Fertilizer Quality Testing Machine Using NPK

This abstract outlines a new machine for testing fertilizer quality that utilizes NPK analysis to measure nutrient levels in different types of fertilizers, including granular, powdered, and liquid forms. The device uses chemical reagents and optical sensors to measure the amounts of N,P, and K in the fertiliser samples and calculate those levels. The system produces quick, automated results that are simple to read and can be exported for more research. This technology is expected to improve the quality control of fertilizers, ensuring that farmers can access high-quality fertilizers that meet their specific nutrient requirements.
