Nine pedons and 30 surface samples were taken, described, and analyzed to investigate the effect of desertification on soil quality indices, mineralogical, and micromorphological properties of three regions (desert, semi-desert, non-desert) in central Iran.
Electromagnetic induction has been used to characterize the spatial distribution of salinity. However, most studies have been undertaken to map the areal distribution of the average profile salinity using measurements of the apparent electrical conductivity. In this study, an EM38 was used to map the distribution of salinity with depth.

The present research developed decision tree models for spatial prediction of soil classes in a 720 km2 area located in an arid region of central Iran, where traditional soil survey methods are difficult to undertake.

Drought is a problem of the expanding universe which seriously influences crop production and quality. The present study aimed to determine the effects of drought and rewatering on activities of antioxidant enzymes, chlorophyll, proline, and relative water contents.

The objective of this study was to estimate the mass fractal dimension of the Rieu and Sposito model from readily available parameters, such as clay, silt, and sand contents; geometric mean diameter and geometric S.D. of soil particles; and total soil porosity by developing an artificial neural network model.

In this study the effects of soil binders were investigated using the rainfall simulator and small flume facilities of IRFRI erosion laboratory. . It was found that at steep slopes higher soil binder application rates are required to enhance soil structure stability, to reduce runoff and soil erosion.
