The uptake of micronutrients, B, Co, Cu, Mn, Mo and Zn, was studied in a pot experiment. The micronutrient concentrations of Italian ryegrass (Lolium multiflorum L.) ranged as follows: B 4.9-11.1, Co 0.01-2.30, Cu 2-15, Mn 29-225, Mo 0.01-1.79 and Zn 23-75 mg kg-1 DM. The micronutrient concentration of plant was compared with the AAAc+EDTA-extractable concentration in soil by soil type. The copper and zinc concentrations of ryegrass correlated stongly with the respective concentrations of all four soil type groups. The respective correlations of boron and manganese were good except in the silt soil group. Cobalt correlated best in coarse mineral and clay soils and molybdenum in clay and organic soils. Boron, cobalt, manganese and zinc conce...
