Next-Generation Nutrient Management Strategies for Wheat: Enhancing Productivity and Soil Quality

Abstract

Wheat (Triticum aestivum L.) is a staple food crop worldwide, but faces significant challenges including declining soil fertility, increasing fertilizer costs, and environmental concerns associated with conventional nutrient management practices. This review explores next-generation strategies for enhancing wheat productivity and soil quality through innovative nutrient management approaches. We discuss precision agriculture techniques, such as site-specific nutrient management and variable rate fertilization, which can improve nutrient use efficiency and reduce environmental impacts. The role of organic amendments, including compost, manure, and biochar, in improving soil health and nutrient availability is also examined. Additionally, we highlight the potential of plant growth-promoting rhizobacteria and mycorrhizal fungi to enhance nutrient uptake and plant growth. The integration of these complementary approaches offers promising pathways for sustainable wheat production systems that can meet growing global food demands while preserving ecosystem services. Future research should focus on developing region-specific nutrient management protocols and evaluating the long-term economic and environmental benefits of these innovative strategies.
