Nitrification in acidic soils may occur at pH-neutral microsites that are as small as the immediate surroundings of ammonifying microorganisms (De Boer et al.
These pH-neutral microsites have been suggested to be as small as the immediate surroundings of the ammonifying microorganisms (Prosser 1989; De Boer and Kowalchuk 2001).
The model experiment helped to study the influence of temperature, moisture, and density on nitrifying and ammonifying capacity of sod-podzol midclay low-humic soil.
Ammonifying bacteria was determined in the culture medium of protein agar medium, and organic phosphorus- solubilizing bacteria was determined in that of Meng Jina's agar.
Bacteria, fungi, actinomycetes, and ammonifying and nitrifying bacteria were counted by plating 0.1 mL of suitable dilutions on separate plates and incubated at temperature 28[degrees] C.
(2005) found average counts of Bacillus sp., ammonifying bacteria and protein mineralizing bacteria were significantly higher in ponds with application of commercial probiotics compared to the control ponds.
In studying the effect of cultivation on the microflora of dark chestnut soils in Akmola region, it was found that cultivation significantly increases the number of ammonifying bacteria.

It has been shown that in black alder the size of the total microbial population and the numbers of ammonifying and proteolytic microorganisms were higher in the plant rhizosphere and soil-root interface than in bulk soil, litter, and root-free soil under trees [24].
1998), inoculation of non-symbiotic nitrogen-fixing bacteria boosted the activities of ammonifying and nitrifying flora towards mineralisation of organic nitrogen in rice soil (Ghosh et al.
Well mixed 0.05 mL samples of dilutions from 10-3 to 10-7 (in sterile deionized water) were spread in triplicate onto the following media for culturable microbe enumerations, bacteria were determined in the culture medium of Beef-cream and Peptone, actinomycete were determined in the culture medium of improved Gao 1, fungi on Martin's agar, azobacter was determined on Ashby- Sucrose agar medium, ammonifying bacteria on protein agar medium, aerobic cellulose-decomposing bacteria on agar according to Waksman, organic phosphorus- solubilizing bacteria on Meng Jina's agar, inorganic phosphorus-solubilizing bacteria on the culture medium of calcigenol simple and glucose, potassium-solubilizing bacteria on potassium aluminium silicate agar (Xu and Zheng, 1986).
This result indicates that the ammonifying organisms in the subsoil are severely inhibited by the acidic conditions at depth, and are not able to undertake net mineralisation even when there is an abundance of a readily mineralisable substrate present.
