro-organisms whose function when applied to plants or the soil is to stimulate natural processes independently of the product’s nutrient content in order to enhance or benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, yield and crop quality.

Plant biostimulants are an important tool for sustainable agriculture due to their ability to enhance tolerance to abiotic stress, nutrient use efficiency, crop performance and quality. They are complementary to mineral fertilizers by improving their effect through the improved availability, assimilation, translocation and use of plant nutrients to the plants. Plant biostimulation is thus part of the 4R nutrient stewardship toolbox available to farmers.
