A greenhouse pot experiment was conducted to evaluate the effect of biochar on the growth and uptake of Pb and Zn by tomato plants (Solanum lycopersicum, L.) cultivated in two highly contaminated Kosovo soils, A and B. Plants were cultivated in the biochar amended and unamended soils. As expected, the biochar addition to the two polluted soils has contributed to significantly improve the crop yields, in terms of both fresh and dry weight. Further, results indicated that the effect of biochar on metal mobility is closely related, besides its properties, to soil’s native characteristics. In fact, the addition of biochar to soil B had also beneficial effects on the uptake of both metals, halving in some cases the values of the biological accumulation and transfer coefficients, while it did not show the same efficacy on soil A.

进行了温室盆栽实验，以评估生物炭对番茄植物（茄子，L.）种植在两种高度污染的科索沃土壤中，即A和B。将植物种植在经过生物炭改良和未经改良的土壤中。不出所料，无论是鲜重还是干重，向两种污染土壤中添加生物炭都有助于显着提高农作物的产量。此外，结果表明，生物炭对金属迁移率的影响除其性质外，还与土壤的自然特征密切相关。实际上，向土壤B中添加生物碳对两种金属的吸收也具有有益的作用，在某些情况下，生物积累和转移系数的值减半，而对土壤A却没有相同的功效。
