The influence of waterlogging on the distribution of trace metals in the soil
The thesis is devoted to a consideration of soil
factors influencing the availability of trace metals for
plant uptake, with particular reference to waterlogging.
Chapter 1 includes a brief survey of the roles of trace metals
in biological systems and the forms which exist in soil fractions.
The forms of trace metals influenced by environmental
factors are also discussed. The importance of waterlogging
in influencing the distribution of trace metals is discussed
in more detail, as are the relevant chemical changes taking
place in the soil with various waterlogging times and depths.
The objectives of the thesis are to investigate the effects
of waterlogging on the redistribution of trace metals in soil
and the implications for plant uptake. The case is made out
for this study.
