“…The pool measured by resin extraction is very similar to that assessed with isotopic dilution (Amer et al 1955). Sibbesen (1978) and Naidu et al (1991) reported that resins (HCO 3 and Cl forms, respectively) better predicted the amount of plant-available P than the 32 P isotope dilution method. Tran et al (1992) confirmed that resins in both HCO 3 and Cl forms had better correlation with crop P uptake than 32 P isotopic exchange in all the acidic, neutral and calcareous soils tested.…”

Qian, P. and Schoenau, J. J. 2002. Practical applications of ion exchange resins in agricultural and environmental soil research. Can. J. Soil Sci. 82: 9-21. The use of synthetic ion-exchange resins to examine ion bioavailability in soil and sediment systems has attracted much attention over the years. The first report in this regard was made 7-8 yr after resins were developed in the 1930s. So far, nearly 400 journal articles have been published related to use of resins in soil and environmental studies. The experience gained has led to more widespread applications in research as well as practical use in soil fertility assessment and fertilizer recommendations. Two commercial products developed in North America have directly resulted from years of research efforts. Recent developments in resin technology and availability warrant an updated review of the literature to aid in better understanding and utilizion of this technique.In this paper we provide an overview of historic and current developments in the use of ion exchange techniques in soil research. We also provide specific examples of successful use of batch and diffusion-sensitive ion exchange techniques in research and commercial use to assess ion availability. Finally, we address certain frequently asked questions about how the ion exchange resin technique is applied and how results are interpreted, including their advantages and limitations.Key words: Ion exchange resin, agriculture, environment, soil research Qian, P. et Schoenau, J. J. 2002. Application pratique des résines échangeuses d'ions dans la recherche sur les sols cultivés et naturels. Can. J. Soil Sci. 82: 9-21. L'usage de résines échangeuses d'ions pour évaluer la biodisponibilité des ions dans le sol et les sédiments a considérablement retenu l'attention au fil des ans. Le premier rapport sur le sujet a été publié 7 ou 8 ans après la création des résines, dans les années 30. On répertorie pour l'instant près de 400 articles sur l'utilisation de telles résines dans les études sur le sol et sur l'environnement, dans les périodiques scientifiques. L'expérience aidant, les applications de ces produits en recherche et pour l'évaluation de la fertilité du sol et la formulation de recommandations se sont multipliées. De nombreuses années de recherche ont abouti à la genèse de deux produits commerciaux en Amérique du Nord. Les progrès récents de la technologie des résines et l'existence de tels produits justifient un nouveau regard sur la littérature scientifique, si l'on veut mieux comprendre et exploiter cette technique. Les auteurs tracent dans leurs grandes lignes l'historique des techniques d'échange d'ions dans la recherche sur les sols et les développements récents en la matière. Ils présentent aussi des cas spécifiques où les techniques d'échange d'ions par lot et par diffusion ont donné de bons résultats dans la recherche et le commerce pour évaluer la disponibilité des ions. Enfin, les auteurs répondent à des questions souvent posées sur les applications de la technique des résines échan...

“…A faixa de variação dos teores de P resina foi menor que a dos teores de Mehlich-1 (Quadros 2 e 3) e os valores foram significativamente correlacionados (r = 0,47, p < 0,001). Menores valores para a resina do que para o Mehlich-1 têm sido relatados com freqüência (Leal et al, 1994;Nuernberg et al, 1998) e poderiam ser explicados pelo fato de extratores químicos, como o Mehlich-1, retirarem o P lábil e parte do P não-lábil (Syers et al, 1973;, enquanto a resina extrai apenas o P lábil ou parte deste (Sibbensen, 1978;Raij et al, 1987).…”

RESUMOOs solos do semi-árido nordestino têm sido reconhecidos como deficientes em P. Todavia, a grande diversidade de ordens a que eles pertencem indica que não devem ser semelhantes quanto às concentrações das diferentes formas deste elemento. A concentração de P foi avaliada em 69 amostras de solo das dez ordens mais comuns no semi-árido, nas camadas de 0-20 e 20-40 cm. O P foi extraído pelo Mehlich-1 e por fracionamento seqüencial, por extração com resina, NaHCO 3 , NaOH e H 2 SO 4 , e por digestão peróxido/sulfúrica. O P total (somatório das frações) variou de 52 a 1.625 mg kg -1 , estando a maioria dos solos na faixa entre 100 e 200 mg kg -1 , na camada de 0-20 cm, com uma grande variabilidade entre as ordens e dentro delas. Grande variabilidade foi encontrada também para qualquer das frações. De modo geral, Neossolos Flúvicos, Vertissolos, Luvissolos e Cambissolos tiveram os maiores valores; Argissolos, Neossolos Litólicos e Latossolos, valores intermediários, e Neossolos Regolíticos, Planossolos e Neossolos Quartzarênicos, os mais baixos. O maior reservatório de P, de forma geral, foi o P residual e os menores, as frações mais lábeis (P resina e Pi-NaHCO 3 ), representando juntas entre 7 e 12 % do P total. Mehlich-1 extraiu baixas proporções de P total dos Vertissolos (1 %) e alta proporção dos Latossolos (24 %), o inverso ocorrendo com a extração com bicarbonato (11 e 5 %, respectivamente). A resina extraiu baixas proporções em todas as ordens (1 a 6 %).Termos de indexação: fracionamento, P lábil, P orgânico, P inorgânico, P residual.

Concentrations and identity of ions in the soil solution may affect soil phosphorus (P) reactions and P availability. In this study, the magnitude of these reactions was evaluated following the application of Minjingu phosphate rock (MPR) combined with chloride and carbonate salts of Na and Ca within an incubation experiment. Twenty-one days later NaOH-P and HCl-P were determined. This investigation was undertaken with the aim of identifying the role of Ca-ion activity in the liquid phase on the solubilization of MPR and formation of insoluble Ca-P phases.The increase in pH was higher with Na 2 CO 3 than with CaCO 3 , while both CaCl 2 and NaCl resulted in slight decreases in pH. The dissolution of MPR was higher overall when MPR was applied singularly than for the combined application of the phosphate rock with salts of calcium or sodium after 60 days of incubation. Dissolution of MPR decreased as levels of CaCO 3 or CaCl 2 increased but the decrease was more pronounced in CaCO 3 -treated than in CaCl 2 -treated soils.Ca-ion activity in the liquid phase is the main factor responsible for the insolubilization of MPR and the formation of insoluble Ca-P phases (HCl P). The formation of Ca-P solid phases increased with the concentration of Ca-ions, and was governed by the pH and nature of the accompanying anion. For soils with low levels of exchangeable cations and where liming is a recommended intervention measure, Ca from lime will form insoluble P phases and reduce the dissolution of PR and P availability to plants.
