LEAL, Aguinaldo José Freitas et al. Limestone application methods and cover crops in the implementation of the no-till system on a cerrado soil. Rev. Bras. Ciênc. Solo [online]. 2008, vol.32, n.spe, pp.2771-2777. ISSN 1806-9657.  https://doi.org/10.1590/S0100-06832008000700022.

The objective of this study was to evaluate soil correction in the implantation of the no-till system in an Oxisol of the Cerrado, Selvíria - MS, Brazil (20º 22´ S, 51º 22´ W). The treatments consisted of five lime application forms, in only one or split rates and two cover crops. Liming without incorporation, independent of the application form, corrected soil acidity and increased Ca and Mg levels in the 0-0.05 m layer; in the other layers these attributes were not significantly changed. Limestone incorporation in the layer 0-0.2 m, uniformly modified the values of soil pH, Ca, Mg and sum of bases to a depth of 0.2 m. Sorghum as cover crop led to higher Ca, Mg concentrations, when liming was split in three applications.
