At a time when food is becoming increasingly scarce in many parts of the world and food prices are skyrocketing, no industry is more important than agriculture.

In 1900, 30 million American farmers tilled the soil or tended livestock; today there are fewer than 4.5 million farmers who feed a population four times larger than it was at the beginning of the century. Fifty years ago, the planet could not have sustained a...

The Late Chalcolithic is a period of far-reaching changes in many aspects of life in Mesopotamia. On the southern alluvial plain (present day Iraq) the first city states appear, among them the city of Uruk, which grows to become the largest of the citiesin the south.

Human activities have dramatically changed the composition and organisation of soils. Industrial and urban wastes, agricultural application and also mining activities resulted in an increased concentration of heavy metals in soils. How plants and soil microorganisms cope with this situation and the sophisticated techniques developed for survival in contaminated soils is discussed in this volume.

The topics presented include: the general role of heavy metals in biological soil systems; the relation of inorganic and organic pollutions; heavy metal, salt tolerance and combined effects...
