Cornell Scientists Engineer Tomatoes That Turn Red-Purple When Nitrogen Is Low

<b>Cornell University</b> scientists have successfully engineered a unique variety of tomatoes that visually change color to a striking red-purple when nitrogen levels in the soil are low. This genetic innovation aims to provide farmers with a direct visual indicator of crop nutrient needs.<br><br>The development addresses a major agricultural challenge by potentially reducing the overuse of synthetic fertilizers while maintaining optimal crop health and yields. Nitrogen deficiency often stunts plant growth, making early detection crucial for modern sustainable farming practices.<br><br>This breakthrough could soon help growers worldwide optimize fertilizer application and minimize environmental runoff.
