The presence of different forms of heavy metals in the earth crust is very primitive and
probably associated with the origin of plant life. However, since the beginning of human …

Of all the non-essential heavy metals, cadmium (Cd) is perhaps the metal which has
attracted the most attention in soil science and plant nutrition due to its potential toxicity to …

Heavy metal toxicity is one of the major abiotic stresses leading to hazardous health effects
in animals and plants. Because of their high reactivity they can directly influence growth …

Copper (Cu) is a heavy metal which in recent studies has been attributed an increasing role
in metabolic processes of plant cells. It is an indispensable component of oxidative enzymes …

Legumes are important for nitrogen cycling in the environment and agriculture due to the
ability of nitrogen fixation by rhizobia. In this review, we introduce an important and potential …

The antioxidant defence system of soybean (Glycine maxL.) nodules and roots was studied
in plants subjected to three different concentrations (50, 100 and µ200 M) of CdCl 2 …

All strains of Rhizobium isolated from ineffective nodules on white clover (> 50 separate
isolations) formed in metal-contaminated soils from a field experiment were demonstrated to …

The influence of the arbuscular mycorrhizal fungus (AMF) Glomus macrocarpum Tul. and
Tul. on Bradyrhizobium-inoculated soybean (Glycine max L. Merrill var. IAC-14) growth …

Experiments were conducted to investigate the phytotoxic effects of heavy metals on
chickpea, grown in unsterilised soils. Cadmium at 23 mg/kg soil, when used alone or in …

When petroleum hydrocarbons contaminate soil, the carbon: nitrogen (C: N) ratio of the soil
is altered. The added carbon stimulates microbial numbers but causes an imbalance in the …
