Pastures in New York. 505 



Very little of interest can he said regarding the effect of the various 

 fertilizers used in the experiment. No accurate method has been devised 

 of measuring their effect on a pasture. At this date, 19 10, there appears 

 to be no perceptible difference in the amount of grass growing on the 

 plots receiving various fertilizers. Even the Hmed plots do not appear 

 better than the unhmed. One or two of the plots which received stable 

 manure seem to be superior to the neighboring plots which received 

 commercial fertilizers. The difference is not marked. 



CONCLUSIONS FROM THE PRESWICK PASTURE EXPERIMENT 



Kentucky blue-grass is the only plant, which, when sown alone, has 

 produced a permanent pasture. All others which were sown alone 

 have become reduced in number to such an extent as to become un- 

 profitable for grazing. 



Kentucky blue-grass has not spread to a profitable degree into those 

 areas of the field which did not receive it in the seeding. It is often 

 remarked that it is unnecessary to sow blue-grass in New York because 

 it is a "natural grass." Timothy has shown up in this respect better 

 than Kentucky blue-grass. 



Meadow fescue and brome-grass are failures when sown alone on 

 this type of soil. Meadow fescue has been a fairly good grass in mixtures. 



For this type of soil Kentucky blue-grass and white clover should always 

 be used in mixtures intended for permanent pastures. Do not wait for 

 them, to appear without seeding. To the above add timothy, red-top 

 and red and alsike clover for use the first two or three years. The latter 

 grasses will begin to disappear when the blue-grass gets established. 



For temporary pastures, timothy, red-top, and common red clover 



were most successful. These grasses could be cut for hay the first year. 



Canadian blue-grass appears on this type of soil without seeding. 



It has not crowded out Kentucky blue-grass as yet. It is relished 



by cattle but does not supply, a large amount of herbage per given area. 



THE ROBERTS PASTURE 

 I. P. Roberts 



I have been requested by Director L. H. Bailey to give in detail 

 the history of the field on the University Farm now known as the 

 Roberts pasture. 



When I arrived at Cornell University in the spring of 1874, I found 

 there, as part of the farm, a somewhat irregular piece of land of about
