Study on Soil Erosion Law of Highway Spoil Ground [PDF]

E3S Web of Conferences, 2020
In this study, a typical spoil ground was selected in the test area, and runoff plots were set up. Through rainfall tests and statistical analysis of the data, the soil erosion law of the spoil ground was studied.

The effects of forward speed and depth of conservation tillage on soil bulk density [PDF]

Journal of Agricultural Machinery, 2015
Introduction: In recent years, production techniques and equipment have been developed for conservation of tillage systems that have been adopted by many farmers. With proper management, overall yield averages for conventional and reduced tillage systems

Stratified Data Reconstruction and Spatial Pattern Analyses of Soil Bulk Density in the Northern Grasslands of China

ISPRS International Journal of Geo-Information, 2020
The spatial pattern of soil bulk density in the grasslands of northern China largely remains undefined, which raised uncertainty in understanding and modeling various soil processes in large spatial scale.

Modeling the Impact of Rhizosphere Bulk Density and Mucilage Gradients on Root Water Uptake

Frontiers in Agronomy, 2021
In models of water flow in soil and roots, differences in the soil hydraulic properties of the rhizosphere and the bulk soil are usually neglected. There is, however, strong experimental evidence that rhizosphere and bulk soil hydraulic properties differ

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.

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.

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.
