The biostimulants market is expanding rapidly, becoming more professional and offering potential for growers, according to a new research review.
AHDB Cereals & Oilseeds, which funded and published the review, said although product diversity made the process of detecting significant benefits challenging, some positive yield results were identified in cereal experiments.
The term ‘biostimulant’ covers anything added to the plant or soil that stimulates natural processes which benefit crops – excluding any fertilisation and pesticidal action.
For the most common product categories – seaweed extracts, humic substances, phosphite and plant growth promoting bacteria – statistically significant yield responses were observed for 3/7, 3/4, 4/17 and 13/15 cereal experiments, respectively, according to AHDB.
Data for oilseed rape was found to be lacking for all products and no firm conclusions could be drawn, it added.
