Considering the soil compaction status on logging areas in a Hyrcanian forest
Journal of Forest Science, 2015 This paper deals with the issue of soil compaction during timber harvesting operations on cutting areas. Soil compaction was assessed following the logging operation in Darabkola forest area by measuring soil bulk density.

Effects of Wetting-drying Cycles on Bulk Density and Saturated Hydraulic Conductivity of Soils
Guan'gai paishui xuebao, 2022 【Objective】 Changes in density and hydraulic conductivity of soil not only modulate subsurface hydrological processes but also affect root growth and root uptake of water and nutrients from soil.

Soil compaction caused by 450C Timber Jack wheeled skidder (Shefarood forest, northern Iran)
Journal of Forest Science, 2007 In forest harvesting operations usually after using skidding machinery (skidders), traces of soil damage in the form of soil compaction and wheel and logs ruts can be seen in the forest soil. Soil bulk density, which represents soil compaction, decreases

Thin Layer Measurement of Soil Bulk Density [PDF]
Journal of Range Management, 1993 Measurement of soil bulk densities is difficult if there are gravel, stones, or other materials present in the soil profile. A technique is offered for estimating the soil bulk density in thin layers (1.0 cm) in loose, nonuniform soils with low moisture levels. The technique consists of the removal of the soil in shallow layers.

Saturated Soil Hydraulic Conductivity is not Constant But Varies with the Time It is Measured
Guan'gai paishui xuebao, 2021 【Background and objective】 Saturated soil hydraulic conductivity (KS) is an important parameter characterizing the ability of soil to conduct water. It is often assumed to depend on soil structure and is hence constant for a given soil.

Bulk Densities of Brazilian Amazon Soils Related to Other Soil Properties
Soil Science Society of America Journal, 1998 Abstract The results of this study provide the first baseline for predicting D b from soil properties for soils across the Amazon basin. Bulk density values are needed to convert nutrient content and organic carbon (OC) content to weight of nutrient and ...

Deriving regional pedotransfer functions to estimate soil bulk density in Austria
Die Bodenkultur, 2021 Soil bulk density is a required variable for quantifying stocks of elements in soils and is therefore instrumental for the evaluation of land-use related climate change mitigation measures. Our motivation was to derive a set of pedotransfer functions for
