摘  要:
Field experiments on the decomposition of organic materials andthe accumulatoin of organic carbon in infertile red soils wereconducted at the Ecological Experimental Station of Red Soil, theChinese Academy of Sciences, and the potential of CO_2 sequestrationby rechlamation and improving the fertility of these soils wasestimated. Results showed that in infertile red soils, thehumification coefficients of organic materials were rather high,ranging from 0.28 to 0.63 with an average of 0.43, which was 41/100higher than tjhose in corresponding red soils with medium fertility.
