Farmers unable to optimize nitrogen fertilizer application, wasting money on excessive inputs during high-price periods

Corn and grain farmers face skyrocketing fertilizer costs but lack practical methods to measure and optimize nitrogen use efficiency in real-time. Current farming practices rely on generic application rates rather than field-specific data, causing farmers to overapply expensive fertilizer or underapply and reduce yields. Existing soil testing and tissue sampling methods are time-consuming, delayed, and don't provide actionable insights fast enough to adjust mid-season applications.
