The N-Tester BT is an innovative tool that helps farmers easily determine the nitrogen needs of their crops directly in the field. By accurately measuring the plant's nutritional status, the N-Tester BT helps fine-tune nitrogen fertilization, improving yield, grain quality, and profitability while minimizing environmental impact.

Why Nitrogen Matters: Nitrogen requirements for plants vary widely by field and year. By using the N-Tester BT, you can optimize the amount of nitrogen applied based on your crops’ real-time needs. This ensures the best possible results for your fields every season.

How It Works: The N-Tester BT measures the chlorophyll content of a plant's leaf, which reflects its nitrogen status. For the best results, readings should be taken from the middle of the youngest, fully developed leaf. After gathering 30 random measurements in a "W" pattern across the field, the N-Tester BT calculates an average value that informs how much nitrogen the crop requires.

Calibration and Recommendations: The N-Tester BT’s measurements are affected by crop variety and growth stage, which is why proper calibration is essential. Yara provides calibrations and expert agronomic support to ensure you get the best nitrogen recommendations for your crops.

By using the N-Tester BT, you can make precise, data-driven fertilization decisions that support better crop outcomes and increased profitability.
