Towards a minimum data set to assess soil organic matter quality in agricultural soils
TL;DR: In this paper, a review of soil organic matter is considered to encompass a set of attributes rather than being a single entity and discussed here are total soil organic carbon and nitrogen, light fraction and macroorganic (particulate) matter, mineralizable carbon, microbial biomass, soil carbohydrates and enzymes.
Journal ArticleDOI
Development of Reflectance Spectral Libraries for Characterization of Soil Properties
TL;DR: In this article, a scheme for development and use of soil spectral libraries for rapid nondestructive estimation of soil properties based on analysis of diffuse reflectance spectroscopy was developed. But the spectral library approach is not suitable for use in agricultural, environmental, and engineering applications.

Labile Organic Matter Fractions as Central Components of the Quality of Agricultural Soils: An Overview
TL;DR: In this paper, the authors considered the sensitivity of individual organic matter fractions to changes in soil management and have specific effects on soil properties and processes, and concluded that individual organics are sensitive to changes and have a specific effect on soil function.
Journal ArticleDOI
Biochar-mediated changes in soil quality and plant growth in a three year field trial
TL;DR: In this paper, the authors investigated the multi-year impact of biochar on crop performance and soil quality with specific emphasis on carbon (C) and nitrogen (N) cycling over a 3 y period.

Nitrogen Mineralization Potentials of Soils
George Stanford,S. J. Smith +1 more
TL;DR: In this paper, a 30-week period at 35C, using incubation intervals of 2, 2, 4, 6, 8, and 8 weeks, was used to determine the net mineralization of 39 widely differing soils.
Journal ArticleDOI
Ammonium Production in Soil under Waterlogged Conditions as an Index of Nitrogen Availability
TL;DR: In this paper, the authors investigated the possibility that methods involving estimation of the ammonium produced by incubation of soil under waterlogged conditions may provide an index of nitrogen availability, which led to development of the following method of assessing mineralizable soil nitrogen:

Mineralization of Organic Nitrogen in Soil
G. W. Harmsen,D.A. van Schreven +1 more
TL;DR: This chapter reviews important papers of research in the field of mineralization of organic nitrogen in soil, beginning with the years preceding World War II.
