VALUE OF BARN YARD MANURE. 



The farmer who has lands which should be built up' 

 should feel that he has fed cattle at a profit when manure 

 is obtained free above all other expenses as this manure 

 has an exceedingly high fertilizing value. 



"Beef cattle should be more generally introduced be- 

 cause of the good they do in building up and maintain- 

 ing soils. Under the present system of cotton farming 

 the soils are becoming poorer and poorer. \Mth the in- 

 troduction of cattle the soil will begin to be built up. 

 Director Thorne, of the Ohio Station, has been making 

 tests with barnyard manure for several years, applying 

 the manure upon a plot of ground upon which was run- 

 ning a three years' rotation of corn, wheat, and clover. 

 Eight tons of manure an acre were applied. The aver- 

 age yearly increase an acre, following the one applica- 

 tion, was as follows: 



Corn, 14.7 bushels at 70 cents a bushel $10.29" 



Corn stover, 744 pounds at $6.00 a ton 2.23 



Wheat, 8.36 bushels at $1.00 a bushel 8.36- 



Wheat straw, 897 pounds at $4.00 a ton 1.79 



Glover hay, 686 pounds at $12.00 a ton 4.12'^ 



Total value of 8 tons of manure 26.79 



Total value of 1 ton of manure 3.35- 



He further states (Bulletin 183 Ohio Experiment Sta- 

 tion) that the value of farm manure can be materially 

 increased by balancing the manure with the addition of 

 a carrier of phosphorus. The farm manures are too 

 high in nitrogen as compared with the other elements.. 

 By balancing stable manure, the value of 8 tons was in- 

 creased $12.20 after deducting the cost of the material: 

 used for the balancing of the manure. This is $1.53 a 

 ton and when added to the $3.35 above, brings the total- 

 possible value of each ton of manure up to $4.88. Dur- 

 ing a feeding period of 100 days each steer will produce' 

 at least 1.5 tons of manure. This profit should be added' 

 to the feeding or direct profits.
