Soil classification systems are not consistent among countries or organizations thereby hindering the communication and organizational functions they are intended to promote. The development of translations between systems will be critical for overcoming the gap in understanding that has resulted from the lack of a single internationally accepted classification system. This paper describes the ...

The paper reviews a set of soil surveys carried out in Iran using a geopedologic approach for different surveying aims in different scales. Most of these studies have implemented a similar survey method including the following steps: delineation of landforms from air photos using geomorphic and soil-landscape relationships, field check of the delineations, sample areas inventory with soils clas...

Understanding patterns in the distribution and abundance of functional traits across a landscape is of fundamental importance to ecology. Mapping these distributions is particularly challenging for species-rich groups with sparse trait measurement coverage, such as flowering plants, insects, and microorganisms. Here, we use likelihood-based character reconstruction to infer and analyze the spat...

background and objectives : zeolite is a group of anionic hydrated aluminosilicates with a tridimensional structure which has great implications in remediation of water, sediment and soil resources. the present research aims at physicochemical investigation, clay mineralogy and micromorphology of soils along rafsanjan-sarcheshmeh lithotoposequence, southeastern iran. materials and methods: the ...

BACKGROUND Soils are widely recognized as a non-renewable natural resource and as biophysical carbon sinks. As such, there is a growing requirement for global soil information. Although several global soil information systems already exist, these tend to suffer from inconsistencies and limited spatial detail. METHODOLOGY/PRINCIPAL FINDINGS We present SoilGrids1km--a global 3D soil information...

The type species of the genus Zambedania Mahunka, 1972 (Z. africana Mahunka, 1972) is redescribed based on the holotype collected from soil in Zimbabwe. Two new species are described and illustrated herewith: Z. madagascariana from Madagascar and Z. argentiniana from Argentina. The generic diagnosis of Zambedania is amended, and the key to its species is supplied. Morphology, taxonomy and biolo...

A recent trend towards greater automation of earthmoving machines, such as backhoes, loaders, and dozers, reflects a larger movement in the construction industry to improve productivity, efficiency and safety. This document reviews related work in various disciplines drawn upon by researchers— soil mechanics, computer graphics, kinematic and dynamical modeling, optimization, control and decisio...
