Effects of liming and nitrogen application on the Cu,Mn,and Zn concentrations in herbage from extensively managed pastures
Introduction In less intensively managed grassland in Central Europe, the micronutrient concentrations in herbage are apparently more likely to be in levels between barely sufficient and deficient than to be excessively high.Insufficient amounts of selenium, copper, manganese, and zinc cause physiological disorders in ruminants.
