The role of total Na in the retention of microelements in soils on marine deposits

Abstract

The influence of alkalinity and other factors on the content of microelements in soils developed on marine deposits is studied. Traditional indicators of exchangeable sodium percentage do not demonstrate the ability to retain microelements, but one can see a close direct correlation between the content of macroelements and the retention of microelements. The efficiency of this group is increased if we take into account the concentration of total Na. The element compositions of soil were determined by neutron activation method. The results show that the Na-related alkalinity of soil can enhance the role of the main macroelements and increase the dispersibility of particles and their aggregating capacity relative to the microelements. The microelement composition was also determined in Gleyic Solonchaks using the Zn concentration due to the anionogenic composition of gley.
