Evaluation of Several Indices of Potentially Mineralizable Soil Nitrogen

Communications in Soil Science and Plant Analysis, 2007
Abstract A routine soil test that accurately predicts soil nitrogen (N) mineralization has long eluded researchers. Soil incubations, which are not practical for routine soil testing, are the only methods that have proven successful. Although several quick analytical methods have been proposed, no one method has correlated consistently enough to be ...

A Rapid Method to Estimate Potentially Mineralizable Nitrogen in Soil

Soil Science Society of America Journal, 2002
Rapid estimates of mineralizable N in soil are important for management decisions and soil quality assessments. We adapted and evaluated a rapid method based on measuring the gas pressure generated when soil is treated with Ca(ClO) 2 in a closed vessel.

Evaluation of Some Indices of Potentially Mineralizable Nitrogen in Soil

Soil Science Society of America Journal, 2007
A series of soil N mineralization indices were evaluated using 153 samples chosen from arable fields representing a wide range of soil types, management practices, and climatic zones. These indices were compared against potentially mineralizable N (N 0 ) determined by aerobic incubation at 25°

Achieving Desired Moisture Conditions in Potentially Mineralizable Nitrogen Incubation Studies

Soil Science Society of America Journal, 1986
Abstract A technique was developed to determine soil‐to‐sand mixing ratios to achieve desired soil moisture conditions during incubation in potentially mineralizable N studies. Five soils were selected to represent a range of soil textures. Segmented plastic leaching tubes were used to determine gravimetric water content, bulk density,

Potential of Chemically Labile Fractions to Measure Mineralizable Soil Nitrogen

Communications in Soil Science and Plant Analysis, 2009
Nitrogen (N) in the soil is largely organic and is available to crops only after it is mineralized to inorganic N by microbial or enzyme action. To develop a soil test for guiding N applications, a method to predict the relative amount of organic N that will mineralize in a growing season is necessary.

Seasonal Variation of Potentially Mineralizable Nitrogen in Four Cropping Systems

Soil Science Society of America Journal, 1987
Abstract The concept of potentially mineralizable N is discussed and data that support the identification of N 0 as an active fraction of soil organic N are presented.

Estimation of potentially mineralizable soil nitrogen from chemical and taxonomic criteria

Communications in Soil Science and Plant Analysis, 1982
Abstract Estimates of mineralization of soil organic N are often needed to predict N fertilizer requirements of crops. G. Stanford and his collaborators developed laboratory techniques to estimate potentially mineralizable N (NO) in soils and a rate constant for mineralization (k).
