Continuous limestone application can inhibit the copper (Cu) uptake by plants. This experiment was carried out in greenhouse conditions using two soils (Typic Oxisol and Typic Entisol) with different clay and soil organic matter (SOM) levels to evaluate the effects of liming on Cu fertilization. The treatments consisted of two dolomitic limestone rates (0 and 7.5 g per pot, equivalent to 0 and 5.0 Mg ha⁻¹) and five Cu rates (0, 2, 4, 8, and 16 mg kg⁻¹). Regardless of the soil type, the limestone and Cu rate interaction did not affect the grain yield (GY), however, they did increase the productivity, shoot dry weight yield (SDWY), number of grains per pod, number of pods per pot, pod weight per pot, weight of 100 seeds, root volume, photosynthetic rate, and chlorophyll, and Ca, Mg, and Cu contents in the soil and leaves. It was concluded that for soybeans cultivated in Typic Entisol and Typic Oxisol, there was no association between 5.0 Mg ha⁻¹ of limestone and the Cu rates. However, in isolation, limestone and Cu rate caused a significant increase in the soybean productivity, physiological components, and yield characteristics.

连续施用石灰石可以抑制植物对铜（Cu）的吸收。该实验是在温室条件下使用两种土壤（典型的Oxisol和Typic Entisol）具有不同的粘土和土壤有机质（SOM）水平进行的，以评估石灰对Cu施肥的影响。处理包括两种白云岩灰岩用量（每盆0和7.5克，相当于0和5.0 Mg ha ^-1）和五种铜用量（0、2、4、8和16 mg kg ^-1））。不论土壤类型如何，石灰石和铜的交互作用都不会影响谷物的产量（GY），但是，它们的确提高了生产率，枝干重量产量（SDWY），每荚的谷物数量，每盆的荚数量，每盆豆荚重量，100颗种子的重量，根体积，光合速率和叶绿素以及土壤和叶片中的Ca，Mg和Cu含量。结论是，对于在典型的Entisol和Typic Oxisol中种植的大豆，石灰石的5.0 Mg ha ^-1与Cu的含量之间没有关联。然而，孤立地看，石灰石和铜的添加量导致大豆产量，生理成分和产量特性的显着提高。
