Whether wheat can achieve high and stable yields largely depends on the management of nutrients in the soil. Integrated Nutrient Management (INM) can increase wheat yield and better protect the soil environment. A reasonable combination of organic fertilizer, chemical fertilizer and bio-fertilizer can significantly increase the grain yield and protein content of wheat. Compared with the single application of chemical fertilizers, INM is more effective in reducing the amount of chemical fertilizers used and can also lower the risk of nutrient loss. The research explored various precise nutrient management measures. It is necessary to promote the integration of INM and climate-smart agriculture to meet the wheat production demands of different regions and provide a reference for optimizing the nutrient management model of wheat. Keywords Wheat (Triticum aestivum L); Integrated Nutrient Management; Nutrient Use Efficiency; Soil Health; Sustainable Agriculture 1 Introduction Approximately 40% of the population takes wheat as their main staple food. Wheat grains can provide an energy source for humans and livestock, and are also an important source of protein and mineral elements (Hassouni et al., 2025). The gluten protein contained in wheat has good extensibility and viscosity, which makes it very suitable for processing into noodles and a variety of foods. In agricultural production, if only chemical fertilizers are used for a long time, it is easy to bring about a series of problems. The organic matter in the soil will continuously decrease, some macronutrients and micronutrients will gradually be deficient, the soil structure will also be damaged, and the biological activity in the soil will significantly decline (Sharma et al., 2020; Kumar et al., 2022). In irrigated wheat cultivation and long-term crop rotation systems, the fertilization methods are often dominated by nitrogen, phosphorus and potassium, but the input of organic fertilizers and the supplementation of medium and trace elements are also easily overlooked. Integrated Nutrient Management (INM) uses chemical fertilizer together with manure, compost, crop residues, green manure, and helpful soil microbes. In wheat systems, including wheat grown with rice, maize, or peanuts, INM can raise grain yield and nutrient uptake (Sharma et al., 2019). This study reviews the main scientific and practical challenges of nutrient management for wheat as a global staple food, comprehensively analyzes the impacts of INM on wheat yield, quality, nutrient use efficiency, soil health, and economic benefits, as well as its environmental effects, and proposes future research and technology integration directions oriented towards regional differences and climate change scenarios. This provides a theoretical basis and practical reference for developing sustainable wheat nutrient management strategies adapted to different ecological zones and production types. 2 Nutrient Requirements and Absorption Characteristics of Wheat 2.1 Major macroelements (N, P, K) and their physiological functions In wheat production, the rational combination and application of nitrogen, phosphorus and potassium nutrients can enhance dry matter accumulation and nutrient absorption. In the treatment of applying 125 kg N·ha-1 in combination with 50 kg K2O·ha-1, the wheat yield could reach 6.3 t/ha. At this time, the contents of nitrogen, phosphorus and potassium in the grains were approximately 15.5, 3.6 and 5.8 g/kg respectively (Rawal et al.,
