Least limiting water range and degree of compactness of soils under no- tillage
Bioscience Journal, 2015 The least limiting water range (LLWR) and degree of compactness (DC) can be useful indicators of soil physical quality and crop yield. This study focused on assessing of LLWR, DC and evaluation of critical values to crop growth of an Alfisol and Oxisol ...

Remote Sensing in Ecology and Conservation, EarlyView.Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Extraction Kinetics and Molecular Size Fractionation of Humic Substances From Two Brazilian Soils
Journal of the Brazilian Chemical Society, 1999 In the present study, the extraction behaviour of humic substances (HS) from an Oxisol and a Mollisol from South Brazil, by using 0.1 and 0.5 mol L-1 NaOH and 0.15 mol L-1 neutral pyrophosphate solutions, respectively, was systematically studied.

Adsorption of P and forms of iron in no-tillage areas in the ‘Cerrado’ biome
Acta Scientiarum. Agronomy, 2014 The objective of this study was to evaluate the forms of iron extracted as sodium dithionite-citrate-bicarbonate (Fed), acid ammonium oxalate (Feo) and sodium pyrophosphate (Fep) and the relationship between these variables and the total organic carbon ...

Plant Biology, EarlyView.Meloidogyne incognita impairs eggplant growth through gall formation with changes in root cell wall components and vascular tissue disruption, while the biocontrol agent Purpureocillium lilacinum mitigates these effects by reducing nematode infection. Abstract Meloidogyne spp. induce structural changes during the development of root‐knot galls, leading

Mulching does not improve seedling survival or growth during early forest restoration
Restoration Ecology, EarlyView.Abstract Introduction Weed control is one of the main operational challenges and cost components of tropical forest restoration in former pasturelands. Physical barriers (mulches) have been proposed as an alternative to conventional ring weeding because they can suppress competing vegetation while potentially improving the soil microenvironment ...
