Abstract

[Objective] To explore the effect of vermicompost on soil organic carbon oxidation stability and carbon pool management index in cherry plantation(Cerasus pseudocerasus)

in order to provide scientific basis for improving soil quality management and the increase of agriculture carbon emission reduction potential. [Methods] A field experiment was conducted to determine the five treatments

CK(neither urea nor vermicompost was applied)

N100(100% of nitrogen was provided by urea)

M10N90(10% and 90% of nitrogen was provided by vermicompost and urea

respectively)

M30N70(30% and 70% of nitrogen was provided by vermicompost and urea

respectively)

and M50N50(50% and 50% of nitrogen was provided by vermicompost and urea

respectively) on soil organic carbon(SOC)

microbial biomass carbon(MBC)

readily oxidizable carbon(ROC) contents

organic carbon oxidation stability

as well as carbon pool management index(CPMI) of Cerasus pseudocerasus. [Results] The SOC contents under M30N70 and M50N50 treatments increased by 12.07% and 18.75% in comparison with the N100 treatment

respectively. The MBC and ROC contents and CPMI achieved the highest value in M30N70 treatment and had significant differences with other treatments

showing 51.34%

15.16% and 6.47% increases in ROC content and 73.07

30.06 and 20.71 increases in CPMI

respectively

compared to the treatments of N100

M10N90 and M50N50. However

the oxidation stability index of organic carbon in M30N70 treatment was obviously lower than other treatments

which decreased by 36.22% compared with N100 treatment. [Conclusion] In the cherry cultivation

application of vermicompost co-applied with inorganic fertilizer

especially the M30N70 treatment

was beneficial on soil quality amelioration and soil fertility improvement.
