Nowadays a significant amount of land contaminated with toxic elements is being used for agriculture, posing a serious risk of crop contamination and toxicity. Several methodologies are being used to remediate soil contamination, including the use of amendments such as biochar. This work evaluated the effects of biochar combined with different fertirrigations (water, a conventional fertilizer solution, or a fertilizer solution with a commercial biostimulant derived from leonardite) on the availability of toxic elements and nutrients for pepper cultivated in a soil contaminated with As, Cd, Pb, and Zn.

生物炭和生物刺激素对污染土壤中辣椒对养分和有毒元素吸收的协同作用

如今，大量被有毒元素污染的土地被用于农业，对农作物造成严重的污染和毒性风险。几种方法被用于修复土壤污染，包括使用生物炭等改良剂。这项工作评估了生物炭与不同灌溉施肥（水、常规肥料溶液或含有来自风化岩的商业生物刺激剂的肥料溶液）结合对在受砷、镉污染的土壤中种植的辣椒的有毒元素和养分有效性的影响、铅和锌。
