调查分析位于广东省湛江农垦属下华海公司、南华农场、红星农场、丰收公司、广前公司、五一农场、湖光农场和友好农场等8个单位1918个土样的养分状况，与第二次土壤普查比较，对比集约化种植后砖红壤肥力变化。结果发现： pH呈下降趋势，即有土壤酸化特征；土壤有机质含量总体呈现较高水平，但也呈现下降趋势；土壤全氮总体仍处于中等偏上水平；土壤有效磷含量明显提高，总体处于良好水平；土壤速效钾含量有很大程度增加，但仍处于中等水平。

This paper an alyzes 1918 nutrient status of soil samples from Huahai Farm, Nanhua Farm, Dongfanghong Farm, Fengshou Company, Guangqian Company, Wuyi Farm, Youhao Farm, eight units which belongs to Zhanjiang agricultural reclamation of Guangdong. Compared with the second national soil survey, following is the changes compared to intensive cultivation of the lateritic soil fertility pH decreased, showing a feature of soil acidification;generally showed a high level in soil organic ingredients content accompany a downward trend; overall nitrogen is at least still in the middle level; phosphorus content in soil significantly improved overall to highlevel; meanwhile soil potassium has increased to a large extent, but still at a medium level.
