Microelements in Soils of Israel

Selenium in soil, plant, and animal systems

“…Like phosphate fixation, they concluded, in soils the selenites and selenates can be absorbed on CaCO 3 particles or can form certain insoluble complexes in combination with some divalent cations like Ca ++ or Ba ++ . In fact, their findings were supported by Ravikovitch and Margolin, 49 who recommended the use of BaCl 2 to decrease the availability of Se to plants in highly seleniferous soils, with the assumption that the soluble selenites can be changed to sparingly soluble barium selenites.…”

Iodine, bromine and chlorine contents in solls and plants of Japan

“…This applies to the conte nt of iodine, bromine and chlorine in the humus layer of forest soils in Norway (43), the bromine content of humic volcanic ash soils in Japan (18), the contents of Downloaded by [University of Glasgow] at 05:52 20 December 2014 iodine and bromine in Russian soil, particularly peat soil (38), the iodine in soils in England (41), and so on. On the other hand, the content of iodine in soils in Israel (42) and in New Jersey, U.S.A. (40) have been reported not to show any correlation with the content of soil organic matter, which is ascribed to the low organic matter content of these soils. No correlation was found between cIay content and any of the 3 elements in either soils, but the content of the 3 elements was particularly low in sandy soil with little clay.…”

“…80 ppm was found in peat bog in addition to the case (37) of salt-accumulation in a soil derived from parent rock with high content of iodine (sedimentary rock) in the Central Baraba region of Western Siberia in which more than 300 ppm of iodine had been accumulated. The average content for each soil type or region was at most 20 ppm for the peat bog and only several ppm for the other soil types or areas (38)(39)(40)(41)(42)(43)(44). In other words, values as high as those obtained in the soils of the basin of the Miomote River have not been reported.…”

Proceedings of the 1990 Billings land reclamation symposium on Selenium in arid and semiarid environments, Western United States

“…Several exceptions include an early study by Byers and others (1938) that reports a maximum concentration of 7 ppm selenium in alfalfa from southeastern Colorado. A second exception is a report of up to 44 ppm selenium in alfalfa grown in Israel (Ravikovitch and Margolin, 1957). We also have a record (Oscar Olson, South Dakota State University, written commun., 1975) of an alfalfa sample that contained 27.3 ppm selenium.…”
