Описание: Environmental factors such as drought, elevated temperature, salinity, soil acidity and rising CO2 are known to dramatically affect the symbiotic process and thus play a part in determining the actual amount of nitrogen fixed by a given legume in the field.

Описание: This book takes an in-depth look at diverse plant-phosphorus interactions in natural and agricultural environments. It presents a wealth of information on the genetic and phenotypic variation in natural plant ecosystems adapted to low P availability.
This book focuses on the development of DGT (diffusive gradients in thin films) and the related techniques for measuring and investigating the geochemical process and P transfer across the sediment/water or sediment/root interface in lakes. A series of DGT techniques such as new types of probes, test methods in sediment or the rhizosphere, DIFS (DGT induced fluxes in sediments and soils) model for kinetic P exchange, CID (computer imaging densitometry) for S(-II), and microchelex gel/LA-ICP-MS (laser ablation inductively coupled plasma mass spectrometry) have been developed.
The corresponding chapters on the theory and methodology of DGT, the "internal P loading" or P transfer across sediment/root in two lakes, provide insights into the research method and conclusions, including the P release mechanism, the quantification of "internal P loading", kinetic P exchange in DGT/sediment interface, Fe- or S(-II)-microniches at submillimeter scales in sediments for the prediction of P release, and DGT as a surrogate for the prediction of P uptake by roots.
It also offers new perspectives in the fields of P analysis and P process in micro-interfaces in lakes using DGT techniques. The P remobilization from Fe-bound P, the coupled Fe-S(-II)-P geochemical reaction and algae biomass breakdown causing P release, are elucidated using DGT methods in sediment layers. DGT parameters and curves for time or distance derived from DIFS can be used to assess kinetic P release in the sediment microzone. CID and LA-ICP-MS methods deliver Fe- and S(-II) images at submillimeter scales, which can be used for the quantification of flux related to microniche peaks and the prediction of P release from Fe-microniche or Fe-S(-II)-P geochemical reactions. DGT measurements in-situ in rhizosphere or rhizonbox can give CE (effective concentration) and CDGT values for the prediction of P accumulated in plant tissues.
This book provides a valuable reference resource for senior graduate students, lecturers and researchers in the fields of the geochemical process of eutrophic elements in lakes, lake eutrophication mechanism and environmental analysis.

Описание: There are areas of the world where N fertilizers are neither available nor affordable and, in most of these countries, balance of payment problems have resulted in the removal of N fertilizer subsidies. This book outlines sustainability issues that dictate a use of biological nitrogen fixation and the constraints on its optimal use in agriculture.
Описание: Contains papers on biological nitrogen fixation (BNF) in crop forage and tree legumes. This book discusses the integrated farming systems involving BNF, soil and N management, and recycling of legume residues. It also discusses BNF by non-legumes, and reviews the attempts to transform cereals into nodulating plants.

Описание: The Instituto Internacional de Estudios Avanzados, founded by decree of the President of the Republic of Venezuela, Dr. Luis Herrera Campins, on November 15, 1979 and constituted on July 8, 1980, sponsors, within the Educational Program for the Third World Coun- tries, a series of courses on Scientific Basis for Agricultural Pro- ductivity, the first of which "BIOLOGICAL NITROGEN FIXATION AND ITS ECOLOGICAL BASIS," was held in Caracas on January 18-29, 1982. We are pleased to present, in this volume, the proceedings of this course. It is a pleasure to thank each and everyone of the persons who collaborated in the realization of this event, espe- cially: Dr. Martin Alexander (Cornell University, U.S.A.); Dr. Luis Bascones (FUSAGRI, Venzuela) and Dr. Ivan Casas (Universirlad del Zulia, Venezuela), who assisted me during the preparation and exe- cution of this activity; the teaching staff, whose presentations are the chapters of this volume; and the participants from Argentina, Brazil, Colombia, Costa Rica, Egypt, Ghans, Guatemala, India, In- donesia, Mexico, Nicaragua, Nigeria, Pakistan, Peru, Syria, and Venezuela who shared this course with us. Special recognition is given to UNESCO and FUSAGRI for their valuable contribution. I sincerely hope this publication will be the first of a series on the same level that will originate from the courses in this same program.
Описание: Addressing poverty alleviation via the expanded use of biological nitrogen fixation in agriculture was the theme of the 15th International Congress on Nitrogen Fixation. The 15th International Congress on Nitrogen Fixation was held jointly with the 12th International Conference of the African Association for Biological Nitrogen Fixation.
