Study on Improvement of Soil Porosity [PDF]

, 2022
In order to further improve soil porosity and improve soil physical properties, the raw materials, formula and application methods of soil amendment were optimized, and the pH and porosity of yellow soil were compared and analyzed after application of soil amendment.

The Porosity of Soil Aggregates From Bulk Soil and From Soil Adhering to Roots

Plant and Soil, 1985
Total porosity and pore-size distribution (p.s.d.) were determined in soil aggregates taken in plots planted with maize and treated with farmyard manure and three rates of compost. Soil aggregates were collected from the soil adherent to the maize roots (root soil aggregates) and from bulk soil (bulk soil aggregates).

Double-Porosity in Soil [PDF]

, 2023
This image shows inter-aggregate and intra-aggregate pores, one of the double-porosity phenomena that may exist in soil. Double-porosity occurs in soil when two sets of porosities having highly contrasting hydraulic properties co-exists in the fabric of ...

Machinery’s impact on forest soil porosity

Journal of Terramechanics, 2020
The heavy machines used in forest operations not only cause reduction of the total amount of soil pores but also drastically modify their size distribution. The effects in these terms of repeated passages of a tracked skidder and a wheeled one of quite similar size were evaluated in a forest of central Italy.

Analysis of porosity in a tilled “crusting soil” in Zimbabwe

Geoderma, 1993
Abstract Samples were collected in a tilled “crusting soil” from zones with different structures and their porosity was analysed with mercury porosimetry. The results showed three types of elementary pore volumes that differ in both the size and origin of the pores.

Organic carbon and soil porosity

Australian Journal of Soil Research, 2003
The %C within the top sandy 0.15 m of a sodic Hydrosol under native trees consisted of a constant %C in uncharged organic matter and a %C in negatively charged organic matter decreasing linearly with depth, as did the specific volume of the soil. The kaolinitic clay present was strongly bonded together.
