Abstract:
The severely eroded granitic red soil were improved on four different patterns in Changting County, Fujian, and the soil chemistry, soil microbes, soil enzymes and soil respiration over different patterns were studied in 1992. The results showed that the amounts of soil bacteria, fungi, actinomyces and total microbes were increased obviously, the soil hydrolytic and oxidation-rcduction cnzymcs and soil rcspiration were enhanced evidently, the storage of soil nutrients and supplying intensities of various available nutrients were promoted pronouncedly, demonstrating that the fertility of the soil improved on all the patterns was restored to varying degrees. Therefore, proper biological measures and essential supplementary engmeenng measures are effective in improving the fertility of severely degraded red soil.
