Analysis of soil nutrients of the newly-increased farmland in the process of land consolidation in Gaoling County.

【Objective】 More effective land consolidation is put forward by analyzing the characteristics of nutrient content of the newly-increased farmland soil in the process of land consolidation.【Method】 17 soil samples of the newly-increased farmland converted from industry land,tomb land,field land and bulrush land are collected in Tongyuan-Wanzi land consolidation project Gaoling County.The content of soil organic matter,total nitrogen,available P,available K and base-exchange capacity are measured and the characteristics of nutrient content are analyzed with the software of SPSS.【Result】 The results show that,the means of soil organic,matter total nitrogen,available P,available K and base-exchange capacity are 16.53 g/kg,4.72 g/kg,84.94 mg/kg,202.80 mg/kg and 13.25 cmol/kg.The change of nutrients in different newly-increased farmland is higher.The means of CV of soil organic,matter total nitrogen,available P,available K and base-exchange capacity are 80.49%,6.22%,31.77%,37.06% and 21.10%.The former land use patterns do not affect the change of nutrients in different newly-increased farmlands.The correlation between each nutrients is weak.The correlation coefficients of soil organic-available P and base-exchange capacity,available P-available K and base-exchange capacity are 0.415,-0.372,0.459 and 0.375.【Conclusion】 The means of soil nutrients in the newly-increased farmland reached a high level,which can meet agricultural requirements.While maintaining the balance of soil organic matter and improving soil organic matter content,more importance should be attached to the application of both organic and inorganic fertilizers.
