The Influence of Using Soil Particles Percentage in Comparison with Geometric Characteristics of Soil Particles on the Accuracy of the Pedotransfer Equations and the Critical Point of SWRC

علوم آب و خاک, 2019
Soil water retention curve (SWRC) reflects different states of soil moisture and describes quantitative characteristics of the unsaturated parts of the soil. Direct measurement of SWRC is time-consuming, difficult and costly.

Estimation of water retention in Oxisols cultivated with cotton plant in the cerrado of Mato Grosso = Estimativa da retenção de água em Latossolos do Cerrado mato-grossense cultivados com algodão

Agro@mbiente On-line, 2014
In the state of Mato Grosso, the area planted with cotton is mainly concentrated in the plains, where the climate Aw determines an alternation between a rainy and a dry season, and where the soil is predominant Red-Yellow Latosol and Red Latosol (Oxisol).

Correction of resistance to penetration by pedofunctions and a reference soil water content

Revista Brasileira de Ciência do Solo, 2012
The soil penetration resistance is an important indicator of soil compaction and is strongly influenced by soil water content. The objective of this study was to develop mathematical models to normalize soil penetration resistance (SPR), using a ...

Funções de pedo-transferência para a curva de retenção da água no solo Pedotransfer functions for the soil water retention curve

Revista de Ciências Agrárias, 2009
As funções de pedo-transferência (PTFs) permitem estimar propriedades hidrodinâmicas do solo a partir das suas propriedades básicas. Neste estudo desenvolveram-se PTFs para a determinação de pontos específicos da curva de retenção da água no solo por ...

Microstructural strength of tidal soils – a rheometric approach to develop pedotransfer functions

Journal of Hydrology and Hydromechanics, 2018
Differences in soil stability, especially in visually comparable soils can occur due to microstructural processes and interactions. By investigating these microstructural processes with rheological investigations, it is possible to achieve a better ...
