expense of manufacture and distribution. Acid i)hosi)hate was used 

 alone in many cases, })articularly on corn. It is doubtless the most 

 economical material to use on these farms as a supplement to so much 

 stable manure and on most crops with tlie possible exception of po- 

 tatoes. 



Lime was used mostly for alfalfa. Plants of medium lime recjuire- 

 ments like red clover will usually respond bountifully on well man- 

 ured soils without liming, but alfalfa is much more exacting. 



The average expenditure for fertilizer amounted to $26 per farm on 

 the whole group of 414 farms. 



FARM MACHINERY 



The average value of all machinery per farm including that part of 

 all automobiles used for farm purposes amounted to $1,064 (Table 28). 

 The manure spreader, milking machine and one or two hay-harvesting 

 machines constitute the most obvious large or expensive pieces of 

 equipment outside of automobiles likely to be found on these farms. 

 Practically every farm has a mowing machine, a hay rake and a hay 

 wagon. The number of milking machines owned and some informa- 

 tion regarding their use are shown in Table 20. Thirty-nine per cent 

 of the farms had milking machines. The numbers of a few other se- 

 lected machines are shown in Table 21.
