采集响水县耕地0~20 cm土壤样本5366个，分析土壤有机质、全氮、有效磷、速效钾、pH值、可溶性盐分。结果表明：响水县土壤有机质含量偏低且分布不均，平均含量为15.2 g/kg；土壤全氮含量较高，平均值为0.92 g/kg；土壤有效磷含量较高，平均值为14.0 mg/kg；土壤速效钾含量较高且分布不均匀，平均值为98 mg/kg；土壤可溶性盐分含量明显降低，平均值为0.43 g/kg；土壤pH值平均为8.10，属碱性土壤；施肥结构存在问题。结合响水县的作物种植种类、土壤类型及土壤养分状况提出与之相应的施肥建议。
採集響水縣耕地0~20 cm土壤樣本5366箇，分析土壤有機質、全氮、有效燐、速效鉀、pH值、可溶性鹽分。結果錶明：響水縣土壤有機質含量偏低且分佈不均，平均含量為15.2 g/kg；土壤全氮含量較高，平均值為0.92 g/kg；土壤有效燐含量較高，平均值為14.0 mg/kg；土壤速效鉀含量較高且分佈不均勻，平均值為98 mg/kg；土壤可溶性鹽分含量明顯降低，平均值為0.43 g/kg；土壤pH值平均為8.10，屬堿性土壤；施肥結構存在問題。結閤響水縣的作物種植種類、土壤類型及土壤養分狀況提齣與之相應的施肥建議。
