“…Fixation of microbial P by soil during the extraction period can reduce the precision of Pm estimates. Sometimes corrections for P fixation are made by spiking a reference sample with Means followed by the same letter are not significantly different (P < 0.05) P at the beginning of the extracting period, and then using the portion of the spike recovered after extraction to estimate the amount of Pm fixed by the soil during extraction (Brookes et al 1982, McLaughlin et al 1986). Soils with high P sorption capacities may have lower Kp values (Hedley and Stewart 1982).…”

“…Soil preparation for Pm determination may vary among different procedures. Sometimes the soil has been dried, sometimes ground, and sometimes used in the original field-moist state (Brookes et al 1982, Hedley and Stewart 1982, Selles et al 1995. Air drying or grinding soils may cause quantitative and qualitative changes in biota and biomass (Brookes et al 1982, McLaughlin et al 1986).…”

“…O Cmic e o Nmic foram obtidos através da diferença entre as amostras fumigadas e não fumigadas. A concentração de fósforo microbiano foi determinada em espectrofotômetro UV-VIS em comprimento de onda de 882 nm (BROOKES et al, 1982). Calculou-se o Pmic através da diferença entre as amostras fumigadas e não fumigadas.…”
