| Abstract: | The ASI method is a good method in evaluating the nutrient supplying properties in soils The soil nutrient status and nutrient limiting factors in three typical litchi plantations located in Zengcheng city Guangzhou,Boluo county in Huizhou,Gaozhou county in Maoming of Guangdong province,respecitively.The results of soil adsorption trial showed that the capability of soil to fix nutrients in these three spots decreased in the order P>K>B>S>Mn,Cu and Zn for Gaozhou Maoming,Mn>K>P>B>Cu>S and Zn for Boluo Huizhou,and K>B>S>Zn>P>Mn and Cu for Zengcheng Guangzhou.The pot experiment results indicated that the primary nutrient limiting factors in Gaozhou Maoming and Zhengcheng Guangzhou spot were N and P,that in Boluo Huizhou spot was N. |
