266 AGRICULTURE OF MAINE. 



3000 apple trees upon the place which have been set from 15 to 

 25 years. The fields that are not in orchards are well adapted 

 to experiments with corn, potatoes, and similar general farm 

 crops. The house is two story with a large wing, and contains 

 about 15 rooms, well arranged for the Experiment Station offices 

 and for the home of the farm superintendent. The barn is 

 large, afifording storage for hay and grain. The basements of 

 the. building afford a moderate amount of storage for apples, 

 potatoes and roots. 



Although the farm is used as a laboratory by the dififerent 

 departments of the Station and some of the work in progress 

 upon the farm is described in other parts of this report it may 

 be of interest to briefly note the more important investigations 

 that were carried on upon the farm during the growing season 

 for 1912. 



Field Experiments Highmoor Farm. 

 Rotation Experiment. 



The object of this experiment is to ascertain the tlififerences in yields 

 and in the exhaustive effects of corn and potatoes in relation to land 

 treated with chemical fertilizers and with organic manure. The whole 

 field was planted to potatoes on chemical fertilizer in 191 1. It is to be 

 seeded to grass with oats in 1913. 



Plot 5 A. One acre Irish Cobbler potatoes (planted 32 inches deep), 

 with 1700 pounds of 4-8-7 chemical fertilizer. 



Plot 5 B. One acre sweet corn (planted 18 inches in the row), with 

 1700 pounds 4-8-7 chemical fertilizer. 



Plot 5 C. One acre sweet corn (planted 18 inches in the row), with 

 600 pounds 4-8-6 chemical fertilizer plus 8 cords manure. 



Plot 5 D. One acre Irish Cobbler potatoes (planted 3J inches deep), 

 with 600 pounds of 4-8-7 chemical fertilizer plus 8 cords manure. 



Cyanamide Fertilizer Experiment. 



This is in continuation of an experiment started in 191 1 to test the 

 efficiency of a chemically prepared nitrogen supplying fertilizer, known 

 as cyanamide, with the other forms of nitrogen fertilizers now in com- 

 mon use. 



Three plots of one acre each, planted to Irish Cobbler potatoes, ^i 

 inches deep, treated uniformly in respect to phosphoric acid and potash. 

 Nitrogen fertilizers as follows: — 



Plot IS A. 190 pounds nitrate of soda plus 425 pounds dried blood 

 per acre.
