Examples

  • You could not expect it to nitrify humus while it was also being required to digest organic matter.

    Organic Gardener's Composting

  • It can't digest crude organic matter and simultaneously nitrify humus.

    Organic Gardener's Composting

  • A thin layer of solution will nitrify sooner than a deep layer, owing to the larger proportion of oxygen available.

    Scientific American Supplement, No. 470, January 3, 1885

  • R. Warington, J.T. Schloessing, C.A. M├╝ntz and others had proved that nitrification was promoted by some organism, when Winogradsky hit on the happy idea of isolating the organism by using gelatinous silica, and so avoiding the difficulties which Warington had shown to exist with the organism in presence of organic nitrogen, owing to its refusal to nitrify on gelatine or other nitrogenous media.

    Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy"

  • Warington at Rothamsted, who showed that the power of nitrification could be communicated to media, which did not nitrify, by simply seeding them with a nitrifying substance, and that light was unfavourable to the process.

    Manures and the principles of manuring

  • At any rate it seems to be invariably the case that when a mixture of nitrogen compounds, including ammonia salts, are allowed to nitrify, the nitrogen in the form of ammonia is the first to become nitrified.

    Manures and the principles of manuring

  • This is the reason why strong urine solutions do not nitrify.

    Manures and the principles of manuring

  • It said measures needed to be put in place to de-nitrify the final effluent; phosphorus removal may also be required.

    An Irish Town Planner's Blog

  • After separation of the solids, approximately 6 - 8 hours of aerobic treatment will breakdown the BOD and nitrify the ammonia quite nicely.
