Phosphorus is an essential plant nutrient, but global population
growth has dramatically reduced the availability of phosphorus
fertilizer resources. Despite this scarcity, there remain numerous
problems associated with the excessive and inappropriate use of
phosphorus leading to non-point source pollution and eutrophication
of natural waters. Identifying appropriate systems for managing
soil phosphorus and reducing the risks of eutrophication are needed
to minimize the environmental risks. This book focuses on the
availability and recycling of phosphorus; regulatory and policy
issues of sustainable phosphorus use; and water quality management
in agroecosystems pertaining to phosphorus. Sections are dedicated
to global phosphorus reserves; cycling and pathways of phosphorus;
phosphorus in agriculture; human dimensions and policy
intervention; and research and development priorities. Phosphorus
is a finite but crucial resource and is an essential element to all
life. Sub-optimal availability and nutrient imbalance in the root
zone can adversely impact plant growth, and the quality of food and
feed grown on these soils. However, the proven reserves of
phosphorus can hardly be adequate for a few centuries only. Yet,
its misuse and mismanagement has caused severe problems of
eutrophication of water and pollution of the environment. Thus,
judicious management of soil phosphorus is essential. This volume
is specifically devoted to availability and recycling of
phosphorus, regulatory/policy issues of sustainable use of
phosphorus, and management in agroecosystems in the context of
maximizing the use efficiency and minimizing the environmental
risks of water quality.
