Head: Uri Nachshon, Ph.D.
Aims: Research in soil chemistry, fertility, crop productivity and microbiology for sustainable agricultural use of soil and water resources and environmental protection; dissemination of knowledge; instruction and training of graduate and postgraduate students.


Sustainable use of soil and water resources through excellence in research

Major research fields:

1. Optimized use of nutrients and water resources in managing soil and crops, while preserving environmental quality;
2. Impacts of marginal waters, organic wastes and industrial by-products on crop production and soil quality;
3. Fate and behavior of pesticides and other organic chemicals in soil and water bodies;
4. Soil and water conservation;
5. Physiological responses of crops to environmental stresses, especially drought and salinity
6. Soil microbial ecology as affected by agricultural practices.
