Soil Structure under Forest and Pasture Land-Uses Affecting Compressive Behavior and Air Permeability in a Subtropical Soil

Soil Systems, 2022
Machinery traffic and animal trampling can deform the soil and, consequently, impair soil pore functioning. This study aimed to evaluate how soil structure affects the compressibility, physical properties and air permeability of a Typic Paleudalf under ...

Predicting soil bulk density for incomplete databases

Geoderma, 2014
Abstract Soil bulk density (ρb) is important because of its direct effect on soil properties (e.g., porosity, soil moisture availability) and crop yield. Additionally, ρb measurements are needed to express soil organic carbon (SOC) and other nutrient stocks on an area basis (kg ha− 1).

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

SOIL, 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

Soil-Surface-Image-Feature-Based Rapid Prediction of Soil Water Content and Bulk Density Using a Deep Neural Network

Applied Sciences, 2023
This study aimed to develop a deep neural network model for predicting the soil water content and bulk density of soil based on features extracted from in situ soil surface images. Soil surface images were acquired using a Canon EOS 100d camera.

Soil resistance and bulk density under different tillage system

Poljoprivreda, 2020
A stationary field experiment of a reduced soil tillage was implemented at a Hypogley (Hypogleyic soils A–Gso–Gr soil horizon sequence) soil type of Eastern Croatia during three seasons and set up as a split-plot randomized block design in four repetitions.

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.

Using the Response Surface Methodology to Predict the Effect of Different Moisture Levels on the Bulk Density and Penetration Resistance of Soil Under Different Operating Conditions [PDF]

Journal of Agricultural Machinery
Soil properties play a fundamental role in the success of agricultural operations through their impact on crop growth and quality, as they determine their ability to retain water and absorb nutrients, and affect soil aeration and the root system. The aim

Vibration-induced conductivity fluctuation measurement for soil bulk density analysis [PDF]

SPIE Proceedings, 2007
Soil bulk density is a physical property of soils that affects water storage, water and nutrient movement, and plant root activity in the soil profile. The ability to quantify soil bulk density using vibration-induced conductivity fluctuation was investigated with possible field applications in the future.

SOIL BULK DENSITY AS RELATED TO SOIL PARTICLE SIZE DISTRIBUTION AND ORGANIC MATTER CONTENT [PDF]

Poljoprivreda, 2003
Soil bulk density is a dynamic property that varies with the soil structural conditions. The relationships between some soil physical and chemical properties such as, clay content (C), silt content (Si), sand content (S), very fine sand content (Vfs ...
