SOILS FERTILIZERS. 1143 



The material was applied to mass lands in connection with superphosphate, 500 

 kg. per hectare I 4 15 lbs. per acre l, and potash salts, 300 kg. per hectare I 267 Ihs. per 

 acre) at rates of 5,000 to 15,000 liters per hectare (about 3,300 to 9,900 gal. per acre) 

 on March 20 and June 8, before and after the first cutting of grass. The Bmaller 

 application produced very little increase in yield. The larger application produced 

 sufficient increase in yield t<> pay the cost of transportation and distribution. The 

 addition of sulphate of iron, 500 ku r . per hectare I 145 lbs. per acre) further increased 

 i lie yield and completely destroyed mosses in the grass. The use of the gas liquor 

 resulted in the disappearance of leguminous plants from the herbage, but favored 

 the development of the graminse. The first application of the liquor burned the 

 grass more or less, but it promptly recovered from this injury. 



The general conclusion reached was that farmers in the vicinity of x-d< works may 

 use this material with advantage if they .-an scenic it free of cost. It may be applied 

 with advantage during the winter on <_ r 'a>s lands or on uncultivated land either 

 directly or in mixture with liquid manure. Since it contain.- only nitrogen, it should 

 he supplemented with phosphatic, potassic, and calcareous fertilizers. It applies 

 directly during the summer it may seriously injure plants, hut it may he safely used 

 in mixtures with soil or compost.

 165,). — A brief note is here given on the composition and fertilizing value of raw and 

 degelatinized hone meal and precipitated hone phosphate. The use and value of the 

 precipitated phosphate as a feeding stuff is also referred to. 



Phosphate rock production, E. ( ). Hovey {Amer. Fert., : ', <l!><»;,, No. ■■'. p. 

 21). — Statements fr< m advance reports of the I'. s. Geological Survey are cited show- 

 ing that the marketed production in 1905 probably exceeded 600,000 long tons as 

 against 530,571 tons in 1904. There was a marked increase in production in Florida 

 and Tennessee and a smaller increase in South Carolina. The average price of phos- 

 phate was higher in 1906 than in 1905 due to increased demand in Fairope.
