Phosphorus (P) is a critical nutrient for crop growth, but its availability in soil is often limited, posing a challenge to agricultural productivity. This study focuses on the role of secondary metabolites in improving phosphorus efficiency in maize under low-phosphorus conditions. We examined metabolites from key metabolic pathways, including those involved in carotenoid biosynthesis, phenolic metabolism, and aromatic amino acid derivatives, for their potential to enhance phosphorus uptake and utilization. The results suggest that these metabolites can modulate various physiological processes, including root development and stress tolerance, which are essential for improving phosphorus efficiency in crops. Specifically, metabolites from the carotenoid and shikimic acid pathways have shown promising effects in boosting root biomass and improving phosphorus allocation within plants, while phenolic compounds demonstrated less significant impacts. Furthermore, the application of these metabolites appears to enhance the plant's ability to adapt to phosphorus scarcity by optimizing phosphorus uptake and improving overall plant growth and photosynthetic efficiency. These findings highlight the potential of secondary metabolites as biostimulants to enhance phosphorus efficiency, providing valuable insights for the development of sustainable agricultural practices and advanced biostimulant products.

Moreover, the demand for sustainable agricultural practices grows based on the latest EU CAP. This leads to the urgent need for traceable, transparent, and verifiable information about biostimulants. Digital Product Passports (DPPs), which are based in blockchain technology, are applied in a variety of industries, including agriculture. This work presents a conceptual framework for applying blockchain-based DPPs to the biostimulant sector, aiming to enable traceability from the raw materials and microbial strains to the field application.The current work proposes a DPP infrastructure that contains product origin, formulation and batch-level data, quality control parameters and field application records. Blockchain technology ensures decentralized verification, secure access data for all stakeholders as well as traceability and integrity.The pipeline designed emphasizes interoperability with existing agritech systems and the ability to support lifecycle assessments (LCA) and sustainability labeling. Also DPPs can be used for counterfeit prevention and compliance reporting.This proposed framework provides a roadmap for future development by applying DPPs, supply chain information and blockchain-based smart contracts. This approach can significantly improve the trust, efficiency, and sustainability of biostimulant use in modern agriculture.
