Peat temperature, physicochemistry, organic carbon pools, basal CO(2) respiration and extracellular enzyme activities (beta-glucosidase, phosphatase, sulphatase and phenol oxidase) were monitored monthly. The results of a principle component eigenanalysis of field data show that concentrations of basal CO(2) respiration, soil solution DOC and phenolics were positively correlated to soil temperature (P<0.01, F=12.25; P<0.001, F=59.8; P<0.001, F=141.27) with Q(10) responses of 2.29, 6.42 and 14.42, respectively. Extracellular enzyme activities, however, were more strongly associated with seasonal changes in ion concentrations and did not correspond significantly to temperature alone suggesting limitations attributable to a combination of continuous anaerobiosis and/or the suppressive compounds. Restraints on soil enzyme activities may limit the loss of CO(2) from the microbial community that is dependent on soil enzyme activities for nutrient availability. The seasonal effect of temperature on DOC may be explained by increased plant rhizodeposition and microbial activity. These results do not imply that the long-term increasing trend in DOC export is explainable by temperature increase but suggest that temperature may be a key factor regulating the seasonal variation in DOC concentrations. Thus, seasonal temperature effects on DOC may represent an important component of long-term models of DOC export.", "keywords": ["Wales", "phenolics", "Climate", "beta-Glucosidase", "Temperature", "04 agricultural and veterinary sciences", "DOC", "Carbon Dioxide", "Hydrogen-Ion Concentration", "15.

Currently, it is not clear to what extent different rates of poultry litter impact soil microbial communities, which control nutrient availability, organic matter quality and quantity, and soil degradation potential. From 2002 to 2004, we investigated the microbial community and several enzyme activities in a Vertisol soil (fine, smectitic, thermic, Udic Haplustert) at 0 to 15 cm as affected by different rates of poultry litter application to pasture (0, 6.7, and 13.4 Mg ha\uffe2\uff88\uff921) and cultivated sites (0, 4.5, 6.7, 9.0, 11.2, and 13.4 Mg ha\uffe2\uff88\uff921) in Texas, USA. No differences in soil pH (average: 7.9), total N (pasture: 2.01\uffe2\uff80\uff933.53, cultivated: 1.09\uffe2\uff80\uff931.98 g kg\uffe2\uff88\uff921 soil) or organic C (pasture average: 25\uffe2\uff80\uff9326.7, cultivated average: 13.9\uffe2\uff80\uff9316.1 g kg\uffe2\uff88\uff921 soil) were observed following the first four years of litter application. Microbial biomass carbon (MBC) and nitrogen (MBN) increased at litter rates greater than 6.7 Mg ha\uffe2\uff88\uff921 (pasture: MBC = &gt;863, MBN = &gt;88 mg kg\uffe2\uff88\uff921 soil) compared to sites with no applied litter (MBC = 722, MBN = 69 mg kg\uffe2\uff88\uff921 soil). Enzyme activities of C (\uffce\uffb2\uffe2\uff80\uff90glucosidase, \uffce\uffb1\uffe2\uff80\uff90galactosidase, \uffce\uffb2\uffe2\uff80\uff90glucosaminidase) or N cycling (\uffce\uffb2\uffe2\uff80\uff90glucosaminidase) were increased at litter rates greater than 6.7 Mg ha\uffe2\uff88\uff921 Enzyme activities of P (alkaline phosphatase) and S (arylsulfatase) mineralization showed the same response in pasture, but they were only increased at the highest (9.0, 11.2, and 13.4 Mg ha\uffe2\uff88\uff921) litter application rates in cultivated sites. According to fatty acid methyl ester (FAME) analysis, the pasture soils experienced shifts to higher bacterial populations at litter rates of 6.7 Mg ha\uffe2\uff88\uff921, and shifts to higher fungal populations at the highest litter application rates in cultivated sites. While rates greater than 6.7 Mg ha\uffe2\uff88\uff921 provided rapid enhancement of the soil microbial populations and enzymatic activities, they result in P application in excess of crop needs. Thus, studies will continue to investigate whether litter application at rates below 6.7 Mg ha\uffe2\uff88\uff921, previously recommended to maintain water quality, will result in similar improved soil microbial and biochemical functioning with continued annual litter application.</p>", "keywords": ["2.
