A method, Barometric Process Separation (BaPS), was developed for the quantification of gross nitrification rates and denitrification rates in oxic soil using intact soil cores incubated in an isothermal gas tight system. Gross nitrification rates and denitrification rates are derived from measurements of changes (i) in air pressure within the closed system, which are primarily the result of the activities of nitrification, denitrification, and respiration, and (2) of O{sub 2} and CO{sub 2… 
Soil Respiratory Quotient Determined via Barometric Process Separation Combined with Nitrogen-15 Labeling
The barometric process separation (BaPS) and 15 N dilution techniques were used to determine gross nitrification rates on the same soil cores from an old grassland soil. The BaPS-technique separates
Nitrification and denitrification in subalpine coniferous forests of different restoration stages in western Sichuan, China
Nitrification is the biological conversion of organic or inorganic nitrogen compounds from a reduced to a more oxidized state. Denitrification is generally referred to as the microbial reduction of
Nitrification rates and associated nitrous oxide emissions from agricultural soils – a synopsis
Laboratory incubations were performed to estimate nitrification rates and the associated nitrous oxide (N2O) emissions under aerobic conditions on a range of soils from National Agricultural Nitrous
Soil core method for direct simultaneous determination of N2 and N2O emissions from forest soils
In order to quantify N2-emissions from a spruce and a beech site at the Höglwald Forest, a new measuring system was developed, that allowed simultaneous, direct determination of N2- and N2O-emission
Shortcomings in the Commercialized Barometric Process Separation Measuring System
In a growing number of studies, the barometric process separation (BaPS) method has been applied for measuring gross nitrification rates in soil. In 2000, the company Umweltanalytische Mess-Systeme
Seasonal variation of gross nitrification rates at three differently treated long-term fertilisations sites
The formation of nitrate (nitrification) in soils is an important process that influences the form of N available for plant uptake and the potential off-site N losses. Gross nitrification is one of
