Relationship between Zn and Cu Contents in Oat Plants and Soils The Zn concentration in oatplants at the stage of appearing panicles from agricultural fields were higher and more varying on soils of sandy texture than on soils of loess. With the former Zn in plants correlated with n‐MgCl 2 extractable Zn in the soil (r = 0.745), and also with 0,5 n‐HNO 3 extractable Zn if the pH dependance was taken into account. Zn in plants from soils of loess correlated with HNO 3 extractable Zn only. Cu concentrations in plants were lower on soils of sandy texture. A correlation to 0.5 n‐HNO 3 extractable Cu in the soil existed in the group of loess derived soils only (r = 0.474), a negative correlation between Cu in plants and soil pH only with sandy soils (r = —0.500). Zn and Cu concentrations of plants were based on total N contents of plants instead of on dry matter, with the aim of mitigating growth dependent differences in Zn and Cu originating from unequal stage of plant development at harvesting.
