to grass and clover with the oats in 1891, Two crops of hay were 

 cut in each of the years 1892 and 1893. 



1. Nitrogen in the form of nitrate of soda increased the yield of 

 g7Xiss in a marked degree, while neither phosphoric acid nor potash 

 exercised any great effect. 



2. The potash applied controlled the development and growth of 

 clovers. 



3. The first cut in each year (mostly grasses) was most affected 

 by the application of nitrate of soda ; the second cut (rowen, mostly 

 clovers) was increased chiefly by the potash. 



i. Results which have been obtained in other parts of the state 

 and by other investigators are in entire agreement with our own. 



Our conclusions for grass and clover stated with reference to the 

 three questions proposed are : — 



1. Grass is similar in its requirements to oats (nitrogen in the 

 form of nitrate of soda most beneficial) : the clovers are to a con- 

 siderable extent similar to corn in their dependence upon potash, 

 but are more benefitted by phosphoric acid than the latter. 



2. The "special" fertilizers for grass lands are not properly 

 compounded whether for grasses or for the clovers. They contain 

 too little nitrogen for the former ; too little potash for the latter. 

 The average of those offered in 1893 was : Nitrogen, 4.02 ; phos- 

 phoric acid, 8.30, and potash, 5.52 per cent. I w^ould recommend 

 for use, where timothy is to be grown, a fertilizer supplying the ele- 

 ments in the following proportions : Nitrogen, 8 ; phosphoric acid, 

 3 ; potash, 3. For manuring where clover is desired : Nitrogen, 2 ; 

 phosphoric acid, 5, and potash, 10. 



3. Maximum crops of hay at minimum cost, whether of grasses 

 or clovers, are not to be looked for from the application of phos- 

 phates. 



With Rye: — This crop was sown after corn in the fall of 1894. 



1. Potash in the form of muriate increased the crop somewhat 

 more largely than either nitrogen (nitrate of soda) or phosphoric 

 acid (dissolved bone-black) ; but the rye showed a greater degree of 

 dependence upon all the fertilizers applied than any preceding crop. 

 This was no doubt in consequence of the greater degree of soil ex- 

 haustion resulting from one-sided manuring which had then been 

 continued for six years.
