Use of Phosphorus Isotopes for Improving Phosphorus Management in Agricultural Systems

IAEA-TECDOC-1805 (978-92-0-107416-4)
108 pages ¦ 4 figures ¦ EUR 18.00


Phosphorus is an essential element in plant human and animal nutrition. Soils with low levels of phosphorus are widespread in many regions of the world and the deficiency limits plant growth and reduces crop production and food quality. This publication provides comprehensive and up to date information on several topics related to phosphorus in soil–plant systems in agricultural systems and in the environment. It presents the theoretical background as well as practical information on how to use nuclear and radioisotope tracer techniques in both laboratory and greenhouse experiments to assess soil phosphorus forms and plant available soil phosphorus pools and to understand the cycling processes in soil–plant systems. The publication focuses on practical applications of radiotracer techniques and can serve as resource material for research projects on improving sustainable phosphorus management in agricultural systems and as practical guidance on the use of phosphate isotopes in soil–plant research.
