(IF 1.6) Pub Date : 2022-11-24 Thiago Augusto Mendes, Sávio Aparecido dos Santos Pereira, Weber Anselmo dos Ramos Souza, Juan Félix Rodríguez Rebolledo, Gilson de Farias Neves Gitirana Junior, Maurício Martines Sales, Marta Pereira da Luz
Context: Tropical soils have complex hydromechanical behaviour compared to ordinary soils and are often found in regions with well-defined wet and dry seasons. The analysis of the interaction between the soil and the atmosphere comprises understanding of multiple phenomena, such as infiltration and runoff. Unfortunately, the dynamics of soil–atmosphere interaction are commonly modelled at the watershed

A simple incubation test for determining soil dispersion and gypsum rates Soil Res. (IF 1.6) Pub Date : 2022-11-25 Xueying Liang, Pichu Rengasamy, Edward Scott, Luke M. Mosley
Context: High levels of exchangeable sodium or potassium in soils can lead to issues such as dispersion and deterioration of soil structure, reduced hydraulic conductivity and inadequate aeration. Gypsum is the most common soil amendment used to treat these issues but current methods to determine application rates (e.g. based on exchangeable sodium percentage or addition of dissolved calcium to diluted

Multivariate analysis of hydropedologically significant soil variables on cultivated semi-arid hillslopes Soil Res. (IF 1.6) Pub Date : 2022-11-21 Seval Sünal Kavakligil, Sabit Ersahin
Context: Hydropedology bridges hydrology to pedology, and hillslope hydropedology is central in understanding topography–hydropedology interrelations. Aim: The objective of this study was to statistically evaluate soil–hillslope hydropedology interrelations by multivariate analysis of hydropedologically significant soil variables (HSSVs). Methods: A complete randomised 6 × 5 × 3 factorial experiment

Plants and redox potential: iron-rich clay minerals as redox active compounds in soils Soil Res. (IF 1.6) Pub Date : 2022-11-22 Marion Bruneau, Jocelyne Brendlé, Sylvain Pluchon, Mustapha Arkoun
Redox potential is an important soil property for plant growth, nutrition and development that is still not widely considered by agronomists, even though many studies have found that cultivated soils tend to oxidise over time and the soil redox potential becomes non-optimal for plant development. The objective of this literature review is to identify a type of material that can be used as amendment

Structuring of the epigeal fauna in restoration of Brazilian semiarid forest in the short term Soil Res. (IF 1.6) Pub Date : 2022-11-04 Juvenal Martins Gomes, Wilbert Valkinir Cabreira, Sandra Santana de Lima, Rodrigo Camara de Souza, Raissa Nascimento dos Santos, Ana Licia Patriota Feliciano, Luiz Carlos Marangon, Marcos Gervasio Pereira
Context: The Caatinga biome, located in the Brazilian semiarid region, has few remnants of riparian forest. Thus, it is essential to know the effectiveness of strategies aimed at forest recovery. Aims: The objective of this study was to investigate the use of the epigeal fauna as a bioindicator tool of soil quality and ecosystem sustainability to determine the best native forest restoration strategy
