Different Cropping Patterns to Restore Saline-Alkali Soils in Northeast China Affect the Abundance of Functional Genes in the Soil Nitrogen Cycle

Abstract: Considerable attention has been paid to the establishment of an appropriate cropping patterns for the restoration of saline-alkali lands. This study’s goal was to explore changes in nitrogen-cycling (N-cycling) gene (nitrogen fixation: nifH; nitrification: AOA, AOB, and nxrB; denitrification: narG, norB, and nosZ) abundance of three cropping patterns at two soil depths in saline-alkali soils. Results showed that rotation and mixture promoted soil nutrients. N-cycling functional genes were significantly influen… Show more

“…Although the above microbial functional genes have been well-studied in several soil and environmental conditions (Philippot et al, 2013;Ding et al, 2023;Chen et al, 2021;), studies assessing the effect of overgrazing and grazing-exclusion on the microbial functional genes in soils from Caatinga tropical dry forest have yet to be reported. Here, we assessed the dynamics of amoA, nifH, nirK, nirS, nosZ, and phoD genes in soils under desertification (overgrazing) and restoration (grazing-exclusion) in the Brazilian semiarid region.…”
