Earth System - Enviromental Sciences series

open access: yes, 2021
This book presents an in-depth guide to the subject matter and main points of hydrostructural pedology, as theorized for the first time. The authors focus on the underlying concepts, the purpose and role this field plays within agroenvironmental sciences.

Modeling the soil system : bridging the gap between pedology and soil-water physics

open access: yes, 2009
The biological and geochemical processes in soil such as organic matter mineralization, microbiological activity, and plant alimentation can be accurately assessed and modeled only with the knowledge of the thermodynamic status of the soil medium where ...

Soil Structure Under Irrigated Beans And Different Soil Management Practices [estrutura Do Solo Sob Feijão Irrigado E Diferentes Manejo Do Solo]

open access: yes, 2016
Agricultural management affects soil structure, modifying soil physical properties and soil water movement. The objective of this study was to evaluate the effects of no-tillage (NT) and conventional tillage (CT) on soil structure through physical ...

Variability in soil shrinkage along forest and pasture toposequences in Amazonia

open access: yes, 2019
Physically fragile soils are subjected to rapid and abrupt land-use changes in many tropical countries. In this respect, it is important to characterize the changes in soil structure as an essential driver of soil functioning.

Investigations of hydrostructural processes in the soil medium

open access: yes, 2014
Food security and water security are among the main global challenges. These challenges are more profound in arid and hyper-arid countries which are seeking to maximize their local food production under harsh environment, limited water resources and ...

Modeling Soil Water Movement in Pedostructure

open access: yes2006 Portland, Oregon, July 9-12, 2006, 2006
Accurate representation of the top soil matrix with special attention to the scales present is important to the dynamics of water flow and to the fate of pollution at field, farm and watershed scales. This is also important from an agronomic stand point since agriculture is the main source of pollution at a time when many agronomic models still use ...

Development and Evaluation of Functional Soil Mapping Unit Using Pedostructure Hierarchy Concept

open access: yes2007 Minneapolis, Minnesota, June 17-20, 2007, 2007
Accurate soil characterization is crucial for understanding soil-water interactions and allowing for better on-farm agricultural and environmental management. Current soil characterization methods lack quantitative attributes that integrate the soil mapping units with environmental and agronomical models.

Soil Water: Functions in Pedostructure

open access: yes, 2007
There are several models of soil water that consider the soil medium as an active site for chemical, physical, and biological processes with a bimodal porous medium, micro- and macropore systems. Few of these models consider the soil medium as a structured medium with aggregates.

Field evaluation of the pedostructure-based model (Kamel®)

Computers and Electronics in Agriculture, 2012
This study involves a field evaluation of the pedostructure-based model Kamel(R) and comparisons between Kamel(R) and the Hydrus-1D(R) model. Both models are commonly named 1D - soil water models because they simulate the flux of water within the soil, related to climate conditions variation and water uptake by roots.
