report of these experiments was made in Bulletin ITO. A notice- 

 able fact developed by these experiments is that the coiiclusions 

 reached on one farm are rarely aj^plicable on another, but are of 

 real practical value where the experiment was conducted. 



These experimental sets of fertilizers are not to be had on the 

 general market, though farmers bujnng the cliemicals in the usual 

 packages may weigh out the required amounts for their own use. 

 Usually they will prefer to receive them ready for use through 

 arrangement with the College of Agriculture. 



During the past seasons the College has supplied, free of cost, the 

 fertilizers used in the experiments. The funds available for this 

 purpose are so limited that not nearly all the farmers who desire to 

 make the tests could be supplied, and of course only a small fraction ^ 

 of those who ought to do so. It has been decided for the next 

 season, instead of supplying sets of experimental fertilizers free to 

 a few^ farmers, to make arrangements whereby all farmers wdio 

 desire, or can be induced to take up the work, can secure the fer- 

 tilizers at small cost — that is at the market price of the goods plus 

 the extra cost of putting up in sets. Each set consists of two large 

 sacks in which are seven small sacks containins: and labeled as 

 follows : 



Plat 1 — K 15 pounds muriate of potash. 



Plat 2 — N 20 pounds dried blood. 



Plat 3 — P 30 pounds acid phosphate. 



Plat 5 — KK . . .35 pounds mixture of 20 pounds dried blood. 15 



pounds nniriate of potash. 

 Plat 6 — PK. . . .45 pounds mixture of 30 pounds acid phosphate, 



15 pounds muriate of potash. 

 Plat 7 — JSTP. . . .50 pounds mixture of 20 pounds dried blood, 30 



pounds acid phosphate. 

 Plat 8 — NPK . . 65 pounds mixture of 20 pounds dried blood, 30 



pounds acid phosphate, 15 pounds muriate of 



potash. 



The contents of each small sack are to be applied to a correspond- 

 ing plat of land. These plats may be one-tenth or one-twentieth of
