RESEARCH


In the List of Publication section there is a list of the research topics that I worked in the past. Also in the C.V. section there is a description of the different research projects I had been involved.

I am currently working in Professor Richard E. Plant lab (UC-Davis, Agronomy and Range Sciences Department) trying to quantify the overlaying factors that cause California and Uruguay spatial and temporal rice variability, with the goal of evaluating the possibilities of the adoption of Precision Farming techniques already available in other regions.

My current themes of interest with-in this area are:

- Precision Farming

- How to quantify spatial and temporal variability

- How to quantify rice fields stochastic and deterministic yield spatial patterns and their stability through time.

- How to quantify the major factors underlying the observed spatio-temporal variability.

- ECOLOGICAL TRADE-OFFS OF DECREASING YIELD VARIABILITY /INCREASING CROP UNIFORMITY.

- Management Zones

- Geostatistics

- GIS applications in Agriculture

- Scale
