Radiophosphorus Metabolism of Different Phosphate Compounds in Experimental Animals
, 1970 Radiophosphorus studies were conducted in rats and hamsters to investigate the metabolic activity of various inorganic phosphates. Significant differences were observed in the metabolic availability and use of phosphate provided as various inorganic ...

Use of Radiophosphorus and Soil-Block Techniques to Measure Root Development
, 1971 A radiophosphorus and soil-block technique of root study gave comparable results when studying root growth of switchgrass (Panicum virgatum) and sideoats grama (Bouteloua curtipendula).

A new technique for the separation of radiophosphorus from sulfur [PDF]
, 1952 A new approach to the separation of radiophosphorus from sulfur has been found which makes a unique use of ion exchange resins. Separations using resin columns are especially suited to problems involving radioactivity since they require a minimum of ...

THE USE OF RADIOPHOSPHORUS, P32, TO MEASURE PHOSPHORUS UTILIZATION BY LAYING HENS
, 1948 Phosphorus utilization in four laying hens has been studied by means of radiophosphorus (P32), which was incorporated into the laying mash as tricalcium phosphate replacing the bone meal in the diet.

Phosphorus chemistry under aerobic and anaerobic conditions in model two-celled waste stabilization ponds. [PDF]
, 1980 This study involved a laboratory examination of the phosphorus interactions between the sediment and water as they occur on a diurnal basis in a waste stabilization pond under summer conditions in the southcentral U.S.
