Effect of Different Proportinons of Chicken Manure Co-applied with Inorganic Fertilizer on Poplar Seedings Groth and Soil Organic Carbon
A pot experiment was conducted to study the influence of different fertilization treatments on soil organic carbon(SOC)
active organic carbon(AOC) and carbon pool management index(CPMI). The experiment included five treatments: CK(neither urea nor chicken manure was applied)
N100(100% of nitrogen was provided by urea)
M10N90(10% and 90% of nitrogen was provided by chicken manure and urea
respectively)
M30N70(30% and 70% of nitrogen was provided by chicken manure and urea
respectively)
and M50N50(50% and 50% of nitrogen was provided by chicken manure and urea
respectively). The results showed that the SOC contents under M30N70 and M50N50 treatments increased by 8.11% and 14.64% in comparison with the N100 treatment
respectively. The AOC content and CPMI achieved the highest value under M30N70 treatment and had significant differences with other treatments
showing 47.36%
14.93% and 7.14% increases in AOC content and 65.49
26.74 and 20.22 increases in CPMI
respectively
compared to the treatments of N100
M10N90 and M50N50. At the same time
M30N70 treatment had the maximum increase in the growth of poplar seedlings. The content of soil AOC was significantly positively correlated with the content of SOC
ground diameter and height of poplar seedlings
while was extremely significantly positively correlated with CPMI. Furthermore
the CPMI had significantly positive correlation with ground diameter and height of poplar seedlings
which would be a good index to assess influence of fertilization practice on soil quality. In conclusion
the different proportions of chicken manure co-applied with inorganic fertilizer had a significant influence on organic carbon
active organic carbon
CPMI and the growth of poplar seedlings
especially M30N70 treatment
which achieved the best effects among all the treatments and was the best proportion of chicken manure and inorganic fertilizer.
