Dataset Information


Experimental supporting data on seasonal dynamics of different soil nitrogen pools affected by long-term fertilization regimes.

ABSTRACT: The data presented in this article are related to the research paper entitled "Changes in N supply pathways under different long-term fertilization regimes in Northeast China" [1]. Seasonal dynamics of soil NH4 +-N, NO3 --N, soil microbial biomass nitrogen (N) and fixed NH4 + were provided on the basis of a 26-year long-term experiment, including six treatments: no fertilizer (CK), recycled manure (M), N and P fertilizers (NP), P and K fertilizers (PK), N, P and K fertilizers (NPK), and NPK fertilizers with recycled manure (NPKM). The presentation of potential N retention and supply through soil microbial biomass N and fixed NH4 + pools at different growth stages is helpful for comparing the effects of different N pools on soil N transformation and assessing synchronies between crop N demand and soil N supply through different N pools.
