Abstract

Silicon (Si) is an element beneficial to plant development by providing increased capacity to defend against the attack of pests and diseases, and to ensure an more erect plant, which increases their photosynthetic capacity. Silicon sources such as silicates of calcium and magnesium, providing Si to the soil and can act as acidity correctors. No-till system - NT in conjunction with the application of silicate can interfere with the Si availability to plants and the forms of this the element in the soil solution. However, studies related to Si in soils under NT are scarce, especially in long-term experiments conducted under humid tropical conditions. Since 2002 is being conducted field experiments in Oxisol under NT, with support from FAPESP, that assesses surface application of soil acidity correctors (lime and calcium silicate and magnesium). In this work will be determined the levels of available soil Si and the species of Si in the soil solution and the correlations of these species with levels of available soil Si and soil attributes.
