Impact of forest fire ash on surface charge characteristics of andisols
(LIPPINCOTT WILLIAMS & WILKINS, 2007)
Forest fires are a common occurrence in central southern Chile where soils are mostly Andisols. The ash deposits may alter the chemical properties of the soils in the burned areas and nearby agricultural lands. In a column ...
Components of Surface Charge in Tropical Soils With Contrasting Mineralogies
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Study of surface electric charges of soil colloids helps in understanding the physicochemical phenomena that influence the capacity of retaining nutrients and their availability to plants. The structural charge (sigma(0), ...
Sorption behavior of bensulfuron-methyl on andisols and ultisols volcanic ash-derived soils: Contribution of humic fractions and mineral-organic complexes
(2009)
Bensulfuron-methyl sorption was studied in Andisol and Ultisol soils in view of their characteristic physical and chemical properties, presenting acidic pH and variable charge. Humic and fulvic acids (HA and FA) and humin ...
Metsulfuron-methyl sorption/desorption behavior on volcanic ash-derived soils. Effect of phosphate and pH
(2010)
Metsulfuron-methyl sorption/desorption behavior was studied through batch sorption experiments in three typical volcanic ash-derived soils belonging to Andisol and Ultisol orders. Their distinctive physical and chemical ...
Quantification of permanent and variable charges in reference soils of the State of Pernambuco, Brazil
(Revista Brasileira de Ciência do Solo, 2017)
Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms
(2010)
Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
Lime and gypsum combination improves crop and forage yields and estimated meat production and revenue in a variable charge tropical soil
(2019-12-01)
In tropical integrated crop-livestock under no-till (NT) systems, the surface application/reapplication of lime and/or gypsum can reduce re-acidification rate of the soil and improve plant nutrition, crop yields, and ...
