106 CHEMICAL MANURES. 



tilizers of M. George Ville on a property I possess at Charras, 

 canton of Moulbron. 



The lands on which the experiments were made were three acres in 

 extent. They were manured, one-half with 1066 pounds of the com- 

 plete fertilizer No. 2, containing 



Acid phosphate of lime 355 Ibs. 



Nitrate of potash 179 " 



Nitrate of soda 266 " 



Sulphate of lime .. 266 " 



Total 1066 Ibs. 



The other half with 888 pounds of the incomplete fertilizer No. 2, 

 containing 



Acid phosphate of lime 355 Ibs. 



Sulphate of ammonia 310 " 



Sulphate of lime 223 " 



Total 888 Ibs. 



The results obtained from these two kinds of fertilizers showed no 

 difference to the eye before harvest. It was always my intention to 

 separate them, but they were unfortunately mixed by a mistake of 

 my steward. 



'The harvest was 99 bushels of wheat and 11,127 pounds of straw, 

 which gave 33 bushels of grain and 3709 pounds of straw the acre ; 

 while that year the returns from five other farms and reserves form- 

 ing the same property only rose to 15 bushels of grain and 1829 

 pounds of straw the acre. 



To give a clear idea of the money value of this first trial permit 

 me, gentlemen, to enter into some details. 



The total extent of this farm which was sown in wheat was 6 

 acres ; the stable manure to be spread over this surface did not con- 

 stitute, according to the bad habit of our country, a half manuring. 

 I had it spread over 3 acres that is, over half the surface for which 

 it was designed. The chemical fertilizers Nos. 1 and 2, to the weight 

 of 3909 pounds, were spread over the remaining 3 acres. 



The total harvest was raised 'to 117 bushels of wheat and 13,452 

 pounds of straw. 



Judging by the five other farms and reserves of this year, the har- 

 vests of this farm, without manure, would have been ordinarily 72 

 bushels of wheat at the most. 



The use of the chemical fertilizers increased the harvest by an 

 excess of 117 over 72 equal to 45 bushels of grain and 5191 pounds 

 of straw. 



The 45 bu. of wheat, at $1 .75 the bu., gave $78.75 



The 5191 Ibs. of straw, at .004! per Ib 24.65 



Total . 8103.40 



The fertilizers and all expenses included J5.42 



The net profit is, the first year $27.08
