In this study, the effects of various agro-industrial wastes were investigated when applied to soil alone or in combination with chemical fertilizers, regarding the risks of boron and heavy metal pollution of soils and plants. Nine combinations of production residues from various agro-industries, urban wastes, and mineral fertilizers were applied to potatoes in a field experiment. The content of available boron in the soil differed significantly (p < 0.05) among the applications. Generally, B values were found to be slightly higher when soapstock, prina, and blood were used alone or in combination. Although total Co, Cd, and Pb contents of soils showed no significant differences between the applications, Cr content differed significantly (p < 0.05). No pollution risk was observed in soil in respect to total Co, Cd, Pb, and Cr contents. The amount of boron and heavy metals in leaves showed no significant differences among the applications. Cobalt, Cd, and Pb in leaves were at normal levels whereas Cr was slightly above normal but well under the critical level. Boron was low in tubers and varied significantly between applications such as Co and Cd. The Co content of tubers was high, Cd and Cr contents were below average, and Pb content was between the given values. Some significant correlations were found between soil characteristics and the boron and heavy metal content of soil, leaves, and tubers.
在这项研究中，研究了在单独施用或与化肥结合施用各种农业工业废物时，硼和重金属对土壤和植物污染的风险。在田间试验中，将来自各种农业工业、城市废物和矿物肥料的九种生产残渣组合应用于马铃薯。土壤中有效硼的含量在应用之间存在显著差异（p<0.05）。一般来说，当单独使用或组合使用皂脚、prina 和血液时，B 值略高。尽管土壤中总 Co、Cd 和 Pb 含量在应用之间没有显著差异，但 Cr 含量存在显著差异（p<0.05）。就总 Co、Cd、Pb 和 Cr 含量而言，土壤中没有观察到污染风险。叶片中的硼和重金属含量在应用之间没有显著差异。叶片中的 Co、Cd 和 Pb 处于正常水平，而 Cr 略高于正常水平，但远低于临界水平。块茎中的硼含量较低，在 Co 和 Cd 等方面应用之间存在显著差异。块茎的 Co 含量较高，Cd 和 Cr 含量低于平均值，Pb 含量在给定值之间。土壤特性与土壤、叶片和块茎中硼和重金属含量之间存在一些显著相关性。
