Abstract Today, the role of soil and water conservation in increase the vegetation and decrease the soil degradation due to its effect in stabilizing soil has a special place. Vegetation can act as a buffer between the land surface and raindrops or prevent the direct impact of raindrops on the soil surface to prevent the phenomenon of disintegration of soil particles and eroding disperses. The ...

Kavir Biosphere Reserve covers an area of 686598 hectares situated in the northwest of Dasht-e-Kavir and east of Daryach-e-Namak. The Biosphere Reserve presents a variety of habitats, including cliffs and rocky outcrops, piedmont plains, gravelly, deserts and sand dunes, saline plains and salt marshes, and seasonal rivers and springs. The main aim of this research is to identify the plant speci...

The general characteristics of salt-affected soils and soil structure degradation process are partially known, but the effects of saline and sodic conditions on mechanical properties of soils are not well recognized. In this study, the effects of electrical conductivity (EC) and sodium adsorption ratio (SAR) on tensile strength of soils with different organic carbon contents were assessed under...

GIS and remote sensing technique with using Landsat 8 images data are very important methods for detection of geothermal resources. In this study, Land Surface Temperature (LST) for Ardabil province in northwest of Iran, was derived with the use of Landsat 8 Operational Land Imager (OLI) of 30 m spatial resolution and Thermal Infrared Sensor (TIRS) data of 100 m spatial resolution. We consider ...

  conditions. Thus, these varieties could be suitable option for yield increase and an effective step toward food security. Selection of parental lines has essential role in developing ideal combinations. Therefore, it is essential to study the relationship and genetic diversity among parental lines in hybrid rice. Sixteen hybrid rice parental lines including 6 restorer lines (Poya, Sepidrud, P...
