the effect of soil moisture content (in primary tillage) and travel speed during disking operation on performance of disk harrow as a secondary tillage tool

this study was conducted to investigate the effect of soil moisture content in primary tillage and travel speed during disking operation on the performance of an offset disk harrow in a silty clay loam soil. at first, the effect of three soil moisture content ranges of (12-14), (

combining topographic and soil attributes for spatial prediction of model parameters of soil shrinkage curve

this study was conducted to investigate the spatial variability of model parameters of soil shrinkage curve in cherlgerd district, chaharmahal-va-bakhtiari province. ninety nine locations were selected and soil clods were collected from the 0-10 cm layer and brought to the labora

A simpli®ed method for analysing the mechanics of clod: clod interactions in topsoils with a wide range of clay content

Classical concepts of mechanics applied to continuous materials cannot be used directly for associations of soil clods occurring in ploughed and harrowed topsoils. Therefore, we are proposing a new simpli®ed method for analysing the clod : clod mechanics, for a wide range of clay

Grundmann Et Al.: Spatial Modeling of Nitrifier Microhabitats in Soil

plexity of soil affects the probability of bacteria encountering appropriate substrates or other bacteria. The Soil bacteria function in the three-dimensional space in heterogequantitative assessment of bacteria in soil is mostly conneous soil complex and their activities depend

Measuring and modelling the soil shrinkage characteristic curve

The macroporosity, and to a lesser extent the microporosity, of swelling and shrinking soils is affected by their shrinkage behaviour. The magnitude of the changes in bulk volume in response to changes in water content is usually described by the soil shrinkage characteristic cur

Representative Elementary Length to Measure Soil Mass Attenuation Coefficient

With increasing demand for better yield in agricultural areas, soil physical property representative measurements are more and more essential. Nuclear techniques such as computerized tomography (CT) and gamma-ray attenuation (GAT) have been widely employed with this purpose. The

ated with soil type, vadose zone flow and transport processes are also affected by such external factors as tillage Vadose zone flow and transport processes are known to be strongly practices. For example, Petersen et al. (1999, 2001) affected by both soil structure and soil text
