Nitrogen fertilizer overuse in fields causes extreme damage to local river ecosystems and poses an environmental danger worldwide. Modulating and testing the exact amounts of fertilizer needed to grow crops can benefit these local ecosystems, optimize plant growth, and increase the overall knowledge about fertilizer use in the industry. Utilizing servos, valves, seven different types of sensors, a microcontroller, and a pump, this scale model project creates a scalable system that can be implemented in farms to deliver precise quantities of nitrogen, phosphorous and potassium for optimal plant growth.
