Isotopic-aided studies involve the application of isotopically labelled fertilizer as tracers for
the quantitative and precise determination of the fate of specific nutrient elements in the …

New insights into factors controlling element bioavailability and mobility in soils have been
achieved through the use of isotopic dilution methods. With the advent of robust and …

Enhanced nutrient cycling basically involves close interaction between inorganic and
organic sources of nutrients. Contrasting scenarios of nutrient cycling are found under …

Isotope dilution techniques have been widely applied in research investigating the fate and
availability of different elements in soils. One technique, known as the'E-value'method …

For the past 70 yr, researchers in the Soil Science/Renewable Resources Department at the
University of Alberta have used isotopes to study topics of ecological importance. This …

Isotopes refer to elements with nuclei having the same number of protons, but differing
numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few …

Equipment and procedures for the determination and isotope-ratio analysis of plant samples
enriched in 34 S are outlined, and field data of labelled fertilizer S uptake using stable …

Areas of micronutrient studies in which radioisotopes have been most beneficial are
discussed and examples given. These include measurements of availability, efficiency of …

The short answer to this question is detection. Isotopes allow materials in certain pools (eg
roots) to be distinguished from those in the rest of an experimental system (eg soil). This is …

Two questions of crucial importance both to the farmer and society are fertilizer use
efficiency and fertilizer loss by leaching and/or volatilization. A direct quantitative answer to …
