 from time to time as suiBcient reliable data are secured. In this 

 connection we would say that there has been some impatience shown 

 by local farmers and others, which at times is shared in a measure 

 by the writer, but we have endeavored to lay the foundations for 

 good, solid future work, publishing only such data as we deemed re- 

 liable rather than attempt to secure maximum yields regardless of

Our work with fertilizers has shown, as a rule, that the soils od 

 this farm do not respond profitably to applications of nitrogen or 

 potash, but respond readily to applications of phosphoric acid. As 

 an extreme example, an application of 200 pounds per acre of 14 

 per cent acid phosphate gave an increase of 11 bushels of oats per 

 acre, while an application of nitrogen and potash slightly decreased 

 the yield. Practically the same results have been secured with other 

 crops. Two extra cultivations gave ten bushels increase of corn per 

 acre. A difference of from 39 to 52 bushels of corn per acre was 

 shown due to variety planted. Equally striking results in oats, 

 wheat and potatoes have been shown due to the same factor, t. e.
