An experiment to determine the amount of manure made by 

 a cattle beast during the successive periods of its growth, C. A. 



Zayitz {Ontario A(/l. Col. and ihptl. Farm Rpt. 18'Jo, pp. 121-123).^- 

 The amounts of food consumed, litter used, and manure produced by 

 a calf (luring- the first 3 years of its life are reported. 



The results, calculated to G-month periods, are given in the following 

 table :

A sample of manure taken from the stall near the close of the experi- 

 ment contained moisture 53.r>l per cent, nitrogen 0.()3 per cent, phos- 

 phoric acid 0.83 per cent, potash 1.94 per cent. Reckoning the value 

 of the manure from this analysis on the basis of valuation used for 

 commercial fertilizers, the manure produced during the 3 years was 

 worth $118.57. 



Commercial fertilizers, H. A. Huston and W. J. Jones, Jr. {Fur- 

 ilue Univ. Spec. Bid. ISOi, Ai({/., pp. 11). — ISTotes on the extent of the 

 fertilizer trade in Indiana in 1890. on the character of the fertilizers 

 oflered for sale in the State, on the draft of different crops upon soil 

 fertility, on the use of fertilizers, and on valuation, accompanied by 

 tabulated analyses and valuations of 312 samples of fertilizers legally 

 on sale in the State. 



"The estimated sales of commercial fertilizers in ludiana duriug the year 1893 

 amount to 38,000 tons, au increase over the sales in 1892 of 3,000 tons. This 38,000 

 tons of fertilizer consisted of 14,000 tons of bone, raw and steamed; 18,000 tons of 

 'complete' fertilizer, that is, fertilizer contaiuino- nitrogen, phosphoric acid, and 

 potash; 4,000 tons of ammoiaiated phosphates; 1,000 tons of phosphate and potash; 

 and 1,000 tons of plain superphosphate. The aggregate selling price would amount 

 to over $1,000,000. 



"A change is taking place in the character of the fertilizers sold in the State. 

 This change consists of a relative increase in the amount of phosphoric acid con- 

 tained in the fertilizers and a relative decrease of nitrogen and a relative decrease 

 of potash. The total quantity of phosphoric acid contained in the fertilizers sold 

 in the State in 1893 was 12,900,000 lbs., the total quantity of ammonia was 2,300,000 

 lbs., and the total quantity of potash 770,000 lbs. If we compare these quantities with 

 the quantities sold in 1889 we find that there has been a relative increase in the 

 amount of phosphoric acid of 10 per cent, a relative decrease in the amount of 

 anunonia of 3 per cent, and a relative decrease of potash of 9 per cent. . . . 



"Information is not at hand to determine the cause of the change in the relative 

 quantities of nitrogen, phosphoric acid, and potash used in the State."'
