20 MAINE AGRICULTURAL EXPERIMENT STATION. 



I916. 



high grade organic nitrogen. The yields are based upon weigh- 

 ings and not upon measure. The potatoes were clean, without 

 adhering soil. 



In potato experiments at Highmoor Farm the Station had 

 found that when there was only a small amount of rainfall 

 following the second application of fertilizer that apparently 

 this added fertilizer was not well utilized. Both seasons, 

 however, at Aroostook Farm there was ample water to dis- 

 solve and render the plant food in all of the fertilizer available. 

 It has been estimated that it takes about 6 inches of water to 

 successfully grow a crop of potatoes. The rainfall each year 

 totaled over 12 inches in May, June, July and August. 



The dates of planting and the yields for both years are given 

 in the tables that follow.
