Soil acidity is a major limitation to crop productivity, in tropical soils. The MATOPIBA region present irregular distribution of rainfall, and the lime reaction effectively begins with the beginning of the rainy season, coinciding with the recommended soybean sowing period. Therefore, there is not enough time for the lime to react completely before plant establishment. We aimed to evaluate the effects of liming rates in areas newly converted from native Cerrado to the soybean-millet crop sequence in Maranhão, Brazil.
