Zinc Sorption by Acid, Calcareous and Gypsiferous Soils as Related to Soil Mineralogy
Zinc (Zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. Contradicting evidence has been reported for factors influencing Zn behavior in soils. The aim of this study was to investigate the Zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (Na+, K+ and H2PO4, NO3 and Cl backgrounds). Iso...
متن کاملIdentification of Beijerinckia from Pacific Northwest soils.
The genus Beijerinckia Derx has been described as being limited to the tropical regions and rare or nonexistent in temperate zones (M. Alexander, Introduction to Microbiology, 1961). Other workers (J. Dobereiner and A. P. Ruschel, Soil Biol. Intern. News Bull. 1:3, 1964) have expressed surprise that Beijerinckia has not been reported as found in soils in such large areas as the southern United ...
متن کاملkinetics of zinc sorption by some calcareous soils of iran
the kinetics of zn sorption by ten calcareous soils of iran were measured and fitted to several equations (zero-, first-, second-, third-order, parabolic diffusion, simple elovich, and exponential equations). two initial concentrations of zinc i.e. 20 and 80 mg zn l-1 were used and observations were carried out for 100 hours. the time required to reach the near equilibrium state was about 24 ho...

متن کاملPhosphorus Sorption by Gravels in Lateritic Soils
t The effect of sesquioxidic i i ic gravels (>2 mm size fraction) on phosphorus sorption by two gravelly lateritic soils was investigated by phosphorus sorption experiments, X-ray diffraction, ti , autoradiography and electron microscopy. In one soil the abundance and size of gravels l decreased downslope. As the gravel content of both soils increased (13-61%), ), the proportion of large (>8 mm...
