Comparison of humic fractions of Chernozemic and Luvisolic soils by elemental analyses, UV and ESR spectroscopy, A
Author(s):Paul, E. A.; Anderson, D. W.; Russell, D. B.; St. Arnaud, R. J.
Date Issued:1974-11
Format:born digital; articles
The Ah horizons of a Brown–Dark Brown–Black–Dark Gray–Gray Luvisolic sequence of Canadian grassland and forest soils were studied. Clay-associated humus was present in greater proportions in the grassland than in forest ...
Extraction and charaterization of humus with reference to clay-associated humus
Author(s):Anderson, D. W.; Paul, E. A.; St. Arnaud, R. J.
Date Issued:1974-08
Format:born digital; articles
An extraction-fractionation method was developed with which it is possible to isolate 60–67% of the humus of Chernozemic and Luvisolic soils. Two humic acid fractions were obtained: (1) a conventional alkali-pyrophosphate ...
Decomposition of wheat straw and stabilization of microbial products
Author(s):Voroney, R. P.; Anderson, D. W.; Paul, E. A.
Date Issued:1989-02
Format:born digital; articles
This research examined the effects of soil environment on the decomposition of cereal crop residues and stabilization of microbial products in the field. Microplots at semi-arid and subhumid field sites were amended with ...
