nitrifiable

_ -- If we suppose that a solution containing a nitrifiable substance is supplied with the nitrifying organism, and with the various food constituents necessary for its growth and activity, the rapidity of nitrification will depend on a variety of circumstances:

_ -- The analyses of soils and drainage waters have taught us that the nitrogenous humic matter resulting from the decay of plants is nitrifiable; also that the various nitrogenous manures applied to land, as farmyard manure, bones, fish, blood, rape cake, and ammonium salts, undergo nitrification in the soil.

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

This is due to the fact, that there is generally a certain quantity of nitrogen in most soils in a more easily nitrifiable condition than the rest, so that when this becomes oxidised nitrification proceeds more slowly.

These experiments are interesting as showing what is probably the maximum rate of nitrification under the most favourable circumstances, and where there is an abundant supply of easily nitrifiable nitrogen.

We are well aware that the nitrogen present in the humic matter of the soil is readily nitrifiable.

[115] According to Warington, solutions containing 50 per cent of urine become nitrifiable when sufficient gypsum is added.

Manures and the principles of manuring Charles Morton Aikman

That various manures, such as bones, horn, wool, and rape-cake are readily nitrifiable, has been shown by experiment.

One fact, however, about which there can be little doubt, is that nitrogen in the form of ammonia salts is, of all compounds of nitrogen, the most easily nitrifiable.
