Glyphosate is a widely used herbicide, but its drift can cause growth depression in sensitive plants such as wheat by reducing uptake of metallic micronutrients, particularly manganese. In pot and field trials, this project aims to assess the alleviating potential of fulvate and manganese on growth and micronutrient uptake by wheat exposed to glyphosate drift. The influence of land management on the effect of these treatments will also be assessed. The underlying mechanisms will be characterised, eg. by determining metal speciation in soil and assessing soil microbial community composition. The outcome of this project will contribute to sustainable agriculture by giving land managers options to reduce glyphosate damage in sensitive crops.

草甘膦是一种广泛使用的除草剂，但其漂移会减少金属微量营养素（尤其是锰）的吸收，从而导致小麦等敏感植物生长抑制。在盆栽和田间试验中，该项目旨在评估黄腐酸盐和锰对暴露于草甘膦漂移的小麦生长和微量营养素吸收的缓解潜力。还将评估土地管理对这些处理效果的影响。将描述基本机制的特征，例如。通过确定土壤中的金属形态并评估土壤微生物群落组成。该项目的成果将为土地管理者提供减少草甘膦对敏感作物损害的选择，从而促进可持续农业。
