摘要
土壤的形成取决于母质的性质,而母质的性质必然会影响土壤的养分状况。本研究对尼日利亚奥贡州奥巴费米-奥沃德地方政府辖区埃韦科罗地层上覆水成岩土壤的性质和微量营养元素状况进行了评估。采用刚性网格调查法进行了详细的土壤调查,并根据已确定的绘图单元挖掘了三个剖面坑,按照粮农组织的指导方针进行了地理坐标定位、取样和描述。对收集到的数据进行了方差分析(ANOVA),通过邓肯多范围检验(DMRT)对平均值进行了分离,并使用皮尔逊相关系数来确定土壤特性之间的关系。根据研究结果,土壤颜色以灰褐色(10YR4/2)为主,结构为亚方形块状。容重为 1.65 g cm-3,土壤 pH 值为强酸性至微酸性(4.5-6.1),有机碳含量由低到高(6.1-21.9 g kg-1),全氮含量由低到高(0.3-6.3 g kg-1),可利用磷含量由低到中(0.34-13.40 mg kg-1),阳离子交换容量较低(1.74-4.18 cmol kg-1),碱饱和度较高(62.9-77.7%)。铁(20.49-270.29 毫克/千克-1)和锰(0.53-53.09 毫克/千克-1)均处于有毒水平,而铜(0.63-3.50 毫克/千克-1)和锌(0.51-10.36 毫克/千克-1)则处于中等水平。各土壤特性之间存在明显的正相关关系。总之,这些土壤的肥力处于中低水平,由于基质饱和度高,可以向植物释放养分。建议在耕作时将有机肥和农家肥掺入土壤中,以改善土壤物理状态,增加有机质含量,降低金属毒性。
Properties and micronutrients status of hydromorphic soils overlying Ewekoro formation in Ogun State, Nigeria
The formation of soil depends on the properties of the parent material which invariably affect its nutrient status. The properties and micronutrients status of hydromorphic soils overlying Ewekoro formations in Obafemi-Owode Local Government Area, Ogun State, Nigeria were evaluated. A detailed soil survey was carried out using the rigid grid survey and three profile pits were dug based on the identified mapping units, georeferenced, sampled, and described following FAO guidelines. Data collected were subjected to analysis of variance (ANOVA), means were separated by Duncan’s Multiple Range Test (DMRT), and Pearson’s Correlation Coefficients were used to determine relationships between soil properties. Based on the findings, the soil colour was dominated by greyish brown (10YR4/2) with sub-angular blocky structure. Bulk density was < 1.65 g cm−3, soil pH was strongly to slightly acid (4.5–6.1), low to high organic carbon (6.1–21.9 g kg−1), low to high total nitrogen (0.3–6.3 g kg−1), low to moderately available phosphorus (0.34–13.40 mg kg−1), low cation exchange capacity (1.74–4.18 cmol kg−1), and high base saturation (62.9–77.7%). Both iron (20.49-270.29 mg kg−1) and manganese (0.53–53.09 mg kg−1) occurred at toxic levels, while copper (0.63–3.50 mg kg−1) and zinc (0.51–10.36 mg kg−1) were at moderate levels. There were significant positive correlations among the soil properties. In conclusion, the soils had low to moderate fertility and can release nutrients to plants due to high base saturation. Incorporation of organic and farmyard manures into the soils during tillage to enhance soils physical status, increase organic matter levels, and reduce metal toxicity is recommended.
