Description
Extra nitrogen reaches grassland soil in two ways: legume plants fix it from the air, and polluted rain drops it from above. Xin Liu and co-authors compared the two in karst grasslands of southwest China. For five years they planted a legume in some plots, spread nitrogen fertilizer in others, and left the rest alone. Then they read the soil microbe mix from fatty acid markers.
The two nitrogen sources pulled the microbe community in different directions. Deposited nitrogen shrank bacteria, actinobacteria, and helpful root fungi. The legume slightly grew every group instead. Total microbe mass and fungal mass ended higher under legumes. The authors favor planting legumes to keep karst soils alive and stable.
