Trtts review cites some of the uses to which isotopes have been put during the past 15 years
by the Hawaiian sugar industry. No attempt will be made to give in detail the methods and …

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 …

The applications of radioactive isotopes to studies in soils and plant nutrition are reviewed.
These include experimental work on the direct tracing of gross transport of salts in living …

RADmACTXVE isotopes of biologically significant elements have now been available for
over 20 years. One of the early uses of these isotopes was in tracer studies of the mineral …

By supplying a particular leaf of variously aged sugar cane plants with C14O2, it was shown
that translocation covered the whole of a large single-stalked plant in less than 18 hours …

requires that the radiolabel be described as a function of concentration. This chapter …

When a small volume of solution containing a carrier-free radioactive isotope is injected into
soil, the radioactive ions equilibrate with labile ions of the same type near the point of …
