Carnauba bagana improves the soil quality cultivated with corn in the semiarid piauiense

The Corn an important role in agriculture, and can be used both human animal food, production of ethanol, medicines glue. However, is verified cultivation practices soil inappropriate management have led to deterioration. Thus, the importance vegetation cover incorporation organic matter these cultivated soils. objective this work was evaluate effect Carnauba bagana maintained on as mulch incorporated macrofauna carbon, municipality Itainópolis, semi-arid region Piauí. areas studied will be: corn area with carnauba bagana, into soil; uncovered preserved native vegetation. epigean edaphic collected, sorted identified at order level. Soil samples collected determine carbon. improved community carbon content. reduced uniformity diversity epigeal macrofauna, Wealth Abundance variables Larvae, Abundance, Richness, Shannon Pielou indices, COS layers 0.00-0.05 0.05- 0.10 m were selected for future studies impact maize region.
