Abstract: “BLOCKCHAIN-BASED SYSTEM AND METHOD FOR SECURE FERTILIZER AND AGRO-CHEMICAL DISTRIBUTION CONTROL” The present invention relates to an integrated blockchain-based system (100) and method (200) for secure and controlled distribution of fertilizers and agro-chemicals across a supply chain. The system (100) comprises a data acquisition module (110) including a microcontroller (10), soil moisture sensor (15), nutrient sensor (20), display module (25), alert module (30), and cloud interface (35) for real-time monitoring. A blockchain contract control unit (120) with a validation engine (40) executes smart contracts to verify user roles, fertilizer batch certification, purchase eligibility, and subsidy compliance. A distributed blockchain ledger (130) ensures immutable storage of certification and transaction data. A dashboard interface (140) facilitates quality verification, quota authorization, and transaction execution. The method (200) enables role-based access control, batch validation, misuse prevention, and traceability. The system ensures decentralized, transparent, and tamper-resistant management of fertilizer distribution without reliance on a centralized database. Refer: FIG. 1
