Rind hardness in sugarcane plays a major role lodging resistance, and internode borer resistance,screening of for rind is essential reducing yield loss. In order to identify the suitability soil penetrometer rapid measurement, testing was carried out two clones different variability viz., Co 13003 (hard type) 14002 (soft type). The investigation by three methods pendulum type impact test rig, t...

The driving wheels affect the tractive efficiency, fuel consumption, and soil compaction. This study presents fatigue analysis of a spike segment that is main part an innovative designed to improve tractor performance. design improvement was proposed for Chernozem allowing full penetration spikes. loaded by forces resulting from maximum drawbar pull at 100% wheel slip penetrometer resistance. A...

[1] Measurements of snow using a high-resolution micropenetrometer can be used to discriminate between different snow types; in lower-density snow the signal is sensitive to microstructure, and micromechanical properties can be estimated. Although a physics-based snow penetration theory was first developed almost a decade ago, since that time the majority of studies using snow micropenetrometer...

Introduction: During the past planetary surface missions, few instruments have been deployed to directly assess soil physical properties like density, soil strength (internal friction and cohesion), and pressure/sinkage curves, or their spatial variation. Several Soviet lunar missions were equipped with small cone vane penetrometers, and the Apollo astronauts also used two different manual pene...
