The effects of a 7-day incubation (at 25C and 50% of water-holding capacity, -0.001 MPa) of two soils, from under grazed pastures of high and low P status, on microbial C, N, P and ATP contents, numbers and respiration were investigated with samples collected in summer and winter. Incubation prior to analysis (i.e. storage or pre-incubation) resulted in a significant (P < 0.05) alteration in most of the properties measured; seasonal effects were often marked with the two soils generally behaving similarly. Microbial numbers and respiration increased during prior incubation of summer samples, but generally decreased in winter samples. Pre-incubation resulted in a decrease in biomass C, as estimated by the chloroform fumigation procedure, but an increase in ATP content. Changes in mineral-N flush and biomass P were smaller and less consistent. Many of the properties measured were still changing after 7 days incubation. |
