To evaluate partitioning and mutualistic interactions between wheat and soil microorganisms under warming, we investigated 15N redistribution between wheat and soil microorganisms and soil gross N transformation. The results show that conservation agriculture management alleviated N competition between wheat and soil microorganisms and favored plant nitrate acquisition by accelerating soil internal N transformations through changes in root metabolites quality compared to conventional agriculture under warming. The red arrow indicates increased microbial-mediated N processes following warming, and the blue arrow indicates reduced processes. The green and yellow lines represent N partitioning between plants and microorganisms and gross N transformation rates in conventional and conservation agriculture, respectively. GMR gross N mineralization rate, GNR gross N nitrification rate, GIR gross N immobilization rate. Some elements of this figure were created in BioRender. Cunkang, H.
