and 2-lime sections, but they are abundant in spots on the i-hme and 

 no-Hme sections. Weeds on this plat are not so abundant as on preced- 

 ing plats. The alfalfa on i-lime section is small and pale, except where 

 nodules occur. On the limed sections, however, it is better, but this may 

 be due, to some extent, to drainage. 



Oct. 30. Plat 1 5 16. Scarcely distinguishable in any respect from 

 1515. Nodules are found on the limed and no-limed areas of both. 



Plat 15 17. Check. Plain Seed, Manure and Soil. July 28 



No lime. Lime. 



Alfalfa 95 160 



Grass 23 2>7 



Other weeds 8 26 



Total 126 223 



The plants on this plat, neither weeds nor grass, are so vigorous as 

 on those plats toward the other end of the series, but this end is moist. 

 The alfalfa is generally of good color and well inoculated. On the limed 

 sections the weeds and alfalfa are stronger and more vigorous. (See 



Fig. 93-) 



Oct. 30. Plat 1 5 17. Stand good. Vigor good but greatest at 3- 

 lime and inferior on no-lime section. Slightly less growth of top than 

 on 1 5 14. 



3. Seeding With and Without a Foster Crop 



During 1904 a study was made of the effect of a foster crop on the 

 growth of alfalfa seeding. The seeding was made upon a gravelly loam 

 soil well adapted to alfalfa. A mixture of oats and barley was sown 

 with the alfalfa on part of the area at the rate of one bushel per acre 

 early in Alay. The stand secured was good and the growth normal. The 

 field was clipped twice during the summer. Critical study of both areas 

 was made on July 12, just before the first clipping, and November 3, at 

 the end of the growing season. 



For purposes of study a representative spot was selected in each area 

 and one-half square yard was carefully taken from each and the growths 

 separated into theii classes, counted and weighed. The following table 

 shows the result of this examination :
