Journal ArticleDOI
Linking absorptive roots and their functional traits with rhizosphere priming of tree species
TL;DR: It is found that the RPE of Chinese fir across the three soils decreased with an increase in soil C/N ratio, which conflicted with the N mining hypothesis and suggests that soil C stabilization mechanisms associated with clay minerals may play an important role.
Journal ArticleDOI
Rhizosphere-mediated effects of the invasive grass Bromus tectorum L. and native Elymus elymoides on nitrogen cycling in Great Basin Desert soils
TL;DR: A greenhouse study to isolate rhizosphere effects on N cycling by the invasive annual grass Bromus tectorum L., and the native perennial grass, Elymus elymoides (Raf.) Swezey, in invaded and uninvaded soils found a negative effect on soil N availability via root-mediated processes, even though its growth and competitiveness increased in invaded soils.
Journal ArticleDOI
Plant inputs mediate the linkage between soil carbon and net nitrogen mineralization.
TL;DR: Investigation of the influences of long-term deprivation of plant inputs, short-term addition of maize straw and experimental warming on soil C and net N mineralization and their relationships provides evidence that plant inputs mediate the relationships between soil B and C, and is thus critical in controlling ecosystem C and N cycling.
Journal ArticleDOI
Aridity thresholds of soil microbial metabolic indices along a 3,200 km transect across arid and semi-arid regions in Northern China
Jianfeng Hou,Feike A. Dijkstra,Xiuwei Zhang,Xiuwei Zhang,Chao Wang,Xiao-Tao Lü,Peng Wang,Xingguo Han,Weixin Cheng,Weixin Cheng +9 more
TL;DR: Investigation of soil microbial metabolic indices and the degree of carbon limitation for microbial respiration along a 3,200 km transect with a wide aridity gradient implies that microbial metabolism is distinctively different in arid lands than in non-arid lands.
Journal ArticleDOI
Soil micro-food web interactions and rhizosphere priming effect
Xinchang Kou,Xinchang Kou,Tongqing Su,Tongqing Su,Ningning Ma,Qi Li,Peng Wang,Zhengfang Wu,Zhengfang Wu,Wenju Liang,Weixin Cheng,Weixin Cheng +11 more
TL;DR: This connection indicates that soil micro-food web interactions in the rhizosphere may either regulate microbial turnover and/or microbial community composition, subsequently modulating the RPE.
