By characterizing the microbial communities in different sugarcane tissues, researchers have identified key bacterial families and genera that contribute to SNF and stress resilience (Singh et al., 2022). These insights enable the development of targeted microbial inoculants and the optimization of microbial consortia for enhanced SNF and crop productivity (Luo et al., 2023).

Studies have revealed the diversity and functional potential of endophytic and rhizospheric diazotrophs in sugarcane, highlighting their role in nitrogen fixation and plant growth promotion (Singh et al., 2022; Luo et al., 2023). By characterizing the microbial communities in different sugarcane tissues, researchers have identified key bacterial families and genera that contribute to SNF and stress resilience (Singh et al., 2022). These insights enable the development of targeted microbial inoculants and the optimization of microbial consortia for enhanced SNF and crop productivity (Luo et al., 2023). 5 Case Study 5.1 Detailed examination of a successful implementation of symbiotic nitrogen fixation in sugarcane production The case study by Martins et al. (2020) provides a comprehensive analysis of the successful implementation of symbiotic nitrogen fixation (SNF) in sugarcane production. This study highlights the potential of SNF to enhance sugarcane yield, improve soil health, and offer economic benefits by reducing the dependency on synthetic nitrogen fertilizers.
