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 ...

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.

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 ...

Hydroxyapatite (Ha) labeling with a phosphorus-32 radioisotope of the TRIGA 2000 reactor irradiation result as a candidate for radiosinovectomy therapy [PDF]

Journal of Physics: Conference Series, 2020
Abstract Radiosynovectomy is a therapy performed on patients with acute-level arthritis (rheumatoid arthritis) as an alternative solution besides surgery. Radiosynovectomy is performed using a labeled compound with a particle size of 0.5-10 μm labeled with a β radioisotope.

Intestinal Phosphorus Absorption in Moderate CKD and Healthy Adults Determined Using a Radioisotopic Tracer

Journal of the American Society of Nephrology, 2021
Significance Statement Reducing intestinal phosphorus absorption through dietary restrictions and phosphate binders is common in managing and preventing CKD-MBD. Yet, how CKD pathophysiology affects intestinal phosphorus absorption is poorly understood.

Effects of benthic algae on release of soluble reactive phosphorus from sediments: a radioisotope tracing study

Water Science and Engineering, 2015
AbstractTo evaluate the effect of benthic algae on soluble reactive phosphorus (SRP) release from sediments in shallow lakes, experiments on SRP release with and without benthic algae in sediment cores and an experiment on SRP uptake by benthic algae were conducted using the radioisotope (32P) tracing method.

Evaluation of Effects of Phosphorus Concentration on Microbial Population and Material Flux in Aquatic Microcosm Using Radioisotope Tracer

Japanese Journal of Water Treatment Biology, 2003
In this study, effects of phosphorus concentration on aquatic microcosms were evaluated in terms of microbial population dynamics and the photosynthetic activity that is the starting point of the material flux. Microcosms that consist of algae Chlorella vulgaris, bacteria Pseudomonas putida and ciliate Cyclidium glaucoma were incubated using media that

Lower and slower: Quantifying phosphorus leaching from struvite relative to monoammonium phosphate by 33P radioisotopic labeling

Geoderma
Struvite (NH4MgPO4·6H2O) is a slow-release phosphorus (P) fertilizer hypothesized to reduce nutrient leaching losses relative to highly water-soluble counterparts such as monoammonium phosphate (MAP). We assessed the leaching fate of P from struvite relative to MAP using soil column experiments for two soils representative of the United States Maize ...

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 ...
