Summary1. Studies were made on the decomposition of a substrate containing glucose, ammonia, and nitrate in soil held under differing aeration conditions.2. When water slurries were incubated with substrate, the loss of total-N equalled the loss of nitrate plus nitrite nitrogen.3. Under percolation conditions, with small amounts of substrate and an oxygen partial pressure of 15.2 cm of mercury, there was little change in nitrate or nitrite concentrations. Loss of nitrate only occurred under… 

Nitrification and nitrate dissimilation in soil

TLDR
It is concluded that at an oxygen concentration of 2 to 5 µM nitrate dissimilation took place at about half of its rate under an atmosphere of nitrogen, and nitrification took place when oxygen was not limiting, and the soil-physical conditions under which biological nitrogen losses can take place are defined.

Influence of oxygen on denitrification and aerobic respiration in soil

SummaryThe influence of the partial pressure of oxygen on denitrification and aerobic respiration was investigated at defined P02 values in a mull rendzina soil. The highest denitrification and

The effect of nitrate and nitrous oxide on hydrogen and methane accumulation in anaerobically-incubated soils

SummaryThe effect of KNO3 and N2O on the accumulation of CH4, H2 and denitrification products in two North Dakota soils during anaerobic incubation at 30°C was studied by means of gas chromatography.

Contribution of nitrification and denitrification to nitrous oxide emissions in Andosol and from Fluvisol after coated urea application

Nitrogen (N) fertilizers applied on agricultural fields are an important source of nitrous oxide (N2O). The use of coated fertilizer is known to mitigate fertilizer derived N2O emissions; however,

Influence of the water regime on denitrification and aerobic respiration in soil

SummaryThe influence of soil moisture on denitrification and aerobic respiration was studied in a mull rendzina soil. N2O formation did not occur below −30 kPa matric water potential (Ψm), above 0.28

A mathematical model of oxygen uptake by bacteria in agricultural soils is presented with the goal of predicting anaerobic regions in which denitrification occurs. In an environment with a plentiful

Acetylene reduction (dinitrogen fixation) and nitrification in soil as affected by the structural aggregate size

TLDR
Aggregates of a larger diameter exhibited a considerably higher nitrogenase activity than those with a diameter smaller than 2 mm, and this effect was even more pronounced when the soil samples were repeatedly intensively aerated.

The potential of controlled traffic farming to mitigate greenhouse gas emissions and enhance carbon sequestration in arable land: a critical review

The drive toward adoption of conservation agriculture to reduce costs and increase production sustainably causes concern due to the potentially negative effects of increased soil compaction. Soil

Denitrification studies on some South Australian soils

TLDR
The levels of soil organic carbon which occur in surface soils in sub-humid regions may be too low to provide sufficient energy material for active metabolism of denitrifying organisms even if all other conditions for the denitrification process are optimal.

TLDR
It would appear that after the first crop of barley the presence of the manurial additions of tare residues, and especially of ammonium sulphate, tends to hinder the formation of leachable nitrogen in the soil.

Studies on true dissimilatory nitrate reduction

TLDR
Cells grown autotrophically—at the expense of hydrogen—are able to oxidize organic compounds without noticeable adaptation and in the simultaneous presence of hydrogen and an organic compound both substrates are oxidized independently.
