Abstract

[Objective]The research aimed to find out the soil nutrient status of corn growing areas in Xinping County,and guide scientific fertilization. [Method]Soil pH,organic matter,hydrolytic N,available P,available K,effective Mg,effective S,effective B,effective Mn and effective Zn were analyzed of tobacco growing areas in Xinping County. [Result]54. 48% soil was acidic. 35. 69% soil organic matter was lower.30. 68% hydrolytic N,36. 5% P,41. 81% K,35. 95% S,12. 42% Mg,84. 31% B,16. 99% Mn,56. 86% Zn were deficient. [Conclusion]Attention should be paid to the regulation of soil pH and the application of organic fertilizer and trace element fertilizer.
