Excerpt from Bulletin of the Department of Agriculture, Vol. 2: January, 1904 This axiom of Nature, when referred to the nitrogen contained in living things, finds its justification and realisation in fact by the relationship of nitrates to the decay and the re-creation of the materials of which all forms of life are composed. The last stage in the decay of nitrogenous matter from plants and animals is that of the nitrates formed in the soil, and this again is the first stage in which the dead matter is taken up afresh by the growing plant and re-created into the substance of living matter. In the tropics this cycle is appreciably accelerated by conditions favourably adapted towards swiftness of decay and a regeneration frequently miraculous in the speed of its attainment. A knowledge of the process of nitrification underlies an intelligent comprehension of the principles of soil management, of cultivation and manuring. The most valuable commercial form of nitrogenous fertilizers for use in a tropical country of free rainfall, as in the cultivated areas of Jamaica, is Sulphate of Ammonia. An attempt will be made to give an account of the process whereby ammonia derived from organic decay or the commercial fertilizer is converted into nitrate for the direct nutrition of a crop. Nitrification. Although plants are able to feed upon ammonia dissolved in the soil water, they rarely do so under normal conditions.
