Effect of the Application the Limestone and Steelmaking Slag in the Content and Accumulation of Silicon in Bermuda Grass Leaf.

The practice of the liming can improve the development of grass, providing a higher density and color most suitable. The most used concealer is Limestone, although other materials can promote the same effect, as the Steelmaking Slag. The aim of this study was to compare the application of limestone and steel slag, by checking the silicon on Bermuda grass. The experiment was conducted Lageado Farm, Faculty of Agricultural Sciences, in Botucatu / SP. It was used blocks divided randomly, into 5 x 2 factorial with four replications, two correctives (Limestone and Steelmaking Slag) and five doses to raise the base saturation (12, 30, 50, 70 and 90%). The silicon concentration, present in the bermuda grass was determined by the method of Korndorfer et al (2004), and the data were statistically analyzed by Tukey. The results showed that there was an increased accumulation of silicon in the Bermuda grass leaf after increasing doses corrective, and it was higher when used the Steelmaking Slag. And the most high content of silicon was found at dose 90 of the Steelmaking Slag. Therefore, it is concluded that the Steelmaking Slag provided greater content and accumulation of silicon in the leaves of Bermuda grass when compared to limestone.
