Catalase activity increased with the highest rate of compost, but urease and phosphatase activities were significantly inhibited P # 0 : 05 in the organic amended soils..
Assays of o -DPO activity were performed in sterilised soil samples to evaluate the abiotic chemical oxidation of catechol in soil under aerobic conditions, in the presence and
The rate of P release by total PMEase activity was esti- mated using the concentration of SNP (50% of which was assumed to be PME), and the estimated kinetic parameters for the
The aim of this research was to establish changes in the overall activity of extracellular enzymes: b -glucosidase, phosphomonoesterase, arylsulphatase, protease and urease and
Leaf litter decomposition (expressed as percent mass remain- ing) of single and mixed pine and oak litter in litter bags placed on the soil surface or buried in the organic horizon
Reductions in the diversity of plants and litter inputs, and changes in litter quality associated with management intensi®cation, may also in¯uence the soil microbial biomass
Maturity and quality were determined for indi- vidual fruit at harvest and after storage by analy- ses of fruit respiration rate, internal ethylene concentration (IEC), flesh
Although peak respiration rate increased as temperature increased from 30 to 45°C, ethylene production induced by propylene was inhibited at temperatures over 38°C.. This
