- W3141361296 abstract "A systematic study concerning the effects of a long term stationary fertilization on content and property of soil humus in Fluvo aquic soil sampled from Malan Farm, Xinji City, Hebei, and Arid red soil and Paddy red soil sampled from the Institute of Red Soil, Jinxian County, Jiangxi was conducted. The results showed that long term fertilization affected not only the content and composition of soil humus, but also the physico chemical property of the soil humus. With applying organic manure or applying both organic manure and chemical fertilizer, E 4 and E 6 values of humic acid decreased in the Fluvo aquic soil and the Arid red soil, but increased in the Paddy red soil. E 4 and E 6 values of humic acid increased with single application of chemical fertilizer. In the Paddy red soil but they changed a little in Fluvo aquic soil and Arid red soil. The effects of long term fertilization on the visible spectroscopic property of fulvic acid were different from that of humic acid. Long term application of organic manure or application of both organic manure and chemical fertilizer could increase E 4 and E 6 values of fulvic acid in all the three types of soil. Single application of chemical fertilizer had little effect on the E 4 and E 6. Long term fertilization could also influence the ultraviolet spectroscopic property of humus. With single application of organic manure or application of both organic manure and chemical fertilizer, the ultraviolet absorbance of humic acid and fulvic acid increased in all the three types of soil. But this effect was obvious only in short wave length and decreased as the wave length increased. With single application of chemical fertilizer the ultraviolet absorbance of fulvic acid increased in all the three types of soil, but that of humic acid increased only in Fluvo aquic soil. Long term application of organic manure or application of both organic manure and chemical fertilizer increased the contents of total acidic groups, carboxyl groups and phenolic hydroxyl groups of humic acid and fuvic acid in the three types of soil. Single application of chemical fertilizer had little effects on the content of total acidic groups, carboxyl groups and phenolic hydroxyl groups of humic acid and fuvic acid in the three types of soil." @default.
