With an ever-increasing human population, the demand placed upon
the agriculture sector to supply more food is one of the greatest
challenges for the agrarian community. In order to meet this
challenge, environmentally unfriendly agroch- icals have played a
key role in the green revolution and are even today commonly
recommended to circumvent nutrient de?ciencies of the soils. The
use of ag- chemicals is, though, a major factor for improvement of
plant production; it causes a profound deteriorating effect on soil
health (soil fertility) and in turn negatively affects the
productivity and sustainability of crops. Concern over disturbance
to the microbial diversity and consequently soil fertility (as
these microbes are involved in biogeochemical processes), as well
as economic constraints, have prompted fun- mental and applied
research to look for new agro-biotechnologies that can ensure
competitive yields by providing suf?ciently not only essential
nutrients to the plants but also help to protect the health of
soils by mitigating the toxic effects of certain pollutants. In
this regard, the role of naturally abundant yet functionally fully
unexplored microorganisms such as biofertilizers assume a special
signi?cance in the context of supplementing plant nutrients, cost
and environmental impact under both conventional practices and
derelict environments. Therefore, current devel- ments in
sustainability involve a rational exploitation of soil microbial
communities and the use of inexpensive, though less bio-available,
sources of plant nutrients, which may be made available to plants
by microbially-mediated processes.
