Abstract: n order to improve soil fertility of the newly reclaimed light sierozem in Ili,Xinjiang,five different fertilizing measures were taken and compared during a 3-year period.The fuzzy method was used as an integrated evaluation to calculate the values of integrated fertility index [WTBX](IFI).[WTBZ] The values of fertility index,IFI and crop yield under different fertilizing measures were compared.The results showed that soil fertility could be improved by applying organic fertilizer,especially by applying furfural residue,and soil pH value and soil volume weight could be reduced.The assessed results revealed that the value of IFI was the highest (0.826) when nitrogenous fertilizer,phosphatic fertilizer and potash fertilizer were applied with furfural residue,which revealed that this fertilizing measure was optimal to improve soil fertility.Application of organic material is an effective way of improving soil fertility,but the release of nutritive substance from organic material is relative slow.
