With increasing concerns about the environmental impact of fertilizers, there is a growing need for the sector to develop more sustainable, 'climate-smart' methods of crop production. Biostimulants have attracted growing attention since they offer the potential to enhance yields through stimulating natural processes in crops.

Biostimulants for sustainable crop production provides a comprehensive review of the key advances in understanding and using biostimulants. This collection covers the major groups of biostimulants, from humic substances and seaweed extracts to protein hydrolysates and plant growth-promoting rhizobacteria (PGPR), as well as the practical application of biostimulants in areas such as enhancing nutrient use efficiency (NUE).
