Сравнителна характеристика на хумусното състояние в Пясъчни почви от района на Българското Черноморско крайбрежие и тези от крайдунавските низини

open access: yesПочвознание, агрохимия и екология, 2015
Humus content and composition for Sand Soils (Arenosols) of Bulgarian sea coast is in direct correlation of the ages of parent materials. The ages of sea ledges and time for soil formation are in direct relationship of relief and micro relief of the ...

The Effect of Non-Plastic Fines Content on Pore Pressure Generation Rates in Cyclic Triaxial and Cyclic Direct Simple Shear Tests

open access: yesEng
When loose, saturated sands and non-plastic silts are subjected to undrained cyclic loading, they will generate positive pore pressures. This increase in pore pressures leads to a decrease in effective stress with a corresponding decrease in shear ...

Response of St. Augustinegrass to Fluridone in Irrigation Water [PDF]

open access: yes, 2003
Research has shown that aquatic weeds, particularly hydrilla ( Hydrilla verticillata , (L.F.) Royle), can be controlled with exposure of 8 to 12 weeks with concentrations of 10 to 15 ppb of fluridone (1-methyl-3-phenyl-5-[3-trifluoromethyl) phenyl]-

The Influence of short-term land use change on soil evolution in the centre-south coastal areas of Sardinia [PDF]

open access: yes, 2008
The land use change in short-term (time and space) in the Mediterranean context can be induced by phenomena like destruction of the autochthonous plant species, land abandonment, overgrazing, fire, urbanization (above all for touristic purpose), etc ...

A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops [PDF]

open access: yes, 2005
The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment.

Influence of the principal stress rotation on the undrained shear strength of silty sand [PDF]

open access: yesعلوم زمین خوارزمی
The construction of geotechnical structures in sandy soils requires load bearing evaluation in undrained conditions. Undrained shear strength depends on many factors, including principal stress rotation (anisotropic behavior). However, the effect of this
