Abstract

The objective of this research was to quantify the microbial biomass carbon (MBC) and evolved CO₂carbon (CO₂–C), mycorrhizal colonization, soil fertility and corn production under different soil managements and surfacelimestone application. For that, an experiment was carried out consisting of four treatments, as follows: two soil managements notillage (NT) and minimum tillage (MT) and two limestone treatments (0 and 2 t ha¹), with four replications. Soil managements affected the soil chemical attributes in the 00.10 m depth layer: the highest P values were observed in MT and the lowest Al levels in the NTtreatments. Once no significant differences were found among treatments for the evaluated microbial variables and corn yield, it allowed affirming that it is possible to avoid disruption of the notill sequence by applying lime on the soil surface, once the incorporation of organic matter and limestone caused little changes to the system stability.
