A Framework for Soil-Water Modeling Using the Pedostructure and Structural Representative Elementary Volume (SREV) Concepts

open access: yesFrontiers in Environmental Science, 2014
Current soil water models do not take into account the internal organization of the soil medium and consequently ignore the physical interaction between the water film at the surface of solids that form the soil structure and the structure itself.

Bioremediation of Oil Contaminated Soils by Washing under Static Conditions [PDF]

open access: yesIranica Journal of Energy and Environment, 2019
In this research five different solutions were used to wash an oil contaminated soil with the initial TPH (Total Petroleum Hydrocarbon) content of 46 g kg-1 (grams of TPH per kg of dry soil).

Short- and Long-Term Effects of Lime and Gypsum Applications on Acid Soils in a Water-Limited Environment: 2. Soil Chemical Properties

open access: yesAgronomy, 2020
Soil acidity or aluminum (Al) toxicity is a major limitation to crop production. In this paper, we examine the effects of surface-applied lime and gypsum on soil profile chemical properties that affect Al toxicity in short-term (1 year), medium-term (2 ...

Spatial pattern consistency and repeatability of proximal soil sensor data for digital soil mapping

open access: yes, 2023
Data from proximal soil sensors can facilitate digital soil mapping at high spatial resolutions. However, their use for predicting static soil properties, such as texture, is affected by spatio-temporal changes in environmental and measurement conditions.

Soil Test Phosphorus Recovery from Livestock Manures Compared with Inorganic Fertilizer in Soil Incubations

open access: yesApplied and Environmental Soil Science, 2010
This paper compared dairy and hen manure P recovery relative to fertilizer P recovery for two Nova Scotia soils with different antecedent soil test P (STP), incubated for 5, 15, 30, 60, and 110 days.

Physics of the Soil Medium OrganizationPart 1: Thermodynamic Formulation of the Pedostructure Water Retention and Shrinkage Curves

open access: yesFrontiers in Environmental Science, 2014
The equations used in soil physics to characterize the hydro-physical properties of the soil medium cannot be other than empirical since they do not take into account the multi-scale functional organization of the soil medium that is described in ...

Soil microbial improvement using enriched vinasse as a new abundant waste

open access: yesScientific Reports, 2023
This study proposes the use of vinasse, an inexpensive and readily available waste biopolymer, as a fundamental component of a waste culture medium that can enhance the effectiveness and cost-efficiency of the microbial-induced calcite precipitation ...
