In order to establish a Discrete Element Method (DEM) model of soil particles, the in laboratory bin was used as research object. The texture determined be sandy loam by sieving, and shape particles analyzed an image particle analyzer geometric particles. Edinburgh Elasto-Plastic Adhesion (EEPA) chosen contact for simulation analysis, accuracy selection tests. parameters played crucial role res...

organic matter and its related soil properties are among the most important indicators of soil quality. despite the importance of soil organic carbon, no comprehensive study has been done on organic carbon changes in soils of the isfahan province. the objective of this research was to investigate factors affecting soil organic carbon in soils of this province. a total of 248 surface soil sample...

Existing calibration methods for contact parameters of soil discrete elements are primarily based on a single physical property (e.g., natural accumulation angle and shear characteristics). To solve this limitation, method the area difference was proposed in accordance with actual operation effect ridge furrow opener. The typical clay loam middle lower reaches Yangtze River (moisture content 20...

The unsaturated soil hydraulic properties, including soil water retention curve and hydraulic conductivity, are the crucial input parameters for simulating soil water and solute transport through the unsaturated zone at regional scales, and are expensive to measure. These properties are frequently predicted with pedotransfer functions (PTFs) using the routinely measured soil properties. 110 soi...
