pH value,organic matter content and available nutrients contents of 30 purple soil samples from Panxi tobacco-growing areas of Sichuan were determined.The results showed that the range of pH value in purple soil was from 5.13 to 8.14 in Panxi tobacco-growing areas,and about half of the soil samples were slightly alkali.With the pH value increasing,the contents of organic matter,hydrolytic N,available Zn and available Mn decreased,the contents of exchangeable Ca increased.But pH value had no significant correlation with available P,available K,exchangeable Mg,available Cu and available B.The purple soil had low content of organic matter and hydrolytic N,medium content of available P and available K,and was rich in exchangeable Ca and exchangeable Mg.Some soil with high pH value could be short of available Cu and available Zn.The content of available B was very low in different pH value of purple soil,and it was suggested to add B for balanced fertilization in tobacco production.
