In the period from October 2008 to October 2009, soil samples were collected in the 0?10 cm layer and were subjected to the treatments: control, without application of urea or manure; and with the application of urea, pig slurry, and deep pig litter in two doses, in order to supply one or two times the recommended N doses for the maize (Zea mays)/black oat (Avena strigosa) crop succession. The carbon of the microbial biomass (MB-C) and the basal respiration (C-CO2) were analyzed, and the metabolic (qCO2) and microbial quotient (qmic) were calculated with the obtained data. Organic matter, pH in water, available P and K, and exchangeable Ca and Mg were also determined. The application of twice the dose of deep pig litter increases the MB-C and C-CO2 values. The qmic and qCO2 are little affected by the application of swine manure. The application of twice the dose of deep pig litter increases the values of pH in water and the contents of available P and of exchangeable Ca and Mg in the soil.  aEnvironmental quality  aNo-tillage  aPig manure  aSoil quality  aBioquimica do solo  aEsterco  aQuímica do solo  aSuíno1 aCOMIN, J.
