Soil acidity is the most important factor limiting agricultural yield in Brazil and worldwide. Liming stands out among the most effective efficient strategies in solving problems related to soil acidification, however, in no-tillage system conventional procedure of lime incorporation contradicts the viability and conservationist elements of the production system. However, the aim of this study was to evaluate the effect of lime surface aplication on wheat growth and yield in a long-term experiment under no-tillage system. A field experiment was has been conducted since the agricultural year 2002/2003 in a sandy clay loam, kaolinitic, thermic Typic. Treatments included four dolomitic limestone rates (0, 1000, 2000, and 4000 kg ha^–1) which were applied on the surface, without soil incorporation. Surface liming increased the wheat growth and grain yield in Brazilian acidic soils, with higher effects being observed when recommended rate of limestone was applied. In general, plant growth was stimulated by increased availability of essential nutrients and by neutralization of toxic elements such as Al³⁺, which provided better conditions for root development, increasing the efficiency of use of water and nutrients in the crop.
