Head: Josef Tanny, Ph.D.
Aims: Improving our understanding, knowledge and ability to quantitatively describe processes in the soil-plant-atmosphere continuum in order to advance agriculture and sustain the quality of soil and water resources.


1. To identify knowledge gaps, to support R&D initiatives, to advance new research directions (basic and applied), to improve our abilities to measure and simulate in the soil-water-plant atmosphere domain, in order to improve water use efficiency, to increase yields, and to constrain pollution and damage to water and soil resources and services.
2. To contribute and strengthen the status of the Institute and the ARO in the research forefront in Israel and the world by publishing the results of research activities in leading journals, establish cooperation with other research centers and organizations, participate in conferences and train students.
3. To create basic and applied knowledge in topics related to the Soil-Water-Plant-Atmosphere continuum (SWPAC) in order to:
a. Improve water and nutrient use efficiency in Agriculture and increase profitability of agriculture
b. To develop soil and water resources and improve their utilization
c. To minimize the impact on environmental quality and contribute to revitalization of polluted natural resources.


Long term interdisciplinary research on:

  • Models for simulating the soil-water-plant-atmosphere continuum
  • Methods for improving water use efficiency and irrigation control
  • Methods for real-time monitoring of soil and crop water status at the plant (precision agriculture) and field level.
