Influence of the cultivation measures and international level to content of Cu, Mn, Mo on the tea plantation soil
Total content of Cu, Mn, Mo in soil profiles depends closely on mother rock. The cultivation measures and intensification level not exist evident influence on the total content of these elements. Mn-exchangeable form reduces gradually with soil depth together with organic matter content. Reducible content of Mg at pH 1,0 and pH 8,0 is directed to increase according to the soil depth together with the increase of physical clayey particles. The Mo ad Cu-available content in the most soil profiles decreased with soil depth.
