Chromium from Hydrolyzed Leather Affects Soybean Growth and Nodulation

摘要: Abstract Hydrolyzed leather, obtained from industrial leather waste, is an organic nitrogenous fertilizer with a high chromium (Cr) content. Soybean crops can be adversely affected by the presence of residual Cr in soil after application hydrolyzed fertilizer. The aim this work was to assess effect on absorption, root development, and symbiotic nodulation soybean plants grown three different soils including two Lixisols Gleysol. These were previously fertilized at rates (0.0, 0.1, 0.8 kg m−2). shoot height, nodulation, mineral nutrient concentrations plant tissues determined 45 d crop growth. significantly increased content uptake plants. Surprisingly, stored mainly aerial part had adverse impact dry matter (41% reduction) number nodules (49% per lowest cation exchange capacity. However, no other significant observed nodule weight, diameter, or any measured parameters.
