THOMAS SLAG. 238 THOMPSON. age of available phosphoric acid and of silica, but in being practically devoid of free lime. Basic slag is not suited to the manufacture of super- phosphates and is generally used without any treatment except fine grinding. Purchasers of Thomas slag should insist on its being finely ground, as the value of the material depends very largely upon its fineness. Slag has be.en used in large quantities for agricultural purposes in Europe for a number of years— in 1S09 1,05.5,000 tons. Of this 895,000 tons were used in Germany and 170.000 in France. In ISSo the use of this material was practically confined to Germany and amounted to only 5000 tons. Since the total consumption of phosphatic fertilizers in Germany in 1899 was 1,804,000 tons, and in France 245,000 tons, nearly half of the phosphatic fertilizers used in these countries was Thomas slag. Slag has not been extensive!}' introduced into the United States. Some has been manufactured at I'ottstown, Pa., and put on the market under the name of 'odor- less phosphate.' Experiments have shown slag to be a very valuable phosphatic fertilizer, and on account of its higli percentage of lime espe- cially suited to use on acid soils and those rich in organic matter. It would not be wise to use it freely on poor sandy soils deficient in organic matter. Experiments have indicated that slag and dissolved boneblack are about equallj' ef- fective, taking into account the after-effects of the slag, while the cost of the latter is nearly twice that of the former. Slag appears to be especially suited to legumi- nous crops. Six liundrcd to one thousand pounds per acre is considered a liberal dressing. It should not be mixed with ammonium sul]ihate before use, since its high percentage of free lime is likely to cause a loss of ammonia by volatiliza- tion. Mixtures of the slag with other salts, such as muriate of potash and nitrate of soda, cake badly and are difficult to handle and dis- tribute uniformly. See Manures a.d ^Ianub- ING.
