| ABSTRACT |
| Investigations were carried out on the micronutrient contents of major citrus orchard soils (involving seven soil great groups in 8 provinces and an autonomous region of southern China), and an evaluation on the abundance and deficiency of available micronutrients in these soils was made in this paper.In southern China, citrus orchard soils derived from sandstone, sandy shale, Quaternary red clay, diluvial deposit, granite gneiss and neritic deposit were deficient in available Mo and B and low in Zn. Those developed on purple sandy shale, limestone and slope deposit were all in short supply of available Zn, B and Mo. Coastal solonchak was fairly abundant in B, but its available Fe, Zn and Mo contents were rather low. |
