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

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...

The type of tillage in arable soils affects porosity of the soil and in consequence the hydraulic conductivity. The accessibility and mobility of organic carbon in arable soils can differ depending on...
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...
Soil tensile strength as affected by time, water content and bulk density
soil tensile strength Brazilian test age-hardening
2008/11/11
We investigated the effect of soil water conditions and soil compaction on the age-hardening process of loamy sand and silty loamy sand in relation to the tensile strength. Soil samples from Germany (...
Changes of nitrogen assimilation and intracellular fluid pH in plants of barley depending on bulk density of compacted soils
soil compaction soil bulk density nutrients nitrogen assimilation cellular fluid pH
2010/1/12
The penetration resistance of different arable soils is quite different depending on the Estonian area. We are briefly introducing the results of our research on soil compaction, penetration resistanc...
Evaluation of Methods for Determination of Bulk Density of Eight Kinds of Forage under Air-dry and Wet Conditions
Forage Dry Bulk Density Wet Bulk Density Ruminants
2016/4/13
The conditions of measurement for the determination of bulk density were evaluated to assess the bulkiness of 8 kinds of forage. The bulkiness of the forages was determined with 4 different sizes of f...
