| Abstract: | We investigated the availability of soil micronutrients, Cu, Zn, B, Mo, Mn and Fe, in the hilly area of North Hunan province. It was found that most of the soils in this area are lacking of Zn and B and some soils are poor in Cu and Mo. However, the soils are rich in Mn. Availability of the micronutrients depends closely on the parent materials. Soil pH and organic matter are also important factors influencing the availability of the micronutrients. |
