What's the difference between nigrification and nitrification?
Nigrification
Definition:
(n.) The act or process of making black.
Example Sentences:
Nitrification
Definition:
(n.) The act, process, or result of combining with nitrogen or some of its compounds.
(n.) The act or process of oxidizing nitrogen or its compounds so as to form nitrous or nitric acid.
(n.) A process of oxidation, in which nitrogenous vegetable and animal matter in the presence of air, moisture, and some basic substances, as lime or alkali carbonate, is converted into nitrates.
Example Sentences:
(1) A comparison of the effects observed for three pesticides, dieldrin, chlorpyrifos and Vorlex, in three soil types with those produced by an antibiotic, a fungicide, a nitrification inhibitor and steam pasteurization of the soil clearly demonstrate the effectiveness of the simple technique.
(2) An experiment on the effects of pesticides on nitrification in the percolator is described.
(3) The sufficient concentration of the active ingredients to inhibit the nitrification are lower than the fungicidal concentrations.
(4) However, nitrification is a cause of significant errors in measuring BOD, particularly when a large population of nitrifying organisms are existing in water such as effluents from biological treatment plants.
(5) Simultaneous processes of nitrification and denitrification were observed in optimal aerated manure similar to activated sludge processes.
(6) The effect of size of structural aggregates on the intensity of nitrification and nitrogenase (nitrogen: acetylene oxidoreductase) activity was investigated in three soils.
(7) Changes in microbial population determined by the dilution plate method, in nitrification by the soil perfusion technique, and in oxygen consumption using a differential respirometer are the only measurements required.
(8) The biotest presented permits the investigation of sewage as for the presence of nitrification-inhibiting substances.
(9) On the contrary, smaller aggregates (0.5-2 mm) exhibited more intensive nitrification.
(10) When nitrate was used, the nitrification was not delayed.
(11) The effects of two herbicides, Sencor and Goltix, on nitrification in two soils were studied using a mixed culture of nitrifying bacteria.
(12) Heterotrophic nitrification by another organism, a strain of "Pseudomonas denitrificans" has also been shown to be inhibited by thiosulphate in short term experiments and in the chemostat.
(13) The combination of increased concentrations of oxidized nitrogen with decreased total chlorine residuals can be used as a rapid indicator of bacterial nitrification.
(14) Bacterial toxicity tests are based on bioluminescence, motility, growth, viability, ATP, oxygen uptake, nitrification, or heat production.
(15) The biotest was successfully applied in order to find out the inhibition of nitrification in a communal purification plant.
(16) Inhibitors thought to be specific to ammonia oxidizers have been used in environmental studies of nitrification.
(17) Ammonification, nitrification, urea transformation, and decomposition of cellulose are enhanced by the increased occurrence of bacteria and actinomycetes.
(18) Sencor (10 ppm, 50 ppm, and 100 ppm) has no inhibitory influence on nitrification.
(19) The overall nitrification activity was, however, essentially unaffected by the oxygen concentration.
(20) Nitrification usually returned to a relative equilibrium in several days after the herbicide application.
