Biostimulants are a growing trend in agriculture, with their use rapidly increasing worldwide, but there are still some questions about how they play a role in today's agriculture.   Yara's Marcio Wally, Biological Senior Manager based in Canada, explains that biologicals are complementary to traditional agricultural inputs like fertilizers and pesticides, enhancing crop nutrition and resilience to stress. Biostimulants can improve nutrient availability and uptake, as well as enhance plant aspects to resist crop stress. They do not replace nutrients or agrochemicals but rather enhance crop management. The types of biostimulants include non-microbials (seaweed extracts, humic substances, amino acids) and microbial biostimulants (beneficial bacteria and fungi). The choice of biostimulant depends on the specific needs of the crop and the desired outcome.
