“…Soluble Si in red, gray upland, gray lowland and dark red soils of Okinawa, Japan, under sugarcane cultivation, ranged from 0.9 to 46 mg Si 100 g -1 and was positively related to soil pH Oya and Kina, 1989). In general, Si concentration in solution of highly weathered soils such as Ultisols and Oxisols is several times less than those soils in temperate regions (McKeague and Cline, 1963c;Juo and Sanchez, 1986;Foy, 1992). This may be a possible factor of lower productivity of sugarcane on tropical soils .…”

Silicon (Si) is one of the most abundant elements found in the earth's crust, but is mostly inert and only slightly soluble. Agriculture activity tends to remove large q uantities of Si from soil. Sugarcane is known to absorb more Si than any other mineral nutrient, accumulating approximately 380 kg ha -1 of Si, in a 12-month old crop. Sugarcane (plant growth and development) responses to silicon fertilization have been documented in some areas of the world, and applications on commercial fields are routine in certain areas. The reason for this plant response or yield increase is not fully understood, but several mechanisms have been proposed. Some studies indicate that sugarcane yield responses to silicon may be associated with induced resistance to biotic and abiotic stresses, such as disease and pest resistance, Al, Mn and Fe toxicity alleviation, increased P availability, reduced lodging, improved leaf and stalk erectness, freeze resistance, and improvement in plant water economy. This review covers the relationship of silicon to sugarcane crop production, including recommendations on how to best manage silicon in soils and plants, silicon interactions with others elements, and laboratory methodology for determining silicon in the soil, plant and fertilizer. In addition, a future research agenda for silicon in sugarcane is proposed.

“…Le calcium a généralement pour effet de diminuer la toxicité aluminique (Kinraide et Parker 1987;Noble et Sumner 1988;Blamey et al 1992;Brunet 1994), qui est probablement l'un des principaux facteurs limitants de la croissance des plantes en sol fortement acide (Foy, 1992). En concentration élevée dans la solution du sol, l'aluminium peut en effet avoir un impact très négatif sur la croissance de nombreuses espèces végétales (Adam et Hatchcock 1984;Hue et al 1986;Kinraide et Parker 1987).…”

La racine du ginseng à cinq folioles, une plante originaire des forêts de feuillus de l'est de l'Amérique du Nord, est très recherchée sur le marché asiatique en raison de ses diverses propriétés médicinales. Les populations naturelles de l'espèce étant aujourd'hui menacées, l'approvisionnement des consommateurs repose essentiellement sur la culture. La presque totalité du ginseng à cinq folioles est produite en champ, à très forte densité, sous des structures d'ombrage. Au cours des dernières années, toutefois, de plus en plus de producteurs ont commencé à produire cette espèce en milieu forestier, où les arbres jouent notamment le rôle de procurer l'ombrage nécessaire aux plants. Ce mode de culture, moins coûteux, permet d'obtenir des racines de qualité supérieure et de valeur commerciale beaucoup plus élevée. Des travaux d'aménagement forestier permettent d'assurer une intensité lumineuse adéquate. La litière de feuilles limite les risques de gel des racines. Un sol meuble, bien drainé, possédant un pH légèrement acide ou près de la neutralité et une bonne teneur en calcium permet d'améliorer le rendement et le taux de survie des plants. La protection des populations naturelles est cependant primordiale pour préserver une richesse génétique essentielle au succès futur de la production.Mots clés: Culture en forêt, érablière, gestion de la fertilité, ginseng à cinq folioles, populations naturelles, pratiques culturales Nadeau, I. and Olivier, A. 2003. The biology and forest cultivation of American ginseng (Panax quinquefolius L.) in Canada: A review. Can. J. Plant Sci. 83: 877-891. The root of the American ginseng, a plant that is native in the deciduous forests of the Eastern part of North America, is in demand on the Asian market because of its numerous medicinal properties. Since the natural populations of this species are now endangered, the satisfaction of the demand of the consumers depends on cultivation. Almost all American ginseng is produced in the field, at very high densities, under shade cloths. In the past few years, however, more and more growers have started to produce this species in forests, where trees provide the necessary shade for the plants. This kind of approach, which is less expensive, allows growers to obtain roots of higher quality and of higher retail value. Appropriate forest management allows adequate light intensity. Leaf litter limits the risk of root damage due to frost. A light, well-drained, lightly acidic or neutral and calcium-rich soil allows for better yields and survival rates of the plants. The protection of natural populations is of prime importance to preserve the genetic diversity which is essential to the success of the production in the future.Key words: Forest farming, maple forest, fertility management, American ginseng, natural populations, cultural practices Depuis plus de 40...

“…Aluminum toxicity often restricts root length and diminishes acquisition of essential mineral nutrients. [31] Since this batch of unamended soil had high Al (88% saturation) and low P (3.1 mg kg 21 soil), mineral nutrient toxicities and/or deficiencies would be expected. Phosphorus and Mg deficiencies were common on many plants grown in this and other low pH soils (R.B.…”

Large amounts of flue gas desulfurization products (FGDs) are produced when SO 2 emissions are trapped in the coal burning process for generation of electricity. FGDs are normally discarded instead of being reused, and reuse on soils could be important in overall management of these products. Glasshouse experiments were conducted to determine effects of various levels of three FGDs (a FGD gypsum, an oxidized FGD þ Mg, and a stabilized FGD) and the control compounds CaCO 3 , CaSO 3 , and CaSO 4 on growth of alfalfa (Medicago sativa), white clover (Trifolium repens), orchardgrass (Dactylis glomerata), tall fescue (Festuca arundinacea), switchgrass (Panicum virgatum), and eastern gamagrass (Tripsacum dactyloides) in acidic (pH 4) soil (Typic
