NEW FERTILIZER MATERIALS 

 AND BY-PRODICTS 



By H. D. HASKINS 



AND 



COCOANIT MEAL 



By J. B. LINDSEY 



The first part of this bulletin gives a brief statement of the 

 composition and use of some of the more recent fertilizing mate- 

 rials, as well as the fertilizing value of some local by-products. 

 Information is furnished regarding each product mentioned as 

 to its chemical composition and the manner in which it can be 

 best used. Whenever the product is suitable for home-mixing 

 purposes the amount that may be used to advantage per acre is 

 specified. Whenever the product can best be applied by itself, 

 information is furnished as to the best manner of balancing with 

 other ingredients so as to obtain the maximum benefit. 



The second part gives results of experiments to determine the 

 digestibility of cocoanut meal as well as of experiments to deter- 

 mine its food value. It is apparently fully equal in nutritive value 

 to gluten feed, and its use in moderation is favorable to the pro- 

 duction of butter of firm texture. 



Requests for bulletins should be addressed to the 



Agricultural Experiment Station, 



Amherst, Mass.
