“…AcPME activity in the L (16.9-70.0 μmol p-NP g −1 h −1 , same unit for the below enzyme activity) and F/H (33.8-68.9) horizons were generally comparable to the values reported in a Douglas-fir forest in Canada (mixture of L horizon to H horizon 35.5; Pang and Kolenko, 1986) and a pine plantation in New Zealand (L horizon 21.8, F horizon 74.4; Chen et al, 2000) using similar analytic procedure. PDE activity in the L (0.9-3.7) and F/H (0.7-2.3) horizons covered the values in the pine plantation in New Zealand (L horizon 1.2, F horizon 2.3; Chen et al, 2000).…”

“…In comparison with the data obtained by Clarholm (1993) in the humus layer of a spruce forest, and Adams (1992) and Pang and Kolenko (1986) in forest soils, the APA was high at all sites, in particular at GS1. Phosphatases are inducible enzymes, and hence their excretion by microorganisms and plant roots is regulated by end-product inhibition.…”

The acid phosphatase activity (APA) is a key factor in phosphorus (P), mineralization, P nutrition of plants, and P cycling. However, the widely used method of Tabatabai and Bremner for APA determinations is seriously restricted in soils with high organic matter contents, owing to interference in photometric detection by dissolved organic matter. The objectives of this study were: A) to modify the procedure of Tabatabai and Bremner with a view to its application to forest soils rich in organic carbon, b) to determine APA contents in forest soils of the Sierra de Gata mountains, and c) to establish relationships between the APA with different soil parameters. The modified procedure was well

“…Lack of improvement with inoculation indicated that the last hypothesis was more likely the case. Spiers & McGill (1979) and Pang & Kolenko (1986) found that microbial phosphatase activity was inhibited by an increase in the amount of inorganic P. In heated soils, synthesis of active phosphatases might not be required because of an increase in the labile-P or other forms of P released during heating, particularly in BFG and PC soils, which had P contents higher than in controls after 160 days of incubation. Adams (1992) proposed similar explanations for a lack of phosphomonoesterase and phosphodiesterase activity in burned soils six months after fire.…”

Abstract. The effect of soil heat and autoclaving on labile inorganic P (Bray I), microbial P (P-flush) and on phosphatase activity was studied by heating five forest soils in the laboratory, which simulated the effects of heat during bushfires. Top soil was heated to 60 'C, 120 'C and 250 "C or autoclaved for 30 minutes. Soils were analysed immediately after heating and during seven months of incubation to assess immediate and longer-term effects of heating.Labile inorganic P increased immediately after heating and autoclaving soils, with the highest amount recorded for the 250 'C treatment. Phosphorus associated with microbial biomass decreased with heat, and none or small amounts were detected in soils heated to 250 "C and autoclaved, because high temperatures killed the microbial population. Most of the P released from microbes acted as a source of labile inorganic P in soils low in inorganic P, and some of the released P was fixed by the soil. In one soil high in inorganic labile P and with undetectable amounts of microbial-P, the increase in Bray P on heating could only be assigned to solubilisation of other sources of total P. Because high temperatures denature enzymatic proteins, phosphatase activity diminished with the increase in temperature, and no activity was detected in 250 'C and autoclaved soils.Phosphorus released by heating decreased during incubation in three of the five soils studied, approaching values observed in unheated soils. Simultaneously, an increase in microbial P was observed in these heated soils, indicating that the partial recovery of microbial biomass acted as a sink for the decrease in Bray-P measured. Phosphatase activity recovered only partially during incubation of heated soils.
