THE ASSESSMENT OF MOLYBDENUM – CONTAINING COMPOUNDS
PHYTOTOXICITY FOR LEGUMES ON THE EXAMPLE OF WHITE
CLOVER SEEDS
Molybdenum is one of the most vital microelements in the growth cycle of legume
plants. The article analyzes the phytotoxicity of molybdenum – containing
junctures for legumes. The research findings depict the effect of molybdenum-
containing compounds on white clover seeds in their initial and further stages of
growth. The study systematically explains the response of white clover seeds to
different concentrations of molybdenum in tested solutions. The paper includes
calculations of phytotoxicity in the case of each concentration. In the data
visualization, the author documents the optimum concentration of molybdenum in
solutions for the normal growth of white clover.
Keywords: legume plants, molybdenum, molybdenum-containing compounds,
white clover, phytotoxicity.
INTRODUCTION
The natural biogeochemical circulation of substances is a cycle of interconnected
transitions and transformation of chemical elements occurring within the
components of the environment. The basis for the stability of ecosystems and their
normal functioning is secured by maintaining the balance between chemical
compounds and their optimal concentrations in the natural components. A fairly
large number of chemical elements take part in the biogeochemical processes.
Microelements, one of which is molybdenum, are of particular interest in this
respect. Molybdenum is a chemical element of Group 6 of the Mendeleev Periodic
System [1]. In nature, this trace element exists in the form of various compounds,
the most common of which are MoS2 and MoO3 [2]. Molybdenum is actively
involved in the process of nitrogen fixation in legume plants [3]. This trace
element is contained in environmental objects in a quite small quantity; however, it
performs an important role in ensuring the functioning of the fundamental
