Time-dependent changes in distribution patterns of soil bulk density and penetration resistance in a rangeland under overgrazing
Bulk density overgrazing penetration resistance
2011/6/29
High soil bulk density and penetration resistance as an indication of soil compaction affect soil infiltration and runoff.
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...

Effect of organic carbon content on the compactibility and penetration resistance of two soils formed from loess
soil compactibility Corg. content penetration resistance bulk density
2008/11/21
Penetration resistance and bulk density were measured in the laboratory for two soils: grey-brown and brown, both formed from loess with different Corg. content which had been compacted using the Proc...
Effect of penetration resistance, bulk density and moisture content of soil on selected yield components of winter triticale in relation to method of cultivation
penetration resistance moisture soil bulk density yield components
2008/11/20
The influence of penetration resistance, bulk density and moisture content of soil on winter triticale crop yield was investigated. The crops were grown on land that had not been cultivated for severa...

penetration resistance moisture soil bulk density yield components
2008/11/18
The influence of bulk density, penetration resistance and moisture content in the upper layers of soil profile (0-25 cm) on variability of yield components of four winter wheat cultivars was studied. ...
PENETRATION RESISTANCE OF SOIL ON THE YEAR-LONG USING MOUNTAIN PASTURE BY THE CATTLE
penetration resistance mountain pasture system of breeding sucker beef
2010/12/6
In the year 2006 we investigated mechanical compaction of soil on the mountain pasture (altitude 920 m). Penetration resistance was researched on the compacted places, by cattle hoofs (breed Charolais...
