To provide a sufficient amount of food the soil 

 must be heavily treated with barnyard manure. 

 Before planting put a small amount of commer- 

 cial fertilizer in each hill and mix it thoroughly 

 with the soil. 



Potatoes require the greatest amount of pot- 

 ash and the least amount of phosphoric acid. 

 Heavy application of manures produces good 

 results. Thoroughly mix good commercial fer- 

 tilizer in the hill or trench in which the potatoes 

 are to be planted.
