During the past season the field has been cut twice and the 

 product made into hay. The following table gives the yield 

 per plot, the rates of yield per acre, and the gain or loss as 

 compared with the no-phosphate plots, both for the hay and 

 rowen : — 



It will be noticed that both the first and second crops of 

 hay were heavy, the first especially so. This crop had lodged 

 considerably before it could be cut, and there is little doubt 

 that the possible increase due to the fertilizers was some- 

 what diminished through the check in growth consequent 

 upon the badly lodged condition. We do not find the appli- 

 cation of the phosphates to have apparently influenced the 

 yield either of hay or rowen to a very large extent. The 

 results are in harmony with previous observations upon our 

 soils, which have indicated them to require relatively small 

 applications of phosphates for all crops except those belong- 

 ing to the Cruciferse, such as cabbages and turnips. In 1903, 

 when this entire field was planted to cabbages, the yields 

 wherever phosphates were annually applied greatly exceeded 

 the average yield on the no-phosphate plots. The range 

 on the several phosphate plots was from about two to five times 

 the average product of the no-phosphate plots. This year,
