Horizontal alignment and cross section characteristics of a skid trail in a ground-based skidding system including curves, wheel ruts and cross slope can impact on the forest soil. In this study the m...
One peculiar feature of the inland valleys abundant in West Africa is their site-specific hydrology, underlain mainly by the prevailing landforms and topography. Development and management of these la...
Changes of selected soil physical properties (porosity P, soil organic matter SOM, bulk density ρd, particle density ρz , characteristics of water retention capacity – maximum capillary water capac...
The area devoted to growing tobacco (Nicotiana tabacum L.) in the province of Granma, Cuba, accounted for nearly 2600 ha in the year 1997, which represented the 4% of the total tobacco plantation area...
Long-term experiments can be used to assess management induced changes in soil properties and sustainability of the management system in terms of the productivity. Such data are scanty, especially in ...
A study was conducted in 2005 and 2006 to evaluate the effect of different types of crop residue mulch on soil physical properties and rice yield. The crop residue treatments were dry rice straw, bur...
The application of different soil cultivation methods before sowing increased the values of investigated physical soil properties when simultaneously the depth of cultivation and soil compaction were ...
A field and laboratory experiment was conducted during 2000-2001 and 2001-2002 to estimate the tillage and mulch effects on physical properties of soil. The experiment was laid out in split-plot desig...
Tillage is an operation to improve soil conditions for optimal crop emergence and yield. Different tillage implements and operational variables may affect soil physical properties. An experiment with ...
abstract50 cm increased and the slaking resistance decreased on those plots. The other soil structural properties determined were not significantly affected. The reason behind these unexpected finding...
The aim of this research was to determine in 2006 and 2007 the effects of different tillage systems on the soil physical properties: bulk density, water content and stability. Analyses of physical pro...
The long-term use of heavy-weight agricultural machinery has caused extensive and lasting phenomena of degradation, especially in the basic layer of soil. The influence of soil compaction by heavy tra...
