“…DNA-based methods have been utilized to analyze the nitrifier communities and abundance, along with potential nitrification assays to assess BNI in the field (Burnham et al, 2022). However, DNA-based methods have limitations in accurately reflecting in situ nitrification rates (Nardi et al, 2022), and the exact microbial groups that contribute to the nitrification function can be masked. To approach true field rates, measurements such as DNA stable isotope probing and RNA-based methods such as metatranscriptomics, are suggested (Blanc-Betes et al, 2023;Yang et al, 2022).…”

Perennial tall grasses show promise as bioenergy crops due to high productivity and efficient nutrient use. Ongoing research on bioenergy grasses seeks to reduce their reliance on synthetic nitrogen (N) fertilizer, the manufacture of which relies on fossil fuel combustion. Excessive use of fertilizers also causes adverse environmental consequences and leads to the evolutionary loss of plant traits beneficial to sustainable N cycle. Notably, perennial tall grasses have exhibited the potential to maintain high biomass yield without the need for N fertilizer or causing soil N depletion. Perennial grasses can be adept at interacting with their microbial partners to facilitate N acquisition and retention via mechanisms such as biological N fixation and nitrification inhibition. These inherent N management traits should be preserved and optimized at the this early stage of bioenergy grass breeding programs. This review examines the impact of external N on bioenergy grass production and explores the potential of leveraging advantageous N‐cycling attributes of perennial tall grasses, laying groundwork for future management and research efforts. With minimized dependency on external N input, the cultivation of perennial energy grasses will pave the way toward more resilient agricultural systems and play a significant role in addressing key global energy and environmental challenges.
