Biostimulants present promising opportunities for sustainable agriculture by boosting crop growth, productivity, and resilience, whilst reducing reliance on traditional chemical inputs. They can enhance nutrient efficiency, support adaptation to climate change impacts, and contribute to environmentally resilient farming systems. Nevertheless, broad commercial and practical uptake remains constrained by critical barriers. These obstacles include irregular product performance, fragmented regulatory environments, inconsistent formulations, and limited understanding of the underlying biological mechanisms. Economic constraints also hinder their widespread use. Overcoming these hurdles requires coordinated progress across scientific research, regulatory policy, and agricultural practice. Addressing formulations, mechanistic insights, and performance consistency will be vital to unlocking the full agronomic benefits of biostimulants.
Modern farming must feed growing populations whilst reducing environmental damage from synthetic fertilisers and pesticides. Biostimulants offer natural methods to strengthen crops and improve nutrient uptake, helping farms adapt to changing climates. Clarifying how they function and establishing clear regulatory standards will help ensure these tools can be reliably adopted across the agricultural sector.
Biostimulants target agricultural producers seeking sustainable alternatives to synthetic inputs, but market readiness is held back by formulation variability, regulatory hurdles, and economic constraints. The work outlines pathways rather than testing a specific product, indicating an early- to intermediate-stage position where commercialisation depends on creating standardised formulations, clarifying biological mechanisms, and harmonising regulatory policies for commercial agricultural supply chains.

Biostimulants are emerging as pivotal tools in sustainable agriculture, offering innovative approaches to enhance plant growth, resilience, and productivity while mitigating the environmental impacts of conventional agricultural chemicals. However, their broader adoption faces significant challenges due to inconsistent formulations, fragmented regulatory frameworks, and limited understanding of their mechanisms of action. This review aims to address these research gaps by examining the historical development, diverse classifications, and complex mechanisms underlying biostimulants' efficacy. A major focus is placed on identifying and elaborating on the current challenges, including the variability in product performance, regulatory obstacles, and economic constraints. Furthermore, this review highlights the potential of biostimulants to improve nutrient efficiency, mitigate climate change impacts, and foster resilient agricultural systems. By emphasizing recent innovations and proposing a holistic framework for research, policy, and practical application, this review underscores the imperative of advancing biostimulant science to unlock its full potential in shaping the future of sustainable agriculture.
