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

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

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

Bulk density of forested mineral soils. [PDF]
Silva 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 ...
