Soil bulk density assessment in Europe

open access: yesAgriculture, Ecosystems & Environment
The topsoil Land Use and Cover Area frame Statistical survey (LUCAS) aims at collecting harmonised data about the state of soil health over the extent of European Union (EU). In the LUCAS 2018 survey, bulk density has been analysed for three depths, i.e., 0-10 cm = 6140 sites; 10-20 cm = 5684 sites and 20-30 cm =139 sites.

Quantification of C and N stocks in grassland topsoils in a Dutch region dominated by dairy farming [PDF]

open access: yes
Estimates on soil organic carbon (SOC) and nitrogen (N) stocks in soils cannot be directly calculated from routine soil analyses, since these often lack measurements on soil bulk density (Bd).

Impact of mechanized harvesting on compaction of sandy and clayey forest soils : results of a meta-analysis [PDF]

open access: yes, 2012
Nowadays, harvest operations are predominantly performed fully mechanized using heavy tractors or forestry machines. The resulting soil compaction may negatively affect the soil ecosystem.

Bulk soil properties as determinants of the compression strength of puddled lowland paddy soils in Sri Lanka

open access: yesTropical Agricultural Research, 2015
Soil strength/penetration resistance of lowland puddled soil is an important parameter for designing farm machinery. This study was aimed to estimate the overall penetration resistance of lowland puddled soils through the assessment of bulk soil ...

Effects of tillage on soil physical properties and root growth of maize in loam and clay in central China

open access: yesPlant, Soil and Environment, 2013
Subsoil compaction can result in unfavourable soil physical conditions and hinder the root growth of maize. The effects of deep tillage and conventional tillage on soil physical properties and root growth of maize were studied during 2010-2011 at two ...

Structure of clay topsoil affected by tillage intensity [PDF]

open access: yes, 2006
On the clay loam soil in 0-0,05 m layer, the average dry bulk density of ploughed soil was greater than that of reduced tilled soils. This was probably due to the higher organic matter content of reduced tilled plots. On the clay soil, the differences in

Energy in Clod-Size Reduction of Vibratory Tillage [PDF]

open access: yes, 1969
The objective of mechanical manipulation of the soil (tillage) in production of agricultural crops is to produce soil conditions and environment favorable to crop growth by changing bulk density, soil-aggregate size distribution and other characteristics

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Physical characteristics of soil under different cropping and natural system on the plain of jars, Xieng Khouang province, Laos [PDF]

open access: yes, 2006
Conservation agriculture and direct seeding mulch-based cropping (DMC) systems greatly modify plant and soil interaction. Plants commonly provide energy that fuels biological processes and either directly or indirectly creates structure within soils ...
