“…The results presented here are similar to those reported by Rocha et al (2011), who found that the residual effect of silicate tended to enhance the K concentration in sorghum leaves. This result can be a consequence of improved root growth, once Si application enhances root structures, as reported by Carvalho-Pupatto et al (2003). In addition this increase in Ca concentration in the wheat leaves ( Figure 3b) is due to supply of this nutrient with calcium silicate rates.…”

An improvement in soil properties and crop development with silicate application has been confirmed in several plant species. This study investigated the effect of application of calcium silicate on nutrition and yield of wheat (Triticum aestivum L.). Wheat plants were grown in 8-L pots filled with clayey Rhodic Hapludox in a greenhouse. The experiment was arranged in a completely randomized design, with five treatments, and four replicates. The treatments consisted of growing wheat plants with 0 (control), 1.2, 2.4, 4.8 and 9.6 Mg ha -1 of calcium silicate (Ca 2 SiO 4 ). Calcium silicate increased the pH of the soil, and the silicon concentration in leaves and stems of the wheat. Nitrogen (N), phosphorus (P), magnesium (Mg), sulphur (S), copper (Cu), and iron (Fe) concentrations in the wheat flag leaves were not affected by the application of calcium silicate, whereas the K and Ca concentrations were increased and the Zn and Mn concentrations were reduced by the application of calcium silicate rates. The application of calcium silicate rates did not affect plant height, number of spikes per pot, shoot dry matter, grain yield and harvest index of wheat.

“…However, they focused on the evaluation of the acidity correction and Ca, Mg, and Si supply under field conditions (BARBOSA FILHO et al, 2001;KORNDÖRFER et al,2001;CARVALHO-PUPPATTO et al,2003) and pots (PEREIRA et al,2004;KORNDORFER et al, 1999;CAMARGO et al, 2007b) and only a few studies (RAMOS et al, 2008) have evaluated the benefits of Si supply for the rice crops on its uptake, yield and quality without the additional effects (increasing on pH and Ca and Mg content in soils) of silicate applied in tropical soils. The Ca and Mg levels in soil had to be used in the same quantities when different silicate rates were applied in soil, as already done in incubation studies of Si sources and rates (CAMARGO et al, 2007a;PEREIRA et al, , 2010.…”

“…Diversos estudos (Pereira et al, 2004;Carvalho-PuPatto, 2003;Berni e PraBhu, 2003) têm demonstrado que as gramíneas respondem favoravelmente à adubação silicatada, particularmente quando cultivada em solos com baixos teores de Si "disponível".…”

RESUMOA cana-de-açúcar é uma espécie acumuladora de silício (Si), capaz de responder à adubação silicatada, principalmente, em solos pobres desse elemento. As escórias de siderurgia constituem em uma interessante fonte de Si para aplicação em solos cultivados com essa cultura. Objetivou-se estudar o aproveitamento do Si proveniente da escória siderúrgica pela cana-de-açúcar. O experimento foi desenvolvido em Uberlândia (MG), entre 15 de agosto de 2007 e 2 de maio de 2008. O delineamento experimental utilizado foi o de blocos ao acaso em esquema fatorial 2x4, sendo duas cultivares de cana-de-açúcar (SP81 -3250 e RB86 -7515) e quatro doses de Si (0, 100, 200 e 400 kg ha -1 ) em quatro repetições. A cana foi cultivada em tambores plásticos (200 L). A aplicação de escória de siderurgia (silicato) aumentou o teor de Si disponível no solo e o teor foliar da cana-de-açúcar. A quantidade de Si acumulada pela parte aérea da cana proveniente do silicato aplicado variou entre 23% e 56%, respectivamente, para as variedades RB86-7515 e SP81-3250. Em média, 39% do Si absorvido pela parte aérea da cana foram provenientes do fertilizante aplicado (silicato).Palavras-chave: silicato, Si solúvel, recuperação de silício, Si acumulado. ABSTRACT RECOVERY OF SILICON FROM METALLURGY SLAG BY SUGARCANE CULTIVARSSugarcane is a species that accumulates silicon (Si) and is capable of responding to Si applications, especially in soils lacking Si.. Metallurgy slag is an interesting source of Si for soils cultivated with this crop. The aim of this study was to evaluate the recovery of Si from metallurgy slag by sugarcane. The experiment was carried out at Uberlândia-MG, from August 15, 2007 to May 02, 2008. The experimental design was randomized in a 2 x 4 factorial arrangement being two cultivate of sugarcane (SP81 -3250 and RB86 -7515) and four Silicon doses (0, 100, 200 and 400 kg ha -1 ) with four replications. The sugarcane was cultivated in plastic drums (200 L). The application of slag (silicates) increased the content of available silicon in soil and leaf of sugarcane. The amount of Si accumulated in the aerial part of sugarcane from the silicate applied ranged between 23 and 56% respectively for the variety RB86-7515 and SP81-3250. On average, 39% of Si absorbed by the shoot of the sugarcane came from the fertilizer applied (silicate).Key word: silicate, soluble Si, silicon recovery, accumulated Si.( 1 ) Recebido para publicação em 9 de outubro de 2008 e aceito em 21 de janeiro de 2010.
