1. Precision Fertilizer Management Enabled by Printed Sensors for Direct Soil Nitrate Monitoring

Modern farming relies on intensive fertilizer applications to ensure the plant production. However, a key challenge in fertilizer management, particularly nitrogen, is achieving a balance between maximizing crop yields and pursuing environmental stewardship. Uniform fertilizer applications often result in inefficiencies. Some areas receive insufficient fertilizer, resulting in reduced crop yields and caused financial losses. In contrast, other areas receive excessive amounts, leading to surplus... K. Chen, J. Andrews
