Causes and Countermeasures of Plantation Soil Available Phosphorus Deficiency in Southern China

The lack of available phosphorus in soil is an important reason that restricts the development of agroforestry in China,but there are few reports on the forest soil phosphorus deficiency and its countermeasures. In view of this, this paper reviews the characteristics of plantation soil phosphorus in southern China, discusses the reasons behind the deficiency of available phosphorus in the soil of plantation forests from a range of aspects, and analyzes the possible hazards that the phosphorus deficiency might cause to forests and trees. At the end, the current methods for coping with soil available phosphorus deficiency are summarized to provide references for the effective utilization of potential soil phosphorus in plantation forests and the maintenance of sustainable forest management.
