Li Q.; Tian Y.; Zhang X.; Xu X.; Wang H.; Kuzyakov Y. (2017)

© 2017 Elsevier B.V.Inputs of labile carbon (C) and nitrogen (N) affect the intensity and direction of priming effects (i.e., increase or decrease of soil organic matter (SOM) decomposition caused by labile inputs). Increased ...
Land use change decreases soil carbon stocks in Tibetan grasslands

Qiao N.; Xu X.; Cao G.; Ouyang H.; Kuzyakov Y. (2015)

© 2015, Springer International Publishing Switzerland. Backgrounds and aims: Land use is an important factor affecting soil organic carbon (SOC) dynamics and can produce positive C climate feedback, but its effects remain ...
Nitrogen acquisition by plants and microorganisms in a temperate grassland

Liu Q.; Qiao N.; Xu X.; Xin X.; Han J.; Tian Y.; Ouyang H.; Kuzyakov Y. (2016)
