Agricultural terraces are the most widespread archaeological landforms worldwide. Despite their far-reaching prevalence in many inhabited parts of world, soils (hereafter ‘terrace soils’) scarcely studied and nature is poorly defined. This study aims to depict a space–time framework for development calcareous stone-wall bench suggest modifications soil classification mapping. To do so, we exami...
Mirak (Semnan, Iran) is a Paleolithic site located in a dry floodplain near the northern edge of the Iranian Central Desert. The pedo-sedimentary successions of Mirak 8 are deposited from late Pleistocene to Late Holocene,. The chronological framework was established using optically stimulated luminescence (OSL) dating. The oldest studied units dating back to ~50 ± 3.0 ka. Within this stratigra...
این تحقیق طی سالﻫای 81-1380 در دشت سیلاخور لرستان انجام گرفت. بیست خصوصیت فیزیکی و شیمیایی در 25 پروفیل خاک واقع در مساحت 100 هکتار مورد ارزیابی قرار گرفت. خاکﻫا در دو ردة انتیﺳول (Entisols) و اینسپتیﺳول (Inceptisols) قرار گرفتند. بررسی خاکﻫای منطقة مطالعاتی منجر به جداسازی پنج زیرگروه، هشت خانواده و 17 سری خاک شد. در این مطالعه از روش پارامتریک برای ارزیابی تناسب اراضی استفاده شد. همبستگی نسب...
Using data from a water-balance instrument cluster with spatially distributed sensors we determined the magnitude and within-catchment variability of components of the catchmentscale water balance, focusing on the relationship of seasonal evapotranspiration to changes in snowpack and soil moisture storage. Co-located, continuous snow depth and soil moisture measurements were deployed in a rain–...
The current investigation aims to identifying the land and water resources in some areas of Ismailiya governorate. This study covers soil geomorphological pedological characteristics including classification, capability evaluation assessment suitability for certain main crops. integration Remote Sensing (RS) Geographic Information System (GIS) techniques were used perform this work. The int...
Soil ecosystem services (ES) (e.g., provisioning, regulation/maintenance, and cultural) disservices (ED) are dependent on soil diversity/pedodiversity (variability of soils), which needs to be accounted for in the economic analysis business decision-making. The concept pedodiversity (biotic + abiotic) is highly complex can broadly interpreted because it formed from interaction atmospheric diver...
New Guinea is the world’s largest, most speciose, and culturally rich tropical island, little-studied Mamberamo Basin of Papua (Indonesian Guinea) recognised among region’s most-important areas for biological diversity. Here, we examined floodplain forests in indigenous territory Papasena, within Mamberamo-Foja Wildlife Reserve Basin. As part a training activity with local researchers, students...
Extended abstract 1- Introduction Climate, terrain condition, vegetation coverage, parent materials, and time are among the factors that affect the soil formation and contribute to such soil properties as porosity, apparent and actual specific gravities, and clay and carbonate contents. The forest soils have been consistently regarded for their high content of organic matter and suitable stru...
The objective of this study was to establish baseline concentrations for 15 potentially toxic elements (Ag, As, Ba, Be, Cd, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Se, and Zn) based on 448 representative Florida surface soils using microwave assisted HNOrHCI-HF digestion. Baseline concentrations of those elements were (mg kg-I): Ag 0.072.50, As 0.02-7.01, Ba 1.67-112, Be 0.04-4.15, Cd 6-0.33, Cr 0.89-8...
Taxonomic and geographic distributions of background P concentration in soils are important when Taxonomic and geographic distributions of background P concendeciding whether a site is influenced by anthropogenic trations are important in assessing whether a soil P level is influenced by anthropogenic activities. This study was conducted to establish an input of P. Knowledge of background conce...
