TILLAGE IMPLEMENT EFFECTS ON WET STICKY SOIL PUBLISHED

Soni Sisbudi HARSONO
The objective of the research is to reduce soil adhesion on soil tillage tools using different enamel coated through analysing soil adhesion phenomena on shear stress of tillage implement. The friction angle was found not to be related to density over the range considered. As the soil approaches saturation, part of the normal stress was moved by pore pressure so the pressure between interface particles and the surface materials decreases, which cause the friction falls. The component of adhesion entirely due to the soil water present at the interface and was thus dependent of speed of movement because of the time required for water to move to the interface. The tillage implement which are coated with a ceramic surface tends to produce a smaller soil adhesion component compare with nylatron and metal surfaces
