Phosphorus acquisition by wheat from organic and inorganic sources labelled with 32P and 33P radioisotopes [PDF]
Scientia Agricola, 2020 : Investment in soil phosphorus (P) capital in the tropics is often constrained by poor availability of mineral fertiliser to small-scale farmers. Consequently, new sustainable agricultural cropping strategies are required to maintain fertility and ...

Phosphorus-32 in the Phage Group: radioisotopes as historical tracers of molecular biology [PDF]
Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2009 The recent historiography of molecular biology features key technologies, instruments and materials, which offer a different view of the field and its turning points than preceding intellectual and institutional histories. Radioisotopes, in this vein, became essential tools in postwar life science research, including molecular biology, and are here ...

Soil solution phosphorus turnover: derivation, interpretation, and insights from a global compilation of isotope exchange kinetic studies [PDF]
Biogeosciences, 2018 The exchange rate of inorganic phosphorus (P) between the soil solution and solid phase, also known as soil solution P turnover, is essential for describing the kinetics of bioavailable P.

Investigation of the Role of Organic Acids on the Phosphorus and Zinc Uptake by Corn in Calcareous Soils by Using 32P and 65Zn Radioisotopes [PDF]
مجله علوم و فنون هستهای, 2014 To investigate the effect of oxalic and citric organic acids on the uptake of Phosphorus and Zinc by corn (Zea mays L.), an experiment was conducted by the use of radioactive potassium phosphate and zinc sulfate fertilizers in microcosm and greenhouse ...

Characterisation of soil phosphorus forms in the soil-plant system using radioisotopic tracer method [PDF]
Plant, Soil and Environment, 2021 Soil incubation and pot experiments were conducted to follow the sorption processes of added phosphorus (P) fertiliser using the radioisotope tracer technique. Increasing doses of P fertiliser (40, 80, 160, 320 mg P/kg soil) were added to Chernozem and Arenosol and incubated for 1, 3, and 13 weeks. After incubation, perennial ryegrass (Lolium perenne L.

Radioisotopes as political instruments, 1946-1953 [PDF]
, 2009 The development of nuclear «piles», soon called reactors, in the Manhattan Project provided a new technology for manufacturing radioactive isotopes. Radioisotopes, unstable variants of chemical elements that give off detectable radiation upon decay, were

Autoradiography of Pi Distribution in Barley Seedlings
Bio-Protocol, 2014 Phosphorus-32 and Phosphorus-33 are radioisotopes of phosphorus. These isotopes are used to trace ionic phosphorus and phosphorus compounds. This protocol is used to follow the movement of inorganic phosphate (PO43-) from a leaf tip to the rest of the ...
