“…The NH 4 -form of cation exchange resin may also be desirable in K supply rate assessment as the potassium ion present in the clay mineral interlayers can be more easily exchanged by the ammonium ion than the sodium ion. For example, our data showed 1.5 times more K extracted by NH 4 + saturated resin than by Na saturated resin (Qian et al 1996a). For anion exchange resin, we use HCO 3 -as a counterion because the HCO 3 -displaced by nutrient ions in soil mimics to a certain extent the HCO 3 -produced in the rhizosphere due to the excretion of CO 2 by plant roots and microorganisms.…”

“…1). In this study, although available K extracted by all four methods had strong relationships with canola and wheat K uptake (r 2 = 0.63 to 0.73), only the CEM burial method performed equally well in soils representing all pH ranges, implying that it functions well as an indicator of relative K availability in a diverse array of soil types (Qian et al 1996a). Good relationships of 1 h membrane burial with commonly used chemical extraction methods have also be found for N, P and S in a 3 yr study using more than 400 soil samples from across Saskatchewan (Qian and Schoenau 1996).…”

“…For K, in a study using 19 soil samples (Qian et al 1996a), potassium extracted by 1 h CEM burial was significantly related to the K extracted by 1 M NH 4 OAc, ASI (Jin and Portch 1991), and boiling 1 M HNO 3 (Fig. 1).…”

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...

“…Although very convenient, the sole use of nutrient concentrations as indicators of soil fertility also has its disadvantages. Depending on the chemical extraction solution used to process soil samples, nutrient concentration measurements for a particular nutrient will vary greatly [58], which makes standardization very difficult among results obtained from different extraction methods. In addition, accurate evaluation of soil NO 3 is complicated by the fact that the NO 3 concentration in a soil sample can change significantly if the sample is not handled properly once collected [37].…”

This study had three main objectives: (1) to evaluate the aboveground biomass and volume yield of three unrelated hybrid poplar clones in 9 year-old riparian buffer strips located on four farms of southern Québec, Canada; (2) to compare yield data at 9 years with previous data (at 6 years); (3) to evaluate how soil fertility, measured using three different soil testing methods (soil nutrient stocks, soil nutrient concentrations, soil nutrient supply rates), is related to yield. Across the four sites, hybrid poplar productivity after 9 years ranged from 116 to 450 m ) were observed at all sites, but the productivity gap between the less fertile site and the three other sites was widened. Clone MxB-915311 was the most productive across the four sites, while clone DxN-3570 was the least productive. However, at the most productive site, clone MxB-915311 experienced severe stem and branch breakages. Independently of the soil testing method used, available soil P was always the first soil factor explaining volume yield. OPEN ACCESSSustainability 2013, 5 1894

“…This measurement of K availability provides an indication of the supply of readily available K to an adsorbing surface, taking into account replenishment of soil solution K by the solid phase as well as movement by diffusion and competition with other cations (Qian et al 1996). Cation PRS TM probes (Western Ag Innovations, Saskatoon, SK) were charged by soaking in 0.5 M HCl for 2Á4 h to saturate the exchange sites with H ' ions.…”

. 2013. Does the presence of the gene for glabrous hull in annual canarygrass affect the response to chloride fertilizer? Can. J. Plant Sci. 93: 109Á118. Annual canarygrass is an important cereal crop in western Canada with a unique niche market as feed for caged birds. Chloride (Cl) fertilizer has been shown to increase seed yield in annual canarygrass; however, the response was only tested in one glabrous cultivar. Currently, glabrous cultivars created through mutagenesis, are lower yielding than cultivars with trichomes on their lemma, palea and glumes. The objective of this study was to determine if the mutagenic process which created cultivars that lack trichomes on their lemma, palea and glumes also affected the response of annual canarygrass to chloride fertilizer. A two-way factorial study was conducted across 7 site-years. The first factor was Cl applied at two rates (0 and 18.2 kg Cl ha(1 ) and the second factor was four cultivars (Keet, Cantate, CDC Togo (glabrous) and CDC Bastia (glabrous). The application of Cl increased the seed yield of annual canarygrass by 25% and most of this increase was due to a 21% increase in seeds per panicle. Kernel weight also contributed to increased seed yield. Chloride did not interact with the presence or absence of trichomes and therefore growers can expect to receive a yield increase from the application of Cl regardless of the annual canarygrass cultivar grown. Growers should apply 9 kg ha(1 of Cl when growing annual canarygrass. In conclusion, Cl is not involved in the physiology of the lower yield in glabrous cultivars compared with cultivars with trichomes, and Cl could not explain the seed yield differences between the two types of annual canarygrass.Key words: Canaryseed, annual canarygrass, environmental conditions, seed yield, yield stability May, W.

Plant Sci. 93: 109Á118. L'alpiste roseau est une importante ce´re´ale annuelle dans l'ouest du Canada. Cette culture occupe un cre´neau unique, qui est celui de la nourriture pour les oiseaux en cage. On sait que les engrais a`base de chlore (Cl) accroissent le rendement grainier de l'alpiste, cependant, cette re´action n'a e´te´teste´e que sur un cultivar glabre. Or, a`l'heure actuelle, les varie´te´s glabres, qui re´sultent de la mutage´ne`se, s'ave`rent moins productifs que les cultivars pre´sentant des trichomes sur leur lemme, leur pale´ole et leurs glumelles. L'e´tude devait e´tablir si le processus de mutage´ne`se a`l'origine des cultivars sans trichomes sur le lemme, le pale´ole et les glumelles modifie aussi la re´action de l'alpiste roseau annuel aux engrais renfermant du chlore. À cette fin, les auteurs ont proce´de´a`une expe´rience bifactorielle pendant 7 anne´es-sites.
