对湛江地区辣椒地土壤取样，测定了容重pH、及有机质、全氮、碱解氮、速效磷、速效钾含量。结果表明，辣椒地土壤肥力比甘蔗地土壤有明显改善，且随年限延长呈提高的趋势；与甘蔗地土壤比较，辣椒地土壤速效钾含量呈降低趋势。
Soil samples from pepper field in Zhanjiang were taken for determination of bulk density, pH, organic matter, total nitrogen, available nitrogen, available phosphorus and available potassium. The results showed that the soil fertility of pepper was significantly improved compared with the soil of sugarcane and increased with the extension of years. Compared with the soil of sugarcane, the content of available potassium in soil decreased.
