“…According to references, the error due to the variation in the temperature during the extraction could be considered to be slight. The amount of ion exchange resin has a direct effect on the extraction results (ACQUAYE et al 1972). The handling of the resin is difficult, because the resin is wet.…”

The aim of the study was to determine the plant-available manganese in the soil and to study which factors regulate the plant-available manganese. The material consisted of 193 mineral soils and 17 organogenic soils. Oats (Avena saliva L.), Italian ryegrass (Lolium multiflorum Lam.) and turnip rape (Brassica campestris oleifera L.) were used as the test plants in the pot experiments. A cation exchange resin method was developed for extracting soil manganese. The method enabled both exchangeable and reducible manganese to be determined. Exchangeable manganese comprised the manganese which was freely present in the soil solution in cationic form, and the manganese in cationic form which could be exchanged from the soil. Reducible manganese was the manganese reducible to the oxidation state, Mn2+, by the action of hydroquinone, hydroxylammonium chloride or ascorbic acid. The content of exchangeable manganese in the soil explained 33,7 % of the variation in the manganese content of the first yield of ryegrass. The greater the number of yields harvested, the smaller was the significance of the content of exchangeable manganese in the soil as an independent variable. On the other hand, when the content of reducible manganese in the soil was used as the independent variable, then the greater the number of yields harvested, the better it explained the variation in the manganese content of the yield. The content of manganese reduced by hydroxylammonium chloride explained 68,6 % of the variation in the manganese content of the fourth yield. The contents of exchangeable manganese and manganese reducible by ascorbic acid explained 73,4 % of the variation in the manganese content of the roots. The pH, the organic carbon content and the content of hydroquinone-reducible manganese in the soil explained 67,0 % of the variation in the content of exchangeable manganese in the plough layer of the mineral soils. The content of "total" manganese in the plough layer of the mineral soils explained 27,6 % of the variation in the content of ascorbic acid-reducible manganese. The plant stands increased the content of exchangeable manganese in the soil and decreased the redox potential of the soil in comparison to the incubated soils. The content of exchangeable manganese started to increase when the redox potential of the soil fell below 0,59 V. Adding glucose promoted the reduction of manganese in the soil, reduction appearing to be both biological and non-biological in origin. Soil moisture increased the content of exchangeable manganese when the moisture was higher than the field capacity. Liming decreased the content of exchangeable manganese in the soil more than would have been expected on the basis of the change in pH values. The manganese content and manganese uptake of the crop were also reduced. Adding large amounts of manganese (Mn 51,5 kg/ha*20 cm) did not prevent liming (calcite 14 t/ha*20cm) from reducing the manganese content of the yield.

Harold F. Walton joined the staff of the University of Colorado in 1947. His research interests in ion exchange date from 1938 when he went to work for the Permutit Co. as a research chemist; from there he went to Northwestern University in 1940. He obtained the BA and DPhil degrees at Oxford University. He Is the author of three textbooks on inorganic and analytical chemistry and coauthor with William Rieman III of "Ion Exchange in Analytical Chemistry" published in 1970. He has contributed chapters on the physical and analytical chemistry of ion exchange to several cooperative works. In 1961 he was chairman of the Gordon Research Conference on Ion Exchange. Dr. Walton spent the 1966-67 academic year and half of 1970 as a Fulbright visiting professor at the University of Trujillo, Peru. He Is a member of the Advisory Board of Analytical Chemistry.has chapters on ion exchange in nonaqueous and mixed solvents by Marcus, on ligand-exchange chromatography by Walton, and on liquid ion exchange technology by Kunin; Volume 5 has accounts of inorganic ion exchangers by Clearfield, Nancollas, and Blessing; of ion exchange in elemental analysis by Strelow; and on pellicular ion exchange resins by Horvath. A good short account of ion exchange in analytical chemistry is that by Inczedy in the Chemical Rubber Publishing Company's review series (A6). The International Union of Pure and Applied Chemistry has published the report of a committee on ion-exchange nomenclature, consisting of O. Samuelson, E. Bayer, and F. G. Helfferich (A7).In the Russian language, two books on ion exchange have appeared (A9, A 28). Both books were reviewed in the Russian Journal of Analytical Chemistry (Zh. Anal. Khim.). Another significant Russian book is that edited by Sladkov (A 29), which has a chapter by Davankov, Rogozhin, and Semechkin on ligand-exchange chromatography and another by Rogozhin, Davankov, and Peslayakas on the chromatographic separation of optical isomers. Reviews on chelating ion exchangers (A 23) and complex-ion formation in exchange resins (A27) have also appeared. A paper by Gurvich (288) describes the use of organic complexing agents incorporated into absorbants like charcoal.A German review (A20) is aptly titled "Ion Exchangers -Active Polymers." Recent progress in ion-exchange chromatography is reviewed in Japanese (A 14). An English-language book reflecting the author's own research and interest is that by Muzzarelli (A22).The latest volume of "Chromatographic Reviews," now published as an integral part of the Journal of Chromatography, includes two chapters on a very timely topic, the
