Research Interests
- Soil structure “A key element in soil functioning” – The studies concentrate on the impact of various agricultural management practices, combined with inherent soil properties, on soil structure & on development of remediating measures to maintain/improve the stability of soil structure.
- Impact of Irrigation with marginal water – 2.1 Effects of long term irrigation with treated wastewater (TWW) on soil and crop in orchards grown in clayey soils. 2.2 Effects of long term irrigation with saline-sodic water on soil sodicity and crop response in orchards.
- Use of Soil Amendments – 3.1 Use of polyacrylamide (PAM) to control runoff and erosion under rain conditions. 3.2 Reclamation of sodic soil in an olive orchard – testing various ameliorating agents (gypsum, polysulphate, sulpheric acid, Ca or Mg–chloride). 3.3 Soil amending with organic wastes – Optimization of compost application rates for prevention of damage to soil structure.
Research Areas
- Soil structure and aggregate stability
- Irrigation with poor quality water (treated waste water and saline-sodic water)
- Use of soil amendments
