This study investigates how long-term phosphorus fertilization affects microbial carbon use efficiency and soil organic matter decomposition in non-allophanic Andosols, finding that P levels influence priming effects and CUE.

This study shows that soil pH, shaped by long-term fertilizer application, is the main driver of nitrogen cycling gene abundances in acidic grasslands, more so than direct fertilizer effects.

The paper compares taxonomic and functional microbial diversity in farmlands and natural lands across scales in Kenya and Malawi, finding broader functional homogenization due to farming.

This study shows that long-term liming increases microbial nitrogen-cycling gene abundance and stabilizes their populations against seasonal changes without increasing nitrous oxide emissions.

This paper reports a field survey in Kabwe, Zambia, assessing lead contamination through plant communities, spectral imaging, and soil/water Pb levels.
