Application of Nanotechnology for Improving physical properties of Degraded soils

Abstract

This study aimed to study the effects of nanotechnology on improving the physical properties of degraded soil in Dhi Qar Governorate, which faces environmental challenges such as high salt content, water shortage, and deterioration of the physical structure of the soil. Emphasis has been placed on the use of nano-materials such as nano-silica and nano-clay, improving bulk density, permeability, water conductivity and water-holding capacity of soil. 

 Preliminary results show that nanomaterials contribute significantly to enhancing soil structural cohesion, increasing in-situ capacity, reducing permeability in sandy soil, and improving pore distribution. In addition, the use of nanotechnology has improved water use efficiency and reduced degradation caused by corrosion or erosion. 

The study recommends broader application of nanotechnology in affected areas in Iraq, with a focus on conducting long-term field studies to ensure effectiveness and environmental sustainability. Technology is a promising tool for achieving sustainability of agriculture and water resources in the face of increasing environmental challenges.
