Liming alters chemical soil attributes and favors root development, but its efficiency depends on the incorporation form and the physical and chemical characteristics of the soil. This experiment was carried out to evaluate the efficiency of incorporated or surface liming seven years after its application on a Hapludalf under no-tillage system and located in Santa Maria, RS, Brazil. The replicated treatments consisted of four surface lime rates (0.0; 2.0, 8.5 and 17.0 t ha-1), incorporated by one plowing followed by two diskings. […]
