Radioisotopes Laboratory

The Lab

The Lab was created in 1961 pursuant to an agreement between the UBA and the National Atomic Energy Commission. Its aim is to provide assistance to the School divisions in works involving the use of isotope tracers in agriculture. As time went by, this activity was further defined and it now focuses on soils and is currently part of the Soils Division.


The main aim is to carry out basic or applied studies on soils applying isotope techniques.
Regarding teaching activities, the Lab participates in the course on Isotope Techniques in soils and cultures in the Master in Soils, given at the School of Agronomy.


  • Professor in charge: Agr. Eng. Roberto Alvarez

The Lab depends from the Department of Agriculture Engineering and Land Use; the three head professors of these divisions are members of the directing committee.

The activities performed at the Lab are financed by the UBA, CONICET and CAFPTA.
