Information of spatial and temporal variations of soil quality (soil properties) is required for various purposes of sustainable agriculture development and management. Traditionally, soil quality characterization is done by in situ point soil sampling and subsequent laboratory analysis. Such methodology has limitation for assessing the spatial variability of soil quality. Various researchers i...

The identification of freezing-thawing soil hydraulic properties is the basis and key problem of studying soil water movement. Current identifying methods of the properties have many limitations, such as big error, high uncertainty and low operability. Thus, the identifying method of freezingthawing soil hydraulic properties was researched in the research. The estimating parameters of soil free...

The legislations have been promulgated in many states that remove barriers to large-scale beneficial re-use of waste materials. As a result, there is a renewed emphasis on incorporating suitable waste products into highway construction. Fly ash is one of these materials, and is increasingly being used as fill materials for highway embankments, and as grout mixes for road bases. In most cases, a...

• We studied the relationships of plant and AMF (arbuscular mycorrhizal fungi) species richness and community composition to each other and gradients in soil texture, nutrient content, and light availability in three oak savannas in southern Wisconsin, USA. • Sixty-three samples were analysed for plant and AMF composition along sun–shade and sand–loam gradients. Samples consisted of plant commu...

Short title for page headings: Influence of the rhizosphere on soil hydraulic properties 16 17 Short statement: Using non-destructive imaging techniques and numerical modelling we 18 quantify differences in hydraulic and structural properties of bulk and rhizosphere soil for 19 sand and clay loam soils. 20 21 22 2 1. Abstract 23 Understanding the dynamics of water distribution in soil is crucia...

Interrelated, biotic (flora and fauna) and abiotic (pedogenesis and hydrology) processes were examined at four sites (30, and approximately 1000–3000, 7000–12 000, and 125 000 years before present) in the northern Mojave Desert. Data collected at each included floral and faunal surveys; soil texture, structure, and morphology; and soil hydraulic properties. Separate measurements were made in sh...

introduction soil infiltration rate is the major soil hydraulic property which can be affected by the soil physical characteristics and management practices. the use of land can affect various soil properties such as physical and hydraulic properties. differences of the hydraulic soil characteristics such as infiltration rate in various land uses can affect their potential to runoff production ...
