Soil Sampling and Methods of Analysis, Second Edition
1994) depending on the quantity of mineralizable organic N in the soil and
environmental conditions (soil temperature and moisture) that control the rate of
mineralization. Large amounts of mineralizable N can accumulate under
grassland ...

Improved Crop Quality by Nutrient Management
Mineralizable C and N The effects of different cropping systems on mineralizable
C and N were significant at 1 % level (Table 3). Mineralizable C was highest in
the soils of fruit orchards and vegetables, possibly due to intensive fertilization.
Dilek Anaç, Pierre Martin-Prével, 1999

Soil Organic Matter in Sustainable Agriculture
Seasonal differences in mineralizable C can occur as a result of pulses of C
inputs from plant roots and aboveground residues. In a Fluventic Ustochrept in
Texas, mineralizable C at wheat planting was 89% higher under no tillage than
under ...
Fred Magdoff, Ray R. Weil, 2004

Soil Quality for Crop Production and Ecosystem Health
Soils under longer rotations receiving adequate amounts of fertilizer usually have
relatively greater amounts of mineralizable N. Biederbeck et al. (1984) reported
that mineralizable N in adequately fertilized continuous wheat was 45% higher ...
E.G. Gregorich, M.R. Carter, 1997

Soil Mineral -- Microbe-Organic Interactions: Theories and ...
3.1.4 Potentially Mineralizable C and N Potentially mineralizable C and N are
often measured by incubating a sample of field-moist soil at a known temperature
in a sealed chamber containing an alkali trap. The CO2–C accumulated in the
trap ...

Soil Management: Experimental Basis for Sustainability and ...
A third approach to measuring changes in the supply of mineralizable soil N, and
one adopted in many of the experiments included in this review, is to use a
chemical extraction procedure (Table 8). This method is attractive, as it is
generally ...

Urban Ecology: An International Perspective on the ...
(1995) examined the carbon dynamics of forests along the study transect in detail
, separating the soil carbon into four pools: 1) readily mineralizable carbon with a
turnover time of days to weeks; 2) labile carbon with a turnover time of weeks to ...
John Marzluff, Eric Shulenberger, Wilfried Endlicher, 2008

Sustainable Potato Production: Global Case Studies: Global ...
The standard laboratory-based method to quantify soil mineralizable N was
developed by Stanford and Smith (1972) to estimate soil potentially mineralizable
N (N0). The N0 is determined using a long-term aerobic incubation, and therefore
...
Zhongqi He, Robert Larkin, Wayne Honeycutt, 2012

Handbook of Soil Analysis: Mineralogical, Organic and ...
Different names are used for the methods such as nitrogen availability indices,
potentially mineralizable nitrogen, net mineralization, mineralization potential.
The biological methods tend to simulate in vitro the evolution of the soil in natural
...
Marc Pansu, Jacques Gautheyrou, 2007

Soil Carbon Sequestration and the Greenhouse Effect
From a compilation of studies, mineralizable C and N were generally greater
under NT than under inversion-tillage systems (Table 16-3). As with other pools
of organic matter, differences in mineralizable C between tillage systems tend to
be ...
