Examines the chemical and biological mechanisms that determine the availability of nutrients to plants. Barber develops a mathematical model for soil nutrient uptake, and discusses eleven plant and soil parameters that affect the rate of flow of the nutrient into the root. Offers practical guidance for applying this model in measuring uptake of 12 different nutrients for any crop and any soil condition.

Metal Speciation and Bioavailability in Aquatic Systems is thefirst comprehensive review to deal with fundamental concepts andmodels, speciation measurements and field applications in metalspeciation and bioavailability in aquatic environments. This volumeprovides a thorough review of current developments concerning theinteractions between trace metals and aquatic organisms. MetalSpeciation and Bioavailability in Aquatic Systems provides: * The first comprehensive approach to the subject covering allaspects of trace metal ecotoxicology in the environment. * Essential reading for researchers and graduate students who willappreciate critical reviews of classical and modern methods ofmetal speciation. * Contributions from leading scientists from many disciplinesassessing both analytical and physical methods applied to thisgrowing field of environmental analysis. * An introduction to the use of laboratory bioassays as predictivetools for understanding trace metal organism interactions. * An examination of the use and limitations of bioassays inmanagement decisions. The interdisciplinary nature of this topic is highlighted in MetalSpeciation and Bioavailability in Aquatic Systems, ensuring thatthis volume is invaluable for chemists, biochemists, biologists,ecologists and environmental engineers involved in the fields ofmetal ecotoxicology, metal speciation, environmental and analyticalchemistry, and the management of trace metals in aquatic systems.

This richly illustrated edition of an established classic deals with the chemistry and biology of soil nutrient availability. Provides information regarding the elements present in soils and the extent to which these elements can be used by plants in order to grow. Nutrient uptake by plant roots, rhizosphere microorganisms and application of the mechanistic uptake model as well as such elements as phosphorus, potassium and water are among the topics discussed.

Oral lipid-based formulations are attracting considerable attention due to their capacity to facilitate gastrointestinal absorption and reduce or eliminate the effect of food on the absorption of poorly water-soluble, lipophilic drugs. Despite the obvious and demonstrated utility of these formulations for addressing a persistent and growing problem of major significance, the pharmaceutical industry has been slow to apply and further develop this technology. This title provides a comprehensive summary of the theoretical and practical aspects of oral lipid-based formulations for use in industry, and provides further insights into a developing technology expected to assume increasing prominence in years to come.
