This research aimed to evaluate the residual Cu and Zn in tropical soil over 21 years after
amendment with industrial waste, lime, and compost. Soil samples were collected from a …

Several particular plants are suggested to be able to extract significant parts of heavy metals
from soils and accumulate them in their roots and/or shoots. This research aimed to study …

Biochar was suggested to lower the concentrations of heavy metals in contaminated soils
and therefore may improve plant growth. This research was to evaluate the growth of corn …

Biochar shows interesting and environmentally useful properties, among which is its
relatively high cation exchange capacity (CEC). High CEC may lower the easily plant …

Phytoextraction and liming were suggested to decrease the concentrations of heavy metals
in contaminated soils. This research was to study the effects of liming and phytoextraction by …

Increased soil heavy metal concentrations are suggested to cause roots to work harder. This
research was to study the growth and phytoextraction behaviors of elephant grass in soil …

A significant number of plants were suggested potential to alleviate toxic levels of heavy
metals in soils through phytoremediation. This research was to study the phytoremediation …

It was suggested that some tropical plants were able to lower toxic metal concentrations in
soils. The phytoextraction potential of thorny amaranth (Amaranthus spinosus) in tropical …

Copper is reported to be retained in soils for a quite long time particularly in soil treated with
some amendments. This research was intended to evaluate the soil labile fractions of Cu±10 …

Heavy metals may easily move through the air system and may deposit and accumulate in
the soil system by water precipitation away from their sources. This research aimed to …
