The objective of the present study was to assess the effect of the modes of lime incorporation on the correction of soil acidity and on corn production. An experiment was conducted on Typic Hapludox of clay texture in Uberlândia - MG, Brazil, from May 1995 to March 1997. The experimental design consisted of a split-plot scheme. The main plots consisted of the modes of lime incorporation: heavy harrow (14 disks of 0.86 m) and leveling harrow (60 disks of 0.56 m); disk plow (4 disks of 0.66 m) and a leveling harrow; super heavy harrow (14 disks of 0.86 m) and a leveling harrow. The subplots were doses of dolomitic lime of 0; 6 and 9.2 t ha-1. The mode of lime incorporation affected the efficiency of liming in terms of soil profile. The heavy harrow was inadequate for lime incorporation. Plowing with a super heavy harrow plus level harrowing showed a satisfactory performance, reaching a depth of as much as 0.20 m. Harrowing with a super heavy harrow provided a greater uniformity and depth of incorporation, with neutralization of soil acidity to a depth of 0.30 m. Corn responded in a linear manner to lime incorporation, with the mode of incorporation by harrowing with a super heavy harrow providing a greater production.
