First International Meeting on Microbial Phosphate Solubilization
In 2002, sixty international specialists met to discuss problems of
high P-unavailability as a soil nutrient for crops, and the hazards
of increased phosphate input to aquatic habitats from industrial
and mining activities, sewage disposal, detergents, and other
sources. Among the presentations were updated solutions to enhance
P-uptake by plants, bioremediation potential in the rehabilitation
of ecosystems, taxonomic characterization interactions with
mycorrizae, the physiological and molecular basis of PSM, and
more.Last decade has seen a significantly increased knowledge about
phosphate solubilizing microorganisms. Sixty specialists from
thirteen countries met in Salamanca to discuss the problems of the
high P-unavailability as a soil nutrient for crops, and the hazards
of an increasing phosphate input to aquatic habitats from
industrial and mining activities, sewage disposal, detergents, and
other sources. Updated solutions to enhance P-uptake by plants,
bioremediation potential in the rehabilitation of ecosystems,
taxonomic characterization interactions with mycorrizae, the
physiological and molecular basis of PSM, and possibilities of
genetic modifications of rhizospheric microorganisms were among the
contributions presented. Challenges in commercializing a phosphate
solubilizing microorganism were also outlined by a relevant biotech
company. The book will fill a gap in agricultural libraries and it
is a wish of the editors to attract the attention of agronomists,
environmentalist, technocrats and administrators holding
responsibilities in the field of soil conservation and sustainable
agricultural production.
