PURCHASE OF PLANT-FOOD. 



The data contained in the preceding tables afiford a good basis 

 for calHng the attention of farmers to certain facts and for making 

 suggestions connected with the purchase of plant-food. 



(i) Farmers are advised, before purchasing, to obtain for them- 

 selves prices at which they can actually buy plant- food. It should 

 be kept in mind that the prices given as trade-values in Station 

 bulletins are only averages and do not represent accurately all 

 conditions of the market without regard to time or place. Actual 

 trade-values necessarily vary with localities and with different 

 times of the year. The true values to use in making a commer- 

 cial valuation of plant-food are those figures which represent the 

 actual prices at which the farmer can purchase the elements of 

 plant-food at a given time. Quotations should be obtained by 

 making inquiries of several manufacturers, asking at what prices 

 they will furnish the specific forms of plant-food that one wishes 

 to use. The prices thus found enable the farmer to make out his 

 own schedule of valuations and they apply accurately to his 

 special conditions.
