Stable Isotopes in Plant Nutrition, Soil Fertility and Environmental Studies

Proceedings Series - International Atomic Energy Agency

Description

Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 1–5 October 1990. The objective of the symposium was to evaluate progress in the use of stable isotopes to examine various aspects of soil fertility and plant nutrition and some environmental problems, the potential and limitations of existing methods, and possibilities for further development. The meeting focused on the site level rather than the landscape level and, more specifically, on soil–plant relations, although landscape environmental aspects were also examined. The underlying theme was an assessment of current and possible future approaches to two problems of concern: how to increase or sustain productivity with minimum inputs, and how to limit environmental damage due to inappropriate land management and to industry.
Contents: New methodologies and approaches in stable isotope analysis; Measurement of biological nitrogen fixation using 15N additions; The 15N natural abundance method for measurement of biological nitrogen fixation; Review of papers in Sessions 2 and 3; Applications of 15N methods to measurement of biological nitrogen fixation; Stable isotopes in soil organic matter studies; Soil nitrogen transformations and losses; Nutrient uptake and use by the plant; Stable isotopes in studies of plant metabolism; 13C/12C discrimination as a measure of water use efficiency; 13C in studies of plant carbon balance; Stable isotopes in water transport studies; Sulphur flows and transformations in ecosystems; Atmospheric change and aerial pollutants.
