Pedotransfer Functions for Estimating Soil Bulk Density Using Image Analysis of Soil Structure [PDF]

open access: yesSensors, 2023
Soil bulk density is one of the most important soil properties. When bulk density cannot be measured by direct laboratory methods, prediction methods are used, e.g., pedotransfer functions (PTFs).

Machine-Learning Classification of Soil Bulk Density in Salt Marsh Environments [PDF]

open access: yesSensors, 2021
Remotely sensed data from both in situ and satellite platforms in visible, near-infrared, and shortwave infrared (VNIR–SWIR, 400–2500 nm) regions have been widely used to characterize and model soil properties in a direct, cost-effective, and rapid ...

Pedotransfer functions for Irish soils – estimation of bulk density (ρb) per horizon type [PDF]

open access: yesSOIL, 2016
Soil bulk density is a key property in defining soil characteristics. It describes the packing structure of the soil and is also essential for the measurement of soil carbon stock and nutrient assessment. In many older surveys this property was neglected

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

open access: yesJournal 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.

Estimating soil bulk density with information metrics of soil texture [PDF]

open access: yesGeoderma, 2017
Abstract Using the Shannon Information Entropy (IE) as a soil structure metric is proposed to analyze the effect of the particle size distribution (PSD) heterogeneity on soil bulk density values. A data base including 6239 soil samples from Florida is used.

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.

Effects of Corn Straw Biochar, Soil Bulk Density and Soil Water Content on Thermal Properties of a Light Sierozem Soil [PDF]

open access: yesNature Environment and Pollution Technology, 2023
This research aimed to quantify the effects of biochar derived from corn straw on soil thermal conductivity, capacity, and diffusivity. Firstly, the amount of biochar application (w/w) added to light sierozem soil was 0% to 5%, and the mixtures were ...

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

open access: yesE3S 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]

open access: yesJournal 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

Bulk density of forested mineral soils. [PDF]

open access: yesSilva Fennica, 1994
Relationships between bulk density and organic matter (OM) content, textural properties and depth are described for forested mineral soils from Central and Northern Finland. Core samples were taken of 0â5, 30â35 and 60â65 cm layers at 75 plots. Three measures of bulk density were calculated: the bulk density of the < 20 mm fraction (BD), the bulk ...
