Calculating particle density, bulk density, and total porosity of soil based on its texture
Soil Science Annual, 2014 This paper provides the verification of coefficients for the calculation of particle density, bulk density, and total porosity based on the texture of soils proposed by Brogowski (1990).

A digital rock physics approach to effective and total porosity for complex carbonates: pore-typing and applications to electrical conductivity [PDF]
E3S Web of Conferences, 2019 Recent advances in micro-CT techniques allow imaging heterogeneous carbonates at multiple scales and including voxel-wise registration of images at different resolution or in different saturation states. This enables characterising such carbonates at the

Experimental Study on Sensitivity of Porosity to Pressure and Particle Size in Loose Coal Media
Energies, 2018 A new experimental method for characterizing the porosity of loose media subjected to overburden pressure is proposed based on the functional relationships between porosity, true density, and bulk density.

A NEW METHOD FOR MEASURING TOTAL POROSITY IN HORTICULTURAL SUBSTRATES [PDF]
HortScience, 1990 The determination of air and water holding capacities of horticultural substrates has been plagued by errors in measurement. The amount of air and water held at container capacity is influenced by the substrate and container height. Container capacity can be established through specific measurement.

10-Years Studies of the Soil Physical Condition after One-Time Biochar Application
Agronomy, 2020 The ten-year experiment on the soil physical properties of biochar-amended Podzol was studied. Biochar was applied to the soil in the following rates: treatment BC10—10 Mg × ha−1, treatment BC20—20 Mg × ha−1, treatment BC30—30 Mg × ha−1 and treatment BC0—

Impact of selected waste applications on soil compaction
Agronomy Science, 2019 In the years 2014–2017, a field experiment was carried out, in which two types of waste were applied to soil. One of them was mineral waste – carboniferous rock from a hard coal mine, and the other – organic waste – post-fermentation sludge from ...
