Dynamics of yard trimmings composting as determined by dehydrogenase activity, ATP content, arginine ammonification, and nitrification potential
(Elsevier, 2002-04-06)
Microbial activities, numbers, and biomass are key parameters that can be used to elucidate the dynamics of the composting process. In the present study, four different biochemical parameters (dehydrogenase activity, ATP ...
Effects of mulching and fertilization on soil nutrients, microbial activity and rhizosphere bacterial community structure determined by analysis of TRFLPs of PCR-amplified 16S rRNA genes
(Elsevier, 2002-07-30)
Organic mulches such as recycled, ground wood pallets and composted yard waste are widely used in landscapes to suppress weeds, and improve plant health. However, little is known about how mulches affect soil or rhizosphere ...
Characterization and composting of poultry litter in forced-aeration piles
(Elsevier, 2002-03-07)
The environmental problems associated with raw poultry manure application could be mitigated by stabilizing its nutrient and organic matter (OM) contents by composting before application to agricultural soils. In the present ...
Microbial population dynamics and enzyme activities during composting
(Taylor & Francis, 2002-01-01)
The changes in population size of different microbial groups (total aerobic heterotrophs, actinomycetes, fungi, fecal coliforms, ammonium- and nitrite-oxidizing bacteria, and denitrifying bacteria) and the activities of ...
Carbon, nutrient, and mass loss during composting
(Springer Nature, 2002-05-15)
Hoop manure (a mixture of partially decomposed pig manure and cornstalks from swine fed in hoop structures) was the subject of a nitrogen mass balance during the feeding period. The manure was then composted in windrows ...
Evolution of extracellular enzyme activities during manure composting
(Oxford University Press (OUP), 2002-01-01)
Aims: The objectives of this work were to determine the extracellular enzyme profiles during composting, relate the activities of these enzymes to the changes in microbial population and compare the enzyme profiles between ...
