Effect of long-term application of inorganic fertilizer and organic amendments on soil organic matter and microbial biomass in three subtropical paddy soils



Effect of long-term application of inorganic fertilizer and organic amendments on soil organic matter and microbial biomass in three subtropical paddy soils



Nutrient Cycling in Agroecosystems 81(1): 17-24



Soil organic matter (SOM), microbial carbon (C-mic), and microbial nitrogen (N-mic) status affected by the application of inorganic fertilizer and organic amendments in subtropical paddy soils were investigated. Soil samples were collected from the plow layer of three long-term (17 years) field experiments at Xinhua, Ningxiang, and Taojiang counties in Hunan Province, China. Results showed that, compared to the control, application of inorganic fertilizer alone showed no significant effect on soil organic C (SOC), total N (N-tot), C-mic and N-mic. The application of inorganic fertilizer along with manure or straw significantly increased SOC and N-tot and soil C-mic and N-mic contents for all three sites, while following an application of inorganic fertilizer along with straw only for two sites. C-mic and N-mic were closely correlated with SOC and N-tot, respectively. In conclusion, application of inorganic fertilizer along with manure or straw is an effective way of enhancing SOM and microbial biomass in subtropical paddy soils.
