Summary

The book is divided into five parts. The initial portion covers the overview of the sub-ject which addresses abiotic and biotic interactions and the impact on restoration of terrestrial ecosystems and human welfare. Several chapters deal with the roles of abiotic and biotic interactions in the transformations of (a) natural organics and xenobiotics, (b) nitrogen, phosphorous, sulfur, and boron, and (c) metals and metalloids, respectively. The book also addresses the issue on rhizosphere processes which is the bottleneck for sustaining biological productivity and protecting the human food chain.
