The effect was studied of a combination of nitrates and sulphides of heavy metals (Zn : Cu : Pb : Cd : As : Se = 7 : 1 : 0.05 : 0.025 : 0.01 : 0.5) with four increasing applications of Cu (33, 110, 330 and 1100 kg/ha) in soil and in foliar treatments of 10 times less, on the yield of pea-oat mixtures, in an experiment on a gleyed dernopodzolic soil in the Moscow region of Russia. The total heavy metal oxides decreased yields by 30%.
