The "Corn N Rate Calculator" application is an essential tool for farmers and agricultural producers aiming to optimize their nitrogen (N) application strategies for maximum profitability. By inputting specific details about their fields, such as nitrogen and corn prices, producers can find the recommended N rate tailored to their unique conditions.

This app is designed to assist in selecting an optimal nitrogen rate that enhances profitability, even when nitrogen and corn prices fluctuate. The core feature of the application is the calculation of the Maximum Return to N (MRTN), which represents the nitrogen rate that will yield the highest profit for a given ratio of nitrogen to corn prices. The MRTN rate is displayed prominently on the screen as a large number in units of pounds per acre (lbs N/acre). This figure serves as the total nitrogen recommendation for the entire field. However, it's important to note that this number should be adjusted by subtracting the pounds of nitrogen per acre applied as starter fertilizer and any nitrogen credits received from previous applications.

Below the main MRTN value, the app provides a range of nitrogen rates that are also likely to result in profitable yields, staying within $1 per acre of the MRTN rate. This range offers flexibility and helps producers make informed decisions based on their specific circumstances and preferences.
