This study assessed in situ stabilization combined with phytoexclusion in practical application on agricultural land contaminated strongly, and spatially heterogeneous, with metals (Cd, Pb, and Zn) and As. Single and combined lime marl and phosphate treatments were consecutively planted with two cultivars each of rape, wheat, and barley differing in trace elements (TE) accumulation. The effects on soil acidity, NH₄NO₃-soluble, and straw and grain TE concentrations were evaluated. The combined fertilizer treatment most effectively reduced metals mobility, but neither amendment mitigated plant TE status, which correlated more with pseudo-total than NH₄NO₃-soluble TE in soil. The cultivar choice reduced grain Cd by 39 or 21% in barley or wheat, respectively, simultaneously decreased grain Zn, but conversely affected As uptake in wheat grains. The lack of correlations between grain TE concentrations suggests the potential for breeding cultivars with low Cd and As accumulation without causing Zn malnutrition. The cereals had relatively low yields, particularly on highly polluted areas, and only rape and barley grains unexceptionally suited for animal consumption. Agricultural measures and climatic conditions influenced TE mobility. The cultivars’ TE uptake varied less than in greenhouse studies, stressing the importance of field studies for an adequate estimation of phytoexclusion potentials.

这项研究评估了原位稳定与植物排他性结合在被金属（Cd，Pb和Zn）和As严重污染且空间异质的农业土地上的实际应用。单一和组合的石灰泥和磷酸盐处理分别种植了两个不同的油菜，小麦和大麦，其微量元素（TE）积累量不同。评估了对土壤酸度，NH ₄ NO ₃可溶性，稻草和谷物TE浓度的影响。联合施肥处理最有效地降低了金属的迁移率，但两种改良剂均不能减轻植物的TE含量，与NH ₄ NO _3的假总含量相关性更高。在土壤中可溶的TE。品种选择分别使大麦或小麦中的Cd降低39％或21％，同时降低了Zn的含量，但反过来影响了小麦籽粒中As的吸收。籽粒TE浓度之间缺乏相关性，这提示了低Cd和As积累而不会引起锌营养不良的育种品种。谷物的单产相对较低，特别是在污染严重的地区，只有油菜和大麦谷物特别适合用于动物。农业措施和气候条件影响了TE的流动性。栽培品种对TE的吸收变化小于温室研究，因此强调了实地研究对于充分估计植物排他潜力的重要性。
