Content of copper and molybdenum in forage plants of winter pastures of the Nakhchevan Autonomous Republic

The amount of copper and molybdenum was determined in samples of grass collected from the winter pastures of Bashbashi and Negram. As a result, the norm of copper content (5.3-11.8 mg per 1 kg of air-dried grass) and molybdenum (3.8±0.8-7.8±0.8 mg) was determined. Of the food plants, wormwood contains the most molybdenum, and copper-accumulating plants include wormwood and legumes. Forage plants of the Bashbashinsky and Negramsky winter pastures accumulate sufficient amounts of copper. Its content varies in the grasses of winter pastures of Bashbashinsky from 6.0 mg to 8.3 mg, on average 6.7-7.6 mg, in Negram from 3.8 mg to 12.6 mg, on average 5.3-11.8 per 1 kg of air-dry material. Wormwood and legume formations are the richest in copper.
