Advancements in Precision Fertilization and Water Management for Sustainable Agriculture

Dear Colleagues,

The efficient utilization of water and fertilizers is crucial for achieving sustainable agricultural production. Integrated water–fertilizer management technologies and innovative irrigation–fertilization strategies are key to optimizing crop yield and enhancing resource use efficiency. Understanding the physiological and biochemical mechanisms that contribute to high yield and efficiency under various water and fertilizer management regimes is essential for developing advanced agronomic practices. Recent developments in precision agriculture, smart irrigation systems, and data-driven fertilization techniques offer valuable opportunities to improve water and nutrient use while mitigating environmental impacts.

This Special Issue focuses on the most recent research in crop water–fertilizer efficiency, integrated water–fertilizer management, and cutting-edge irrigation and fertilization technologies. We invite contributions that address the following areas:

• Mechanisms of High Yield and Efficiency: Investigating how crops respond physiologically, biochemically, and structurally to different water and fertilizer regimes to achieve optimal productivity.
• Integrated Water–Fertilizer Management: Strategies to harmonize water and nutrient use to enhance crop performance while conserving resources.
• Innovative Irrigation and Fertilization Technologies: The development and application of precision fertigation systems, controlled-release fertilizers, and smart irrigation technologies to improve water and nutrient use efficiency.
• Covering Technologies: Exploring the role of covering techniques such as plastic film mulching, straw mulching, and others to improve water and nutrient use efficiency and enhance crop productivity.
• Remote Sensing and Precision Agriculture: Utilizing UAVs, spectral imaging, and soil moisture sensors to monitor and optimize water and nutrient management in real time.
• Environmental and Economic Impacts: Assessing the sustainability of advanced water–fertilizer management techniques, focusing on nutrient loss reduction, soil health, and cost-effectiveness.

This Special Issue provides insights into innovative strategies for improving crop water and fertilizer efficiency, contributing to sustainable agricultural intensification. Future research should aim to develop affordable and scalable technologies, decision-support systems for smallholder farmers, and adaptive irrigation–fertilization models suited to diverse agroecosystems. Bridging the gap between research and field applications is essential to ensure the long-term sustainability and resilience of global agriculture.

We invite researchers and practitioners to submit their latest findings as part of this Special Issue. By advancing precision water–fertilizer management, we can enhance food security, optimize resource use, and reduce environmental footprints, ultimately paving the way for more sustainable agricultural practices.
