Determination of soil moisture content is of vital importance to many fields of study; civil engineering, hydrology, agriculture, geology, ecology and forestry. The occurrence of impact crater in Bukit Bunuh, a meteorite impacted area, made it an area of great interest to many researchers. In view of the process of impact cratering, the subsurface soil characteristics such as moisture content o...

In order to investigate the diversity of plant species in forested areas, this study was carried out in forestry near the Khuzestan Steel Industries Company with a total area of 60 hectares in the southeast of Ahwaz, Khuzestan province. For this purpose, 30 plot of 20 × 20 meters in size were systematically randomized in the forested area and 30 samples were taken in the control area. Within ea...

Soil or relative percentage of sand, silt and clay reflects some texture characteristics such as permeability, water holding capacity, CEC, and soil behavior in return to the plow and other tillage operations is very important. The study area covers an area of 1715.4 hectares, near the Aiej soil dam, East of Jooneghan city, Chaharmahal and Bakhtiari Province. For this study, 40 disturbed soil s...

Geopedology is a systematic approach of geomorphic analysis for soil mapping that construct field operation mainly upon the work in sample area. The main goal of this research is to determine the effect of location of sample area and expert knowledge on credibility of generalization of the results obtained from geopedological approach for similar landforms in south-east of Borujen area. Upon pr...

The extent of rangeland is one of the most important characteristics of organic carbon uptake and storage in soil and plants. The present study investigates the indices of plant diversity and organic carbon storage in mountain pastures under grazing and 10-year enclosure in Asadabad. The rangeland is approximately 100 hectares and its rangelands are in good condition and are in the 2S class in ...
