“…In greenhouse studies on acid soils treated with lime to produce varying pH levels, plant accumulation of Cd applied in fertilizer amendments was higher from a loamy as compared to sandy soil (He and Singh 1994a,b), with the difference being attributed to the higher yields and higher native soil Cd on the loamy soil. In studies in Manitoba and Saskatchewan, plant Cd accumulation was higher on light-texture than heavy-textured soils, due to the lower sorptive capacity of the low CEC, lighttextured soils (Grant et al 1996;Selles 1996).…”

“…Sparrow et al (1994) reported that application of KCl promoted higher Cd content of potato tubers than application of an equivalent amount of K as K 2 SO 4 , but McLaughlin et al (1995) showed no difference between the two sources in similar studies with potatoes. Application of KCl increased the Cd concentration of barley grain (Grant et al 1996). The increased uptake of Cd with KCl application may be a result of increased Cd complex formation in the presence of Cl -, which would result in decreased Cd sorption and greater Cd availability for crop uptake.…”

“…NITROGEN. Nitrogen fertilizers can increase Cd concentration in plants, although the fertilizer does not normally contain significant levels of Cd (Table 5) (Andersson 1976;Oliver et al 1993;Grant et al 1996). The increased plant uptake of Cd with N application may be due to increases in osmotic strength of the soil solution, ion exchange reactions, or soil acidification.…”

“…Fertilizers in general may increase Cd uptake by plants through improvement in plant growth, rooting intensity and mass flow. The effect of fertilizers on Cd accumulations in crops tends to be greater in sand than in clay soils (Eriksson 1990;Grant et al 1996). Sands have a lower Cd sorption ability and a lower average soil water content than the clay, which may result in a higher Cd concentration in the soil solution and a higher Cd uptake by the plant.…”

Cadmium is a heavy metal present in soils from natural and anthropogenic sources. Plant uptake of Cd at levels present in the soil solution is dependent on a system that is largely metabolically mediated and competitive with the uptake system for Zn and possibly other metals. Much of the Cd taken up by plants is retained in the root, but a portion is translocated to the aerial portions of the plant and into the seed. The amount of Cd accumulated and translocated in plants varies with species and with cultivars within species. Soil, environmental and management factors impact on the amount of Cd accumulated in plants. Potential methods of reducing the accumulation of Cd in crops include reduction of Cd input to the soil system, site selection, management practices which decrease the concentration of Cd in the soil solution and its uptake and translocation by plants, and development and production of plant cultivars with the genetic tendency for low Cd uptake.

“…Application of ammonium nitrate increased Cd concentration in malting barley when soil nitrate levels were low, with increased Cd concentrations in the grain generally being associated with increasing crop yields (Grant et al 1996). As N fertilizer does not normally contain appreciable amounts of Cd, the increase in Cd accumulation in crops with N application is presumably from acidification or increased ionic strength of the soil solution, which could increase Cd solubility and phytoavailability (Lorenz et al 1994;Naidu et al 1994).…”

. 1998. Nitrogen, phosphorus and zinc management effects on grain yield and cadmium concentration in two cultivars of durum wheat. Can. J. Plant Sci. 78: 63-70. Cadmium concentration in durum (Triticum turgidum) grain may be influenced by fertilizer management. A 3-yr field study conducted on two Orthic Black Chernozemic soils investigated the effects of banded and broadcast applications of N and P, and applications of Zn fertilizer on the yield and Cd concentration of the grain of two cultivars of durum wheat. Applications of N and P fertilizer increased grain yield of durum wheat when soil nutrient supply was low or yield potential was high, while Zn application generally had little effect on grain yield. Cadmium concentration of durum increased with applications of N and P and was generally unaffected by Zn application. Method of application of N or P did not consistently influence either grain yield or Cd concentration of the grain under the conditions of this study. Where differences due to placement occurred, banded P produced higher grain yield and Cd concentration than application of the same level of P as a broadcast treatment. Cadmium accumulation increased substantially with N and P applications, since both Cd concentration in the grain and grain yield increased with N and P application. Year-to-year variation in Cd concentration in the grain was large, indicating a strong effect of environment on Cd phytoavailability.Key words: Management, banding, nutrient, accumulation Grant, C. A. et Bailey, L. D. 1998. Effets de la conduite de l'alimentation en N, en P et en Zn sur le rendement grainier et sur la teneur en Cd du grain chez deux cultivars de blé dur. Can. J. Plant Sci. 78: 63-70. La concentration de cadmium dans le grain du blé dur (Triticum turgidum) peut être influencée par la conduite de la fumure. Dans une étude au champ de 3 ans réal-isée sur deux sols chernozémiques noirs orthiques, nous avons observé les effets d'apports en bandes en ou nappe de N et de P, ainsi que d'apports de Zn (ZnSO 4 ) sur le rendement grainier et sur la concentration de Cd dans le grain de deux cultivars de blé dur. La fumure N et P augmentait le rendement en grain lorsque le sol était pauvre en ces éléments ou que sa productivité potentielle était déjà forte. En revanche, l'apport de Zn n'avait généralement que peu d'effet à cet égard. Les concentrations de Cd dans le grain augmentaient avec la fumure N et P, mais elles étaient en général insensibles aux apports de Zn. Dans les conditions expérimentales utilisées, le mode d'épandage de N ou de P n'avait d'effet régulier ni sur le rendement grainier ni sur la teneur du grain en cadmium. Toutefois là où des différences étaient observées, le P localisé en bandes donnait un rendement grainier et une concentration de Cd plus forts que la même dose épandue en nappe. L'accumulation de Cd dans le grain augmentait sensiblement avec les apports de N et de P du fait, à la fois de l'augmentation de la concentration de Cd dans le grain et du rendement grainier. La concentration ...
