Nine-Bark

an American shrub of the rose family. It is related closely to the meadowsweet and the steeple-bush.

The purple pods are conspicuous and ornamental. The nine-bark adapts itself readily to lawns.

Niter

or NITRE, an orthorhombic mineral occurring in crusts, silky fibers, acicular crystals, or diffused through certain soils. Composition: Nitric acid, 53.4; potash potash, 46.6 =100, corresponding to the formula, KNO.. In pharmacy it is exhibited in small doses as a refrigerant and diuretic, and in large doses as a vascular sedative in fever, especially in that of acute rheumatism. It has been found useful also in dropsy.

Nitrification

the changing nitrogenous organic matter or ammonia of compounds into nitrates under certain conditions. First, the temperature must be suitable, for at about 5° C. the process is stopped; but with a rise of temperature there is a proportionate increase of work-commencing at about 12° C. till 37° is reached, which is the "optimum" temperature, and from this onward there is a diminution of action until the "maximum" temperature of 55° C. is reached, when nitrification ceases. These bacteroids are annihilated at a temperature of 90° C., although the same result will follow drying even at a much lower temperature. The second condition is the presence of oxygen; and the third is the presence of a salifiable base, such as lime, potash, soda, etc., without which nitrification cannot proceed. Under these conditions nitrification goes on in every fertile soil, the atmospheric nitrogen, nitrogenous organic matter, or ammonia compounds being converted, in the presence of lime or potash, into the corresponding nitrates of lime or potash; and from these nitric compounds plants derive the most or all of their nitrogen.
