Soil Fertility of Different Stands in the Taibai Mountains
The forest soil fertility in six different stands, Quercus aliena, Quercus baronii, Ulmus pumila,Ailanthus altissima, Quercus liaotungensis, and Koelreuteria paniculata in the Taibai Mountains were studied. The results showed that, different tree species had different effects on soil fertility. Contents of alkali-hydrolyzable N in the Q. aliena forest and the A. altissima forest were higher than other stands.The content of available P in U. pumila forest was far higher than others, which was 12.69 mg· kg-1 (0～20 cm soil layes). The organic matter (159.42 g · kg-1 )and the cation exchange capacity (51.54 cmol ·kg-1) of the A. altissima forest were the highest.
