Today, climate change and global warming caused by the emission of greenhouse gases is a big challenge to the world, especially in arid and semi-arid area. Afforestation is the most effective strategy to absorb carbon dioxide in terrestrial ecosystems and reduce global warming of the earth. The purpose of this study is to evaluate the effects of planting Eucalyptus camaldulensis and Amygdalus s...

There are 34 endemic species of Nepeta in Iran, which one of them is Nepeta asterotricha. The present study evaluate different parameters including topography, climate factors, phenology, quantified properties of vegetation variation, physical and chemical properties of the soil at eight natural habitat of the plant in Yazd province. According to the study habitats, the results showed that the ...

One of the main objectives of soil classification systems is to identify the differences of soil properties for management purposes. In this study, the efficiency of American and WRB soil classification systems were compared in order to describe some of soil physical, chemical and mineralogical properties in arid and semiarid regions of central Iran. Khatoon-Abad and Mobarekeh plains as arid re...

Soil physical and chemical properties are the most important factors affecting plant growth Considering variability of soil properties in different areas, investigation on their effects on the plant growth is important, therfore, in this study the contribution of soil factors affecting the unwanted and invasive species in Lashgardar region at Hamedan province was investigated. Sampling was perf...

Flood spreading is one of the suitable methods to control the floods and conservation of soil and water in arid and semi-arid regions. Since soil properties may be influenced by the flood spreading, this study was carried out to investigate the effect of the flood spreading on physicochemical soil properties in Garacharyan plain located in North West of Zanjan in 2009. Three flooded areas and o...
