This mixture is particularly effective to increase the growth of 

 established timothy meadows. Many farmers have tried out the 

 treatment on different soils and have found it profitable. As an 

 example may be mentioned a field purchased by Cornell University 

 and made up of the same grade of clay loam as that on which the 

 experiment is conducted.* The field of six acres has been cut 

 three years and was giving a yield estimated at one and one^fourth 

 tons. The foregoing fertilizer treatment gave yields as follows: 



1910 3.34 tons 



1911 2.62 tons 



1912 3.00 tons 



1913 • 2.86 tons 



MANURE AS A FERTILIZER FOR TIMOTHY 



In Table I, the largest increase in yield is produced by stable 

 manure and is to some degree proportionate to the application. 

 The net return is not, so large as that from a complete fertilizer 

 with a double application of nitrogen because of the large cost of 

 the material. This was rated at $1.50 a ton on the land, which is 

 not an unreasonable figure. The manure added every two years 

 would carry a quarter more nitrogen and potassium than the fer- 

 tilizers for the three-year period. The result bears out the state- 

 ment above, that with a moderate supply of minerals the yield is 

 roughly proportionate to the nitrogen applied. The same result 

 was secured at the Ohio station, where timothy appears in a five- 

 year rotation preceded by clover. At the Massachusetts station, a 

 4 per cent larger yield of timothy with some clover was secured 

 from a spring application of manure, which had stood in a pile 

 during the winter, than from fall and winter applications. The 

 result is not conclusive, since only one year's yield is reported. 

 In practice, under average conditions, such a result is hardly to 

 be expected. 



Many farmers have realized from experience the profits to be 

 derived from the use of manure on their new grass seeding rather 

 than on old sod for grain. In the experiment at Cornell Univer- 

 sity mentioned previously, an application of the manure to the
