Abstract

Liming is essential for obtaining high yield levels in tropical acid soils. The objective of this study was to evaluate maize nutrition and dry matter yield in soil under liming estimated by three calculation methods and sulfur fertilization. The experiment was carried out under greenhouse conditions, in PVC cylinders, by using one plant per cylinder. Filler dolomite lime was added to an Oxisol collected from native forest, at the 4.2 Mg ha-1, 6.7 Mg ha-1, and 8.0 Mg ha-1 doses, respectively calculated by the exchangeable aluminum, magnesium, and calcium method; base saturation method; and SMP buffer method, combined with three sulfur doses (10 mg dm-3, 30 mg dm-3, and 60 mg dm-3). Control treatments without lime or sulfur were also included. Maize plants were harvested at 45 days after sowing and divided into shoots and roots. The most efficient lime recommendation method for maize was the base saturation method. The application of sulfur doses did not affect the maize development up to the evaluated stage.
