Soil microarthropods significantly influence nitrogen cycling in soil by affecting microbial activity, especially in nitrogen-limited environments.
Challenges in studying these tiny arthropods in natural settings have led researchers to use lab experiments, which limit understanding of their ecological roles in the field.
An open-field mesocosm setup revealed that the presence of abundant microarthropods increased ammonium and nitrate leaching in chernozem soil but showed less pronounced effects in sandy soil, highlighting the importance of soil type over nitrogen fertilization in determining their impact on nitrogen cycling.
