Effect of soil acidification on nitrification in soil
Canadian Journal of Soil Science, 2015Zebarth, B. J., Forge, T. A., Goyer, C. and Brin, L. D. 2015. Effect of soil acidification on nitrification in soil. Can. J. Soil Sci. 95: 359–363. This laboratory experiment examined the effect of elemental S-induced variation in soil pH (3.97–5.29) on nitrification enzyme activity and conversion of [Formula: see text] to [Formula: see text ...

Effect of soil acidification on the soil microflora
Water, Air, and Soil Pollution, 1979The effects of short and long term acidification on a few Alberta soils were studied with respect to bacterial numbers and total soil respiration. Significant reductions in bacterial numbers were observed in both short and long term acidified soils. Total soil activity was severely affected in an acid soil (pH 3.0, longterm) adjacent to a S block.

Soil Acidification and Alkalinization
1991In this chapter I briefly discuss the nature of soil acidification and alkalinization, and define these processes in terms of changes in the relevant capacity factors. Next, the contribution of various sources of soil acidification and their quantitative importance is treated in some detail: (1) effects of addition of acids or bases by irrigation and ...

A critique of models for freshwater and soil acidification
Water, Air, and Soil Pollution, 1986Four types of models quantifying effects of acid deposition on freshwaters are reviewed. These include Henriksen’s empirical model, an adsorption isotherm model, soil-oriented charge balance models (Reuss-Johnson, Birkenes, MAGIC, ILWAS), and the Trickle Down model.

Dynamics of soil acidification: an economic analysis
Ecological Economics, 1999Abstract This paper studies the dynamic aspects related to the problem of acidification. It shows how accumulation of acidification in ecosystems can be studied in economic modelling by incorporating dynamic aspects of soil acidification. In contrast to the often applied critical loads approach which only focuses on the final state of a soil, the ...

1980
Acidification is a natural process that occurs continuously in soils through which water percolates. Precipitation acidified by industrial pollutants does not constitute a special case but is a source of acidity additional to a number of natural ones. Its effects must therefore be assessed in the context of soil acidification in general.

Acidification of a solonetzic soil by nitrogenous fertilizers
Journal of Environmental Science and Health, Part B, 1982Annual applications of (NH4)2SO4, NH4NO3 and urea on a Solonetzic soil at 112 kg N/ha for 10 consecutive years reduced pH levels from 5.6 for the check to 4.4, 4.9 and 5.3, respectively for (NH4)2SO4, NH4NO3 and urea. (NH4)2SO4 generated twice as much exchange acidity as NH4NO3 and four times as much as urea. Net extractable cations leached from the Ap

Soil and limnologic acidification: a paradox
International Journal of Environmental Studies, 1987Estimated levels of buffering based upon cation exchange capacity and concentration of chemicals present in surface soil of watersheds that contain acidified surface water pose a paradox to reports of low quantities of atmospheric hydrogen ions currently falling upon land in eastern North America, one of the most heavily acidified land areas in the ...

Aluminum weathering in soil acidification modelling
Chemical Geology, 1990Abstract Enhanced dissolution of Aluminum in acidic forest soils is one of the most pronounced soil chemical effects of acidic deposition. Dissolved monomeric Aluminum is toxic to aquatic organisms and has been hypothesized as a major cause of forest die-back in Central Europe (1).

The Sensitivity of Soils to Acidification
1980The sensitivity of a site can be considered as the change produced in some property of the site as a result of an applied stimulus. The applied stimulus here is acid precipitation, but there are many chemical and biological properties of the site which may change as a result of increasing acidification.
