DAIRY AND SEED IMPROVEMENT MEETINGS. 303 



Ques. How much would be lost if the cellar were not 

 cemented as compared with a cemented cellar? 



Ans. The only experiments I have in mind are in feeding 

 steers on cemented and dirt floors, where a loss on ihe dirt 

 floor of 10% nitrogen and 13% of potash was found. 



Ques. Have there been any definite experiments to show 

 the value of the manure applied to the land from a spreader and 

 by hand? 



Ans. As far as the application of manure is concerned, you 

 can get better returns if you spread it over more ground, and 

 you can spread it over more ground with a spreader than you 

 can by hand. I think that to get as much value as possible 

 from a ton of manure a spreader would be advisable. It seems 

 to me that the spreader is an economical proposition with a 

 sufficient number of live stock. 



Ques. Do you recommend housing the manure in barn 

 cellars ? 



Ans. It seems to me that where it is possible you can get 

 better returns by hauling it to the fields, but the barn cellar is 

 a very good way of storing the manure, provided the liquid 

 manure is stored and there is not any loss by decomposition 

 of the cow manure. 



Ques. Isn't the time near by when we are not going to be 

 allowed to use those cellars, when we are producing milk ? 



Ans. I think it is. The use of barn cellars for storing the 

 manure is being prohibited in many states at present. 



Ques. Did I understand you to say that half of the value of 

 the manure is in the liquid form? 



Ans. If we have ten pounds of nitrogen in manure, five 

 pounds is in the liquid form and five pounds in the solid form. 

 About two-thirds of the total potash is in the liquid manure. 

 There is no phosphoric acid, or very little, in the liquid manure. 

 That makes about half the value of the manure in the liquid. 



Ques. Where acid phosphate is used to supplement the 

 manure, what are the results,? 



Ans. Where that has been practiced, very good results have 

 been obtained. This is done in the west, but the conditions 

 there are a little different from what they are here, because in 

 some cases they seem to need only phosphorous fertilizers, 

 while here we need nitrogen and potash in greater quantities.
