Simulating water distribution patterns for fixed spray plate sprinkler using the ballistic theory
ballistic model center-pivot kinetic energy losses
2014/10/28
Ballistic simulation of the spray sprinkler for self-propelled irrigation machines requires the incorporation of the effect of the jet impact with the deflecting plate. The kinetic energy losses produ...
Time-dependent changes in distribution patterns of soil bulk density and penetration resistance in a rangeland under overgrazing
Bulk density overgrazing penetration resistance rangeland soil compaction spatial variability
2011/3/29
High soil bulk density and penetration resistance as an indication of soil compaction affect soil infiltration and
runoff. Overgrazed rangelands are under severe erosion risk because of soil compacti...
