Spatial variability of soil bulk density and its controlling factors in an agricultural intensive area of Chengdu Plain, Southwest China

Journal of Integrative Agriculture, 2019
Soil bulk density is a basic but important physic soil property related to soil porosity, soil moisture and hydraulic conductivity, which is crucial to soil quality assessment and land use management.

Will European soil-monitoring networks be able to detect changes in topsoil organic carbon content? [PDF]

, 2008
Within the United Nations Framework Convention on Climate Change, articles 3.3 and 3.4 stipulate that some voluntary activities leading to an additional carbon (C) sequestration in soils could be accounted as C sinks in national greenhouse gas ...

The Spatial Variability of Soil Physical Properties of Different Sized-gap in a Subtropical Forest, China

Applied Environmental Research, 2020
Gap areas create heterogeneity in the spatial environment, which is important to plant regeneration and diversity. Soil physical properties (SPP) are factors that affect plant growth. This study aims to assess the spatial variability of SPP in different

Spatial variability in the degradation rate of isoproturon in soil

Environmental Pollution, 2001
Thirty samples of soil were taken at 50-m intersections on a grid pattern over an area of 250 x 200 m within a single field with nominally uniform soil characteristics. Incubations of isoproturon (3-(4-isopropylphenyl)-1,1-dimethylurea) under standard conditions (15 degrees C; -33 kPa soil water potential) indicated considerable variation in ...

Effect of high-resolution spatial soil moisture variability on simulated runoff response using a distributed hydrologic model [PDF]

Hydrology and Earth System Sciences, 2011
The importance of spatial variability of antecedent soil moisture conditions on runoff response is widely acknowledged in hillslope hydrology. Using a distributed hydrologic model, this paper aims at investigating the effects of soil moisture spatial ...

Spatial Variability of Selected Soil Properties in Long-Term Drained and Restored Peatlands

Frontiers in Environmental Science, 2022
Drained peatlands have been rewetted for restoration in Europe and North America for about 25 years. However, information on spatial variability of soil chemical and biochemical properties in long-term drained and restored peatlands is insufficient to ...

Contribution of microbial activity and vegetation cover to the spatial distribution of soil respiration in mountains

Frontiers in Microbiology, 2023
The patterns of change in bioclimatic conditions determine the vegetation cover and soil properties along the altitudinal gradient. Together, these factors control the spatial variability of soil respiration (RS) in mountainous areas.
