Active sensors are becoming an important tool in modern farming, especially for managing nitrogen use in crops like corn. In a recent episode of the Advancing Nitrogen Smart Podcast, experts Brad Carlson and Jeff Vetsch explain how this technology helps farmers make better decisions.
Active sensors are devices that collect real-time data from crops. These sensors measure crop health, growth, and color to understand how much nitrogen plants need. This helps farmers apply the right amount of fertilizer at the right time, which improves efficiency and reduces waste.
The Southern Research and Outreach Center have tested different sensor brands to understand their performance. Their research shows that these tools can be useful, but results may vary depending on field conditions and crop stage.
Experts explain that corn must reach a certain growth stage before sensors can provide accurate information. If used too early, the data may not be reliable. Farmers need to wait until the crop has enough growth for sensors to properly measure plant health.
Other field factors, such as soil texture and irrigation systems, also affect how well sensors work. In some cases, these factors may influence sensor readings, while in others, they may have limited impact. This means farmers must consider overall field conditions when using this technology.
Variable rate nitrogen technology allows farmers to apply different amounts of fertilizers across a field. This approach helps improve crop yield while reducing costs and environmental impact.
The podcast discussion is part one of a two-part series focused on nitrogen management. It also shares helpful resources, including tips for sensor-based nitrogen use and guidance on evaluating results.
Farmers are encouraged to explore these tools and learn how to use them effectively. By combining technology with proper knowledge, they can improve productivity and support sustainable farming practices.
